IMAP Calendar Proxy 1.3

IMAP Calendar Proxy implements an HTTP proxy that converts HTTP PUT requests of vcalendar data to separate messages stored on an IMAP server.

IMAP Calendar Proxy project can be used with Mozilla Sunbird/Calendar to allow storage of a calendar via IMAP.

There are many issues with the program in its current state. Consider it alpha quality, and you may lose calendar data if you use it. Its more of a proof of concept right now. Its rather slow if you have a large calendar.

Ideally IMAP support should be built into Mozilla. This is just a hack. Id like to hear any feedback on how it works. See the TODO file for features Id like to implement.

Sunbird can post calendars to a remote HTTP server via HTTP PUT and to
synchronize via a GET before a PUT. This proxy should run on the same system
you run Sunbird on. It makes a connection to an IMAP server and selects
a specified folder.

It then retrieves all calendar data from that server and caches it it memory. Any changed to the calendar are HTTP PUT to this proxy, and it determines what to do on the IMAP server (delete, change, add). Instead of posting the whole calendar back to the server, it only posts the differences.

If you run the proxy elsewhere on the network, you will not get any bandwidth
savings because the HTTP PUT and GET are still done over the network.
