How to parse an incoming request

I'm trying to figure out how to interpret a request of the standard variety:

I must not know exactly what to look for because I can't find anything in the posts or API. I've used a post/response CGI parse within an action, but this would come in from another site altogether. I need to have this post interpreted and variables assigned from the parameters that it passes. Where should I look for help?

Thank you!


Have you looked at these objects ?

    params     request

-- gw (

Thanks for pointing me in the right direction. I sometimes fail to hit up the "big picture" documentation and just search for specifics. I should be able to get what I'm looking for from the info that you gave.

Thanks again!
