Issue with URL length in IIS7 (Windows Server 2008)

Question

Hi, i have an issue with url lengths in iis7. If you go to:

http://demo.kontrolit.com/myaccount/login.htm?ReturnUrl=aa2Fmyaccounta2FdefaultaaspxadnoaauserSuppliedIdentifierahttpa3Aa2Fa2Faaaaaaamaapenidacoma2Fadnoaareturnatoasigahandleaa7B633942228855348748a7Da7BaRINLQa3Da3Da7DadnoaareturnatoasigaxSa2FFPGusD7UvskGqfkJq4QtEYjc4fSVFoa2F3sXNwCBteGOBJ8mipo7yLsuSk2hEgLogbzn6SthYb0wY3pBQM1OQa3Da3Daopenidaassocahandleaa7BHMACaSHA256a7Da7B4b051c2ba7Da7ddufPa2BAa3Da3Da7Daopenidaclaimedaidahttpa3Aa2Fa2Faaaaaaaaaopbnidacoma2Faopenidaidentityahttpa3Aa2Fa2Faaaaaaaabcpenidacoma2Faopenidamodeaidaresaopenidansahttpa3Aa2Fa2Fspec

The page will load fine but if you add one more character to the end it will throw an error. This might seem abit picky to you but it's stopping me from using open id on my login form since it returns a long url. One option i did consider was changing the requestFiltering, therefore in my web.config i have the following:

But this did not resolve the issue. I'd appreciate it if someone could help. Thanks

This is a limitation of Windows and there is currently no workaround
