Re: Ignore "pragma:no-cache /cache-control:no-cache" header in HTTP request< config help>

[Anonymous cross <anonymouscross@xxxxxxxxx>]

Hi, Amos,

We are using forward tproxy . We used to redirect the packets coming  from client for port 80 to squid proxy server. Squid spoofs the request and establishes a connection with Server transparently. Please find the configuration below

Client --- > Squid proxy server --- > web Server

=====
http_port 3128
http_port 3129 tproxy
http_port 80 accel defaultsite=abcexample.com
refresh_pattern -i abcexample.com/* 600 0% 600 override-expire override-lastmod reload-into-ims ignore-reload
refresh_pattern -i abcexample2.com/* 600 0% 600 override-expire override-lastmod reload-into-ims ignore-reload
=====

Basically we want to increase the page load times by caching the images. Sometimes the specific client is triggering HTTP request with cache-control as no-cache. We want to mandate the packets coming from specific client to be cached in squid to increase the page load times .  In order to avoid serving the stale content we have configured a refresh pattern.

All tht directive controls is what Squid *outputs* to server on its own
upstream requests. It wont help for this question.

Why?

What type of proxy are you running forward/explicit, intercept/tproxy,
or reverse/CDN ?

What does your squid.conf contain?

The client is *demanding* that you dont use stale outdated cache
content. There is usually a good reason for that demand not being a
polite request. So please answer the Qs above.
