squid adding gzip support

Hi,

I am interested in adding support for Content-Encoding: gzip to squid.
I had done some patching, and I managed to get squid compressed
response, but I get corrupted data.
I would like to ask some questions about squid code in order to solve
that problem.
Sample question: size of buffer has to change, since it has compressed
data, but (in client_sice.c: clientSendMoreData())
entry->mem_obj->inmem_hi has the size too. How should I modify this?
May I alter this lvalue directly?
Cheers,
