Doubt with SQUID Cache

Hi.

I am newbie with Squid, I have already installed and running in my Server but I want to reconfigure it to do this:

When my server receive this request: xxx.com/req?x=50&y=100
it creates a serialized object and return it via browser

I want to squid catch this serialized object and store it so when another person request the same direction, instead of creating again the object, the cache object will be returned.

Can this be done? and how?

I know that for rule all dynamic content is not meant to be cached but my requirements ask me to.

Thanks.

I am looking to do the same thing, what version are you using?
