Microsoft has some check the values from the client browser. Because hackers used to post some malicious code which will damage the application.

The posted script is having some text like <

1. In web.config, add the following: this will turn off validate request on all pages

2. In Page markup directive, add the following: this will turn off validate request on specific page

ValidateRequest="false" %>
