Bonjour Jeremy,
Here is the answer I got, and I managed to patch squid correctly thanks
to it:

Would you have a corrected patch ?
Because I am applying manually and it is a bit long and not obvious to
not make a mistake.

Hi Christophe,
I think the best is to get the icap branch from cvs:
cvs -d :pserver:[EMAIL PROTECTED]:/cvsroot/squid co
-r icap-2_6 squid
After that run the bootstrap.sh script which included in cvs sources.
Do not try to correct rejected patches. The last merge with main squid26

From your logs what I am seeing is that the

Hello,
Thanks for you support.
I tried the patch from Tsantilas:

Background information:

Hi Beeri,
Maybe you do not need to modify the squid-icap code to support your model.
I think that the correct implementation of your problem using squid-icap
is:
1) An http request come into the squid. Squid sends the reqmod request to
the icap server and server clasifies the request
