[squid-users] Squid problems with PHP

Hello.

I have newbie question about squid cache.
I've set up proxy, with attached to this message config, everything runs fine, but when i try to POST something to a large database with interface based on PHP I've got a long timeout ended with message like ERR_ZERO_SIZE_OBJECT. Can this be error in configuration ? or something ?
Problem repeats with:
Proxy: Squid 2.5 and 3.0 devel.
Client: MS IE 5.00 and above
Server: Server: Apache/1.3.27 (Unix) PHP/3.0.18 PHP/4.1.1 mod_ssl/2.8.12 OpenSSL/0.9.6g

Please help :)
