Chapter 9 and 316pages,Request Validation

finkle · July 20th, 2010, 11:36 PM

I setting the ValidateRequest attribute in the @Page directive to False,but it still
throw an exception.
Here is a part of Description:
To allow pages to override application request validation settings,set the requestValidationMode attribute in the httpRuntime configuration section to requestValidationMode="2.0".

Hi there,

As the error message suggests, you need to add <httpRuntime requestValidationMode="2.0" /> to your web.config, like this:

Code:

 
<system.web>
  ...
  <httpRuntime requestValidationMode="2.0" />
  ...
</system.web>

This puts validation in a 2.0 compatible mode, which makes Request Validation work again.

Hope this helps,

Imar

maybe author forgot to write <httpRuntime requestValidationMode="2.0" />
settings in the book or this settings is default in asp.net 4 for security.

The need to add the attribute was added to .NET after I sent in my chapter to Wrox, so I wasn't aware of the problem until after the book was released.

And no, it's not a bug in .NET; it's a feature: http://www.asp.net/learn/whitepapers...__Toc256770147
