Answer 1

You can use Paypal's Instant Payment Notification (IPN) functionality to process a payment even if the user closes the browser down before they are redirected back to your site.

It's not clear from your question tags if you need a php or an asp.net solution, but the article below provides an excellent breakdown on how to integrate PayPal with a .net web-site -

Answer 2

The solution to that is to use Paypal's IPN (Instant Payment Notification) .

Paypal will post to your IPN script to inform you that a transaction has been affected. This is done server-to-server, so it is more reliable than waiting for the user's browser to return to your site.
