Hi!
My problem is that the ?AspxAutoDetectCookieSupport=1 on the site pages is the problem for the search robots. They are refused to index the pages with this ?AspxAutoDetectCookieSupport=1. Is there any way to get rid of it?
Please help!

You could change your setting from cookieless="AutoDetect" to cookieless="UseCookies". This will get rid of it, but users without cookies won't be able to pass session objects around. Depending on how you are using sessions, this may or may not matter.

You could also write a routine that sniffs search robots and rewrite the Url, or write .browser files for the search engines you are concerned about.

Thank You for reply on my trouble! I'll try both methods that you have mentioned here!
