Then you need to contact the Smartfilter support regarding any stability
problems with the modified Squid.

The Squid developers can not support a Squid patched with proprietary
closed-source pathes. The same applies to pretty much any open-source
project, not only Squid.

Again, this you need to discuss with the Smartfilter support. I don't see
why this would be needed, but then I can not look into what Smartfilter
does as I am not a Smartfilter customer.

What I can say is that I can not help with any stability problems with
running a Squid version which includes source modifications not publically
licensed as open-source. Supporting such Squid installations is simply

In additon time does not allow me to investigate stability problems in
older Squid releases. For this reason if you have stability problems the
very first action from your part is to verify that the same stability
problem exists in the current version.

If you have other needs then commercial Squid support agreements are
available from MARA Systems AB <url:>, but the
use of proprietary patches also gives a major problem for any Squid
support agreement as the support agreement can only cover the open-source
components. If there is any doubt on the cause to your problem you will
need to verify that the problem you have exists without the proprietary

For the problems you indicated there is not really any squid.conf changes
which will make a difference from what i can recall but check the list of
known Squid-2.5 bugs just in case. Also check with the Smartfilter
