If the client connects to the internet via a proxy server, the communication with the comet server fails:

====
ERROR
The requested URL could not be retrieved

While trying to retrieve the URL: http://www.myapp.de:443/

The following error was encountered:

    * Zero Sized Reply 

Squid did not receive any data for this request.
====

This error disables the flash communication. The client falls back to xhr, which does not work at least with mozilla,
because the javascript sent by the comet server does not have the same origin as the displayed page. There is already
a bug filed related to this problem.

When the client connects to the internet without a proxy everything works fine.


I tried to workarund this by using the apache mod_proxy. So every request to myapp.de/comet should be proxied to
127.0.0.1:443 (CometPort). But this proxying also fails:
Error Reason: Error reading from remote server

I assume the reason is again the zero sized reply.
