How to create a post form, without using a form.(PERL)

Here's where I'm at:

I have all the information a user wants submitted to a form, and now, using PERL, I need to create the correct headers and send them to an outside site.

For example:  I know the user wants to know the weather in Detroit, I want to pass information to the Weather Channel just as if it had come from the www.weather.com POST form in the first place.  

I have this working for GET forms, I just call the form-submit URL and ?append the variables.  I want to know how to do this for POST forms.

Can anyone please walk or pseudocode (Heck, or even show code!) me through this?

It looks like their POST form just directs you to another url, e.g.
http://www.weather.com/weather/us/cities/MI_Detroit.html
So couldn't you just send your user to that same url?

You need two header fields:

Content_type: application/x-www-form-urlencoded\r\n
Content_length: XXX\r\n
\r\n
name1=val1&name2=val2

The entity body is something like the query string.  XXX is the size of the body, remember that you need an empty line before the body.
