Remarks

When ASP.NET reads the values in HTTP request collections (such as the Form, QueryString, and Cookies collections), it performs request validation. During request validation, ASP.NET examines the posted values and determines whether they contain markup, script, or reserved characters. By default, if ASP.NET detects any of these types of input, it throws an HttpRequestValidationException exception. This helps prevent malicious script injection attacks on your website.

However, in some cases, you might want to bypass ASP.NET request validation and allow values that contain markup, script, or reserved characters. For example, if your application uses a rich-text editor that enables users to submit HTML markup as formatted content, you can use the members of the UnvalidatedRequestValues class to retrieve the rich-text request values without triggering the default ASP.NET request validation. In your code, you access members of this class by using the Unvalidated property.

Important

If you use this class, you must manually check the data for potential cross-site scripting attacks.
