Changing Post requests on the fly?

This is along the same lines as using proxy...

I am working on scraping a site that uses POST for parameters other than login, but for submitting info rather.

I want to submit an array of information.

Is there a way to change the value of the POSTed parameters on the fly (I.E. set it to some kind of variable and control the variable before the POST occurs?)

I'll post again if I need more help

What I want to do seems to be related to this forum post

"Repeat scrape with different date in post parameter" at http://www.screen-scraper.com/forum/phpBB2/viewtopic.php?t=183

But I couldn't follow it the whole way. I could follow how you were changing the "date" variable in the script, and then running the scrape. But I could not tell how you were associating the "Date" variable in the script with the POST parameter in the scrape. All i know how to do is fixed values for POST data.
