cleansing query string after third party redirect to my site

[eluser]cwpollock[/eluser]
I am trying to get paypal to return a customer to a site.. when it returns it sticks a bunch of query string information on the end:

http://mywebsite.com/paypal/success/?mer...rset=UTF-8

This breaks my app. Any thoughts on how to handle this?

Are you using IPN?

In your form you send to paypal, you should have a extra hidden form field with with the name "rm"and the value of "2" which means that the return should be post data.

I hope that helps!
