Re: [squid-users] Re: Squid not caching. Please help.

Hi, Thanks for your reply.

Here are my comments:

squid.conf was sent earlier before you replied, you can go through and
comment if that looks fine to you or has any issues in it.

Our domain wikid-dev.domain.com points to F5 VIP, which upon receiving
the requests, does two things. 1) http to https redirection if
received in https, 2) SSL Offloading, then forward the requests to
Squid server @ 80. Squid config i had sent earlier which is believed
to be forwarding the requests to two of its cache_peer to its port
443, and cacheing the pages as well. F5 and Squid setup what we have
done is simple and straight forward, we have not done anything
complex. Additionally, F5 uses OneConnect HTTP profile and has
X_Forward enabled and i have kept SourceHash in the cache_peer in
squid.conf to forward the requests to one cache_peer within the same
TCP_connection to avoid any session related problems by blind
round-robin. I will touch on this little later as i would still need
to get my client_ip received from F5, which is not currently
happening. But, right now i am worried about the cacheing that need to
be addressed.

>Why not? 443 and 80 are just ports. Both are just transferring TCP packets. When routing them there is no difference.
Does it make a difference if F5 forward the requests to 443 or 80 to
Squid ? I did that earlier but it never worked but if the cacheing
problem is due to that, i can take your advice on this.
