Note that node.js v0.6.2+ bundles punycode by default.\n\nWhy the name?  NPM modules `cookie`, `cookies` and `cookiejar` were already taken.\n\n# API\n\ntough\n=====\n\nFunctions on the module you get from `require('tough-cookie')`.  All can be used as pure functions and don't need to be \"bound\".\n\nparseDate(string[,strict])\n-----------------\n\nParse a cookie date string into a `Date`.  Parses according to RFC6265 Section 5.1.1, not `Date.parse()`.  If strict is set to true then leading/trailing non-seperator characters around the time part will cause the parsing to fail (e.g. \"Thu, 01 Jan 1970 00:00:010 GMT\" has an extra trailing zero but Chrome, an assumedly RFC-compliant browser, treats this as valid).\n\nformatDate(date)\n----------------\n\nFormat a Date into a RFC1123 string (the RFC6265-recommended format).\n\ncanonicalDomain(str)\n--------------------\n\nTransforms a domain-name into a canonical domain-name.  The canonical domain-name is a trimmed, lowercased, stripped-of-leading-dot and optionally punycode-encoded domain-name (Section 5.1.2 of RFC6265).  For the most part, this function is idempotent (can be run again on its output without ill effects).\n\ndomainMatch(str,domStr[,canonicalize=true])\n-------------------------------------------\n\nAnswers \"does this real domain match the domain in a cookie?\".  The `str` is the \"current\" domain-name and the `domStr` is the \"cookie\" domain-name.  Matches according to RFC6265 Section 5.1.3, but it helps to think of it as a \"suffix match\".\n\nThe `canonicalize` parameter will run the other two paramters through `canonicalDomain` or not.\n\ndefaultPath(path)\n-----------------\n\nGiven a current request/response path, gives the Path apropriate for storing in a cookie.  This is basically the \"directory\" of a \"file\" in the path, but is specified by Section 5.1.4 of the RFC.\n\nThe `path` parameter MUST be _only_ the pathname part of a URI (i.e. excludes the hostname, query, fragment, etc.).  This is the `.pathname` property of node's `uri.parse()` output.\n\npathMatch(reqPath,cookiePath)\n-----------------------------\n\nAnswers \"does the request-path path-match a given cookie-path?\" as per RFC6265 Section 5.1.4.  Returns a boolean.\n\nThis is essentially a prefix-match where `cookiePath` is a prefix of `reqPath`.\n\nparse(header[,strict=false])\n----------------------------\n\nalias for `Cookie.parse(header[,strict])`\n\nfromJSON(string)\n----------------\n\nalias for `Cookie.fromJSON(string)`\n\ngetPublicSuffix(hostname)\n-------------------------\n\nReturns the public suffix of this hostname.  The public suffix is the shortest domain-name upon which a cookie can be set.  Returns `null` if the hostname cannot have cookies set for it.\n\nFor example: `www.example.com` and `www.subdomain.example.com` both have public suffix `example.com`.\n\nFor further information, see http://publicsuffix.org/.  This module derives its list from that site.\n\ncookieCompare(a,b)\n------------------\n\nFor use with `.sort()`, sorts a list of cookies into the recommended order given in the RFC (Section 5.4 step 2).  Longest `.path`s go first, then sorted oldest to youngest.\n\n``` javascript\nvar cookies = [ /* unsorted array of Cookie objects */ ];\ncookies = cookies.sort(cookieCompare);\n```\n\npermuteDomain(domain)\n---------------------\n\nGenerates a list of all possible domains that `domainMatch()` the parameter.  May be handy for implementing cookie stores.\n\n\npermutePath(path)\n-----------------\n\nGenerates a list of all possible paths that `pathMatch()` the parameter.  May be handy for implementing cookie stores.\n\nCookie\n======\n\nCookie.parse(header[,strict=false])\n-----------------------------------\n\nParses a single Cookie or Set-Cookie HTTP header into a `Cookie` object.  Returns `undefined` if the string can't be parsed.  If in strict mode, returns `undefined` if the cookie doesn't follow the guidelines in section 4 of RFC6265.  Generally speaking, strict mode can be used to validate your own generated Set-Cookie headers, but acting as a client you want to be lenient and leave strict mode off.\n\nHere's how to process the Set-Cookie header(s) on a node HTTP/HTTPS response:\n\n``` javascript\nif (res.headers['set-cookie'] instanceof Array)\n  cookies = res.headers['set-cookie'].map(function (c) { return (Cookie.parse(c)); });\nelse\n  cookies = [Cookie.parse(res.headers['set-cookie'])];\n```\n\nCookie.fromJSON(string)\n-----------------------\n\nConvert a JSON string to a `Cookie` object.  Does a `JSON.parse()` and converts the `.created`, `.lastAccessed` and `.expires` properties into `Date` objects.\n\nProperties\n==========\n\n  * _key_ - string - the name or key of the cookie (default \"\")\n  * _value_ - string - the value of the cookie (default \"\")\n  * _expires_ - `Date` - if set, the `Expires=` attribute of the cookie (defaults to the string `\"Infinity\"`). See `setExpires()`\n  * _maxAge_ - seconds - if set, the `Max-Age=` attribute _in seconds_ of the cookie.  May also be set to strings `\"Infinity\"` and `\"-Infinity\"` for non-expiry and immediate-expiry, respectively.  See `setMaxAge()`\n  * _domain_ - string - the `Domain=` attribute of the cookie\n  * _path_ - string - the `Path=` of the cookie\n  * _secure_ - boolean - the `Secure` cookie flag\n  * _httpOnly_ - boolean - the `HttpOnly` cookie flag\n  * _extensions_ - `Array` - any unrecognized cookie attributes as strings (even if equal-signs inside)\n\nAfter a cookie has been passed through `CookieJar.setCookie()` it will have the following additional attributes:\n\n  * _hostOnly_ - boolean - is this a host-only cookie (i.e. no Domain field was set, but was instead implied)\n  * _pathIsDefault_ - boolean - if true, there was no Path field on the cookie and `defaultPath()` was used to derive one.\n  * _created_ - `Date` - when this cookie was added to the jar\n  * _lastAccessed_ - `Date` - last time the cookie got accessed. Will affect cookie cleaning once implemented.  Using `cookiejar.getCookies(...)` will update this attribute.\n\nConstruction([{options}])\n------------\n\nReceives an options object that can contain any Cookie properties, uses the default for unspecified properties.\n\n.toString()\n-----------\n\nencode to a Set-Cookie header value.  The Expires cookie field is set using `formatDate()`, but is omitted entirely if `.expires` is `Infinity`.\n\n.cookieString()\n---------------\n\nencode to a Cookie header value (i.e. the `.key` and `.value` properties joined with '=').\n\n.setExpires(String)\n-------------------\n\nsets the expiry based on a date-string passed through `parseDate()`.  If parseDate returns `null` (i.e. can't parse this date string), `.expires` is set to `\"Infinity\"` (a string) is set.\n\n.setMaxAge(number)\n-------------------\n\nsets the maxAge in seconds.  Coerces `-Infinity` to `\"-Infinity\"` and `Infinity` to `\"Infinity\"` so it JSON serializes correctly.\n\n.expiryTime([now=Date.now()])\n-----------------------------\n\n.expiryDate([now=Date.now()])\n-----------------------------\n\nexpiryTime() Computes the absolute unix-epoch milliseconds that this cookie expires. expiryDate() works similarly, except it returns a `Date` object.  Note that in both cases the `now` parameter should be milliseconds.\n\nMax-Age takes precedence over Expires (as per the RFC). The `.created` attribute -- or, by default, the `now` paramter -- is used to offset the `.maxAge` attribute.\n\nIf Expires (`.expires`) is set, that's returned.\n\nOtherwise, `expiryTime()` returns `Infinity` and `expiryDate()` returns a `Date` object for \"Tue, 19 Jan 2038 03:14:07 GMT\" (latest date that can be expressed by a 32-bit `time_t`; the common limit for most user-agents).\n\n.TTL([now=Date.now()])\n---------\n\ncompute the TTL relative to `now` (milliseconds).  The same precedence rules as for `expiryTime`/`expiryDate` apply.\n\nThe \"number\" `Infinity` is returned for cookies without an explicit expiry and `0` is returned if the cookie is expired.  Otherwise a time-to-live in milliseconds is returned.\n\n.canonicalizedDoman()\n---------------------\n\n.cdomain()\n----------\n\nreturn the canonicalized `.domain` field.  This is lower-cased and punycode (RFC3490) encoded if the domain has any non-ASCII characters.\n\n.validate()\n-----------\n\nStatus: *IN PROGRESS*. Works for a few things, but is by no means comprehensive.\n\nvalidates cookie attributes for semantic correctness.  Useful for \"lint\" checking any Set-Cookie headers you generate.  For now, it returns a boolean, but eventually could return a reason string -- you can future-proof with this construct:\n\n``` javascript\nif (cookie.validate() === true) {\n  // it's tasty\n} else {\n  // yuck!\n}\n```\n\nCookieJar\n=========\n\nConstruction([store = new MemoryCookieStore()][, rejectPublicSuffixes])\n------------\n\nSimply use `new CookieJar()`.  If you'd like to use a custom store, pass that to the constructor otherwise a `MemoryCookieStore` will be created and used.\n\n\nAttributes\n----------\n\n  * _rejectPublicSuffixes_ - boolean - reject cookies with domains like \"com\" and \"co.uk\" (default: `true`)\n\nSince eventually this module would like to support database/remote/etc. CookieJars, continuation passing style is used for CookieJar methods.\n\n.setCookie(cookieOrString, currentUrl, [{options},] cb(err,cookie))\n-------------------------------------------------------------------\n\nAttempt to set the cookie in the cookie jar.  If the operation fails, an error will be given to the callback `cb`, otherwise the cookie is passed through.  The cookie will have updated `.created`, `.lastAccessed` and `.hostOnly` properties.\n\nThe `options` object can be omitted and can have the following properties:\n\n  * _http_ - boolean - default `true` - indicates if this is an HTTP or non-HTTP API.  Affects HttpOnly cookies.\n  * _secure_ - boolean - autodetect from url - indicates if this is a \"Secure\" API.  If the currentUrl starts with `https:` or `wss:` then this is defaulted to `true`, otherwise `false`.\n  * _now_ - Date - default `new Date()` - what to use for the creation/access time of cookies\n  * _strict_ - boolean - default `false` - perform extra checks\n  * _ignoreError_ - boolean - default `false` - silently ignore things like parse errors and invalid domains.  CookieStore errors aren't ignored by this option.\n\nAs per the RFC, the `.hostOnly` property is set if there was no \"Domain=\" parameter in the cookie string (or `.domain` was null on the Cookie object).  The `.domain` property is set to the fully-qualified hostname of `currentUrl` in this case.  Matching this cookie requires an exact hostname match (not a `domainMatch` as per usual).\n\n.setCookieSync(cookieOrString, currentUrl, [{options}])\n-------------------------------------------------------\n\nSynchronous version of `setCookie`; only works with synchronous stores (e.g. the default `MemoryCookieStore`).\n\n.storeCookie(cookie, [{options},] cb(err,cookie))\n-------------------------------------------------\n\n__REMOVED__ removed in lieu of the CookieStore API below\n\n.getCookies(currentUrl, [{options},] cb(err,cookies))\n-----------------------------------------------------\n\nRetrieve the list of cookies that can be sent in a Cookie header for the current url.\n\nIf an error is encountered, that's passed as `err` to the callback, otherwise an `Array` of `Cookie` objects is passed.  The array is sorted with `cookieCompare()` unless the `{sort:false}` option is given.\n\nThe `options` object can be omitted and can have the following properties:\n\n  * _http_ - boolean - default `true` - indicates if this is an HTTP or non-HTTP API.  Affects HttpOnly cookies.\n  * _secure_ - boolean - autodetect from url - indicates if this is a \"Secure\" API.  If the currentUrl starts with `https:` or `wss:` then this is defaulted to `true`, otherwise `false`.\n  * _now_ - Date - default `new Date()` - what to use for the creation/access time of cookies\n  * _expire_ - boolean - default `true` - perform expiry-time checking of cookies and asynchronously remove expired cookies from the store.  Using `false` will return expired cookies and **not** remove them from the store (which is useful for replaying Set-Cookie headers, potentially).\n  * _allPaths_ - boolean - default `false` - if `true`, do not scope cookies by path. The default uses RFC-compliant path scoping. **Note**: may not be supported by the CookieStore `fetchCookies` function (the default MemoryCookieStore supports it).\n\nThe `.lastAccessed` property of the returned cookies will have been updated.\n\n.getCookiesSync(currentUrl, [{options}])\n----------------------------------------\n\nSynchronous version of `getCookies`; only works with synchronous stores (e.g. the default `MemoryCookieStore`).\n\n.getCookieString(...)\n---------------------\n\nAccepts the same options as `.getCookies()` but passes a string suitable for a Cookie header rather than an array to the callback.  Simply maps the `Cookie` array via `.cookieString()`.\n\n.getCookieStringSync(...)\n-------------------------\n\nSynchronous version of `getCookieString`; only works with synchronous stores (e.g. the default `MemoryCookieStore`).\n\n.getSetCookieStrings(...)\n-------------------------\n\nReturns an array of strings suitable for **Set-Cookie** headers. Accepts the same options as `.getCookies()`.  Simply maps the cookie array via `.toString()`.\n\n.getSetCookieStringsSync(...)\n-----------------------------\n\nSynchronous version of `getSetCookieStrings`; only works with synchronous stores (e.g. the default `MemoryCookieStore`).\n\nStore\n=====\n\nBase class for CookieJar stores.\n\n# CookieStore API\n\nThe storage model for each `CookieJar` instance can be replaced with a custom implementation.  The default is `MemoryCookieStore` which can be found in the `lib/memstore.js` file.  The API uses continuation-passing-style to allow for asynchronous stores.\n\nStores should inherit from the base `Store` class, which is available as `require('tough-cookie').Store`.  Stores are asynchronous by default, but if `store.synchronous` is set, then the `*Sync` methods on the CookieJar can be used.\n\nAll `domain` parameters will have been normalized before calling.\n\nThe Cookie store must have all of the following methods.\n\nstore.findCookie(domain, path, key, cb(err,cookie))\n---------------------------------------------------\n\nRetrieve a cookie with the given domain, path and key (a.k.a. name).  The RFC maintains that exactly one of these cookies should exist in a store.  If the store is using versioning, this means that the latest/newest such cookie should be returned.\n\nCallback takes an error and the resulting `Cookie` object.  If no cookie is found then `null` MUST be passed instead (i.e. not an error).\n\nstore.findCookies(domain, path, cb(err,cookies))\n------------------------------------------------\n\nLocates cookies matching the given domain and path.  This is most often called in the context of `cookiejar.getCookies()` above.\n\nIf no cookies are found, the callback MUST be passed an empty array.\n\nThe resulting list will be checked for applicability to the current request according to the RFC (domain-match, path-match, http-only-flag, secure-flag, expiry, etc.), so it's OK to use an optimistic search algorithm when implementing this method.  However, the search algorithm used SHOULD try to find cookies that `domainMatch()` the domain and `pathMatch()` the path in order to limit the amount of checking that needs to be done.\n\nAs of version 0.9.12, the `allPaths` option to `cookiejar.getCookies()` above will cause the path here to be `null`.  If the path is `null`, path-matching MUST NOT be performed (i.e. domain-matching only).\n\nstore.putCookie(cookie, cb(err))\n--------------------------------\n\nAdds a new cookie to the store.  The implementation SHOULD replace any existing cookie with the same `.domain`, `.path`, and `.key` properties -- depending on the nature of the implementation, it's possible that between the call to `fetchCookie` and `putCookie` that a duplicate `putCookie` can occur.\n\nThe `cookie` object MUST NOT be modified; the caller will have already updated the `.creation` and `.lastAccessed` properties.\n\nPass an error if the cookie cannot be stored.\n\nstore.updateCookie(oldCookie, newCookie, cb(err))\n-------------------------------------------------\n\nUpdate an existing cookie.  The implementation MUST update the `.value` for a cookie with the same `domain`, `.path` and `.key`.  The implementation SHOULD check that the old value in the store is equivalent to `oldCookie` - how the conflict is resolved is up to the store.\n\nThe `.lastAccessed` property will always be different between the two objects and `.created` will always be the same.  Stores MAY ignore or defer the `.lastAccessed` change at the cost of affecting how cookies are sorted (or selected for deletion).\n\nStores may wish to optimize changing the `.value` of the cookie in the store versus storing a new cookie.  If the implementation doesn't define this method a stub that calls `putCookie(newCookie,cb)` will be added to the store object.\n\nThe `newCookie` and `oldCookie` objects MUST NOT be modified.\n\nPass an error if the newCookie cannot be stored.\n\nstore.removeCookie(domain, path, key, cb(err))\n----------------------------------------------\n\nRemove a cookie from the store (see notes on `findCookie` about the uniqueness constraint).\n\nThe implementation MUST NOT pass an error if the cookie doesn't exist; only pass an error due to the failure to remove an existing cookie.\n\nstore.removeCookies(domain, path, cb(err))\n------------------------------------------\n\nRemoves matching cookies from the store.  The `path` paramter is optional, and if missing means all paths in a domain should be removed.\n\nPass an error ONLY if removing any existing cookies failed.\n\n# TODO\n\n  * _full_ RFC5890/RFC5891 canonicalization for domains in `cdomain()`\n    * the optional `punycode` requirement implements RFC3492, but RFC6265 requires RFC5891\n  * better tests for `validate()`?\n\n# Copyright and License\n\n(tl;dr: MIT with some MPL/1.1)\n\nCopyright 2012- GoInstant, Inc. and other contributors.
