datagrid is picking up data from REQUEST it should not

[GoogleCodeExporter]

What steps will reproduce the problem?
1. my datagrid is in a page that is called in an iframe with a post request
2. so the urls generated in the datagrid for navigation and sort have the added 
parameters from the iframe post which makes the links fail
3. so the sort url from the datagrid looks like that:
/index/index/mid/1/lang/en/country/US/view/canvas/parent/http%3A%2F%2Fcgi6.ebay.
com%2Fws%2F/rpctoken/634622016/env/production/globalid/EBAY-US/sp/mid%2Clang%

mid/1
lang/en, .... are from the iframe post.
I tried to clear $_REQUEST=NULL; to no avail
I tried $_SERVER['QUERY_STRING']; same thing so I am unsure how to clkear the 
REQUEST before calling the grid ?!?!?

Thanks

                unset($_POST);
                unset($_GET);
before loading the datagrid solved my problem
