Re: [squid-users] SOLVED - Squid not caching images/content from certain websites

Dear Squid Users,

I just wanted to let you know I solved this...

In case anyone else using latest stable fedora, gets crazy about this ...

Looks like my version was either buggy or... in any case, the solution
is to upgrade version of Squid.

In latest fedora I did this:

yum install fedora-release-rawhide yum-utils
yum upgrade enablerepo=rawhide squid

Done.

version is now:

Squid Cache: Version 3.4.3

... and Works like a charm and as expected.
