Log correct file size and MD5SUM.

We try to avoid to reach the max_conn limit.

Content-Type is optional and not well defined, so do not use it.

And remove CGI.pm dependency (because we want nonblocking upload).

and fix a typo

We log to /var/log/pveproxy/access.log. Extra directory is needed because we run

And add init.d script for pveproxy.

bump version to 3.0-6
