Timeout Error when request a large result query

[arkanimus]

Dear Community,

i'm getting this error and i don't know what to move to extend the timeouts of squid and dansguardian.

Scenario:

We have a web application that runs some heavy querys (reports, procedures, etc) and when someone want to retrieve some info of the DB, the browser show the Empty response error (Error 324(net::ERR_EMPTY_RESPONSE)). if i choose a short interval of days, the report has no problem, but if i choose a long interval of days, when obviously the DB will process more info, i have the error of empty response.

If i disable the proxy, everything goes right, if i enable the proxy, i have the problem.

This are the lines that i add to the squid.conf.mas and dansguardian.conf.mas

Squid.conf.mas

#directivas personalizadas
forward_timeout 4 minutes
connect_timeout 30 minutes
peer_connect_timeout 30 minutes
read_timeout 30 minutes
request_timeout 30 minutes
persistent_request_timeout 30 minutes
pconn_timeout 30 minutes

Dansguardian.conf.mas

contentscannertimeout = 1800 (Default is 60, but i put 1800)

if anyone can help me, i will be very grateful...

Regards

Daniel González.
