I have a problem with transparent caching.

O/S: Linux Suse 9.0
Platform: Intel X86

Squid Release: 2.5.Stable
Browser: IE6

I have parts transparent caching work just fine with the in the
incoming port of 3128 with my current browser configuration. I have
proxy port set to 3128.

But if I change the configuration on shorewall to redirect all out
going traffic to port 80 traffic from port 3124 is where I have the
experienced this problem.

HTTP and HTTPS works great with the port 3128 from the browser to the
cache server, but when I do a port redirect from port 80 to 3128 the
http works, but the https doesn't with the below shorewall config.

Summary in pictures (ASCII Art)

----------------------------------------------------------------------------
----------------------------------

Browser proxy setting to 3128 ------> firewall ------> 3128 squid

Works great with http and https

----------------------------------------------------------------------------
---------------------------------

Browser proxy setting to 80 ---> firewall --> 80 redirected to 3128

Works great with http, but httpd fails

----------------------------------------------------------------------------
--------------------------------

Here is part of my shorewall config

REDIRECT        net     3128    tcp     http
REDIRECT        net     3128    tcp     https   -       !12.3.34.4
ACCEPT  fw      net     tcp     http
ACCEPT  fw      net     tcp     https

Any ideas? Thanks in advance!!!

Hai,

 If we are configuring T-Proxy then NO need to configure on client browser t
here.  Let us check the problem here.

  http will be using port 80 and https on 443. On using http requests redire
ction, we can only get cached those requests there. Squid supports ftp, goph
er, and https only when clients of each specified protocol are aware of the 
cache. Hence this is not possible when squid is in transparent mode. 

 You can try only with http (80) requests as,

  redirect all 80 requests from any source ---> wall --> 3128 ( squid )

 Refer,
