Problem in "Content-Type: multipart/form-data;"

Hi Everyone,
I have a site to scrap, when i click a link it sends some post data such as "Content-Type: multipart/form-data; boundary=---------------------------239882929017590
Content-Length: 1345
-----------------------------239882929017590
Content-Disposition: form-data; name="property_types"

MOB
-----------------------------239882929017590
Content-Disposition: form-data; name="country" "

Can anyone say how i have to send the POST data through screen-scraper.

Thanks in advance,
Vivek.
