passing information from external asp file and getting it in the portal

Hi,

I think that the answer for my question is simple but I'm not sure how it is done.

I would like to pass information from asp page(microsoft server pages) to the portal and extract the information in the portal

I know how to how to pass the the information as POST or GET method

but how do I extract the infomation within an iView ?

and what is the portal URL I need to call from the asp page ? a page URL or an iView URL ?

Thanks

Y.R
