[squid-users] slave proxy problems - squid 2.5

i'm using squid proxy for a long time. no problems until today.

on one machine that's connected with quite slow link to main machine that's
responsible for internet access including WWW caching, i installed slave squid
proxy server with such config

most setting are copied from parent proxy settings that works OK.

this MOSTLY works OK but on many pages that uses some kind of forms (like
search etc.) it waits for a long time and then says "connection timed out".

example:

ERROR
The requested URL could not be retrieved

While trying to retrieve the URL: http://rozklad.pkp.pl/bin/query.exe/pn?

The following error was encountered:

     * Connection Failed

The system returned:

     (60) Connection timed out

The remote host or network may be down. Please try the request again.

Your cache administrator is admin@3miasto.net.

when i temporary switch browser to directly use parent proxy, everything works.

please help!
