How to parse an incoming request

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

http://www.domain.com/controller/action?VAR1=val1&VAR2=val2

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

http://api.rubyonrails.org/classes/ActionController/Base.html

-- gw (www.railsdev.ws)

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!
