[squid-users] Strange problem with squid

Hi List,

i´ve encountered strange problems using squid as proxy together with the
Oracle Application Server, but let me short explain:

The application itself is an ERP-application developed with Oracle Forms
and Runtimes (which ran
originally in client/server-mode). Later on Oracle developed the so
called "Application Server" which
is just an Apache with an JServ-Module for presenting the Forms in the
clients web browser.
On Client-Side runs the Internet Explorer with the so called Oracle
JInitiator (basically an java runtime
environment).

The connection between client and application server uses the http-protocol.

Here we come to my problem:

I´ve tested various combinations for making the application itself
available over my companys
wan-network (basically isdn and vpn-connections) to our customers.
If i am using plain tcp/ip+http i can see with ethereal two tcp
connections to the application server
(good).
But i want to integrante completely into our present infrastructure: All
customers are forced to connect
over an squid 2.5.5-2 proxy for security and access restriction reasons.
So i´ve tested squid as proxy in
this environment.

Firstly i used squid 2.5.4 (from debian testing) which showed > 135 tcp
connections (it seemed keep-alive
is not working properly; i will come to that) and a _extremely_ bad
performance.
After upgrading to squid 2.5.5 the amount of connections doesnt changed
but the performance increased
by factor four (why ??).
If i am using squid 2.4.6 from Debian Stable i have only 2
tcp-connection (like the two i had when using plain
tcp/ip as mentioned befotre).

So i need to know what changed between 2.5.4 and 2.5.5 and what changed
between 2.4.6 and 2.5.5.

Thanks, Ronny.
