Hi all,

Recently I had to set-up our external http proxy (apache 1.3.x) in such a way that it accepts rsync traffic coming from our
lan.

So I decided to add a 'CONNECT' in my httpd.conf. This is all working now but not so fine as I could expect it. Sometimes
the communication is broken and I get this error message coming from rsync :

 ...
 rsync: connection unexpectedly closed ... [receiver]
 rsync error: error in rsync protocol data stream (code 12) at io.c(443) rsync: connection unexpectedly closed ... 
[generator]
 rsync error: error in rsync protocol data stream (code 12) at io.c(443) ...

I give you below my current config.
