Is it possible to use Response.Redirect to send a user to Paypal to make a payment?

Does anyone have experience with something like this?  I am new, so please include as much detail as possible.

I was planning to try the following code:

Response.Redirect(http://www.paypal.com/cgi-bin/webscr?business=mybusiness&item_name=membership&amount_1=20.00)

This doesn't work though.
