Solution 1

Any request which includes "<" and ">" characters is "potentially dangerous" as it could involve HTML Injection and / or cross site scripting attacks.

Check your requests, and if you have such characters legitimately in them, consider changing them to underscores to avoid the message. If you don't, then you need to look at what is going on in a lot more detail!

Thanks for your suggestion buddy. here mostly my url with out special character. But testing team manually check url with special character. I wants to redirect my site to error.aspx page if url contain such characters. Is there any possibilities please let me know.

Are you catching custom errors and redirecting them all to an error page?
If you are and it isn't working, you need to look at either using a try...catch in your C# / VB code round the request, or using HTML encode to convert them to "normal" data.
