I have used the httprequest to get some parameter from the url, so that the page url is http://xxx.com/test.aspx?operation=1&......
But the error message told that the URL encode is not valid.
What is the cause of the error and how to solve it? Thank you.

Regards,
Kev

Kev:

I'm not sure if this is applicable to your situation, since I'm not privy to the details of your database update, but this recent post (1/18/2012) is worth reviewing, if you've not yet done so:

MS Update MS11-100 breaks sites with more than 1000 parameters at http://world.episerver.com/Blogs/Per-Nilsson/Dates/2012/1/MS-Update-MS11-100-breaks-sites-with-more-than-1000-parameters/

Hope this helps!

Typical MS answer to a problem: rather than fix the underlying implementation by backing the Request collection with a data structure not vulnerable to malicious O(N) search complexity (like, oh, maybe a binary tree?), they throw a magic number at it and hope it goes away.

Well put, Keith. I agree wholeheartedly.

Cheers!
