Asp net validating querystring

04 May

NET proper as the Web Forms View Engine's View Page implementation of Render View() ends up calling Server.

I remember when I first used input validation 7 years ago.

;) If you really know what you're doing and you know WHY you're doing it, you can turn Request Validation off in a number of ways.

Safety mechanisms exist for a reason and if you're going to to use this tip to just "get an app to work" but you're not sure why it's broken and you're just flipping switches to "get'er done" then step backwards out of the minefield and hug your family. Map Path(Virtual Path virtual Path, Virtual Path base Virtual Dir, Boolean allow Cross App Mapping) 639 System.

Don't trust user input and don't let users submit unencoded script or markup.. File IOPermission..ctor(File IOPermission Access access, String path) 92 System.

NET validate request error (‘A potentially dangerous Request.

Form value was detetected…’) which looks like this in ASP.

You’ve just made a relatively simple fix to a solution a nasty morass of hard to discover configuration settings???In this case if I turn it off on my method, it works and I can pass the encoded as directly in the Query String, but STILL not in the Request Path as that's a different path through the server. From Stefan: Note though that the “%” character has special meaning as the beginning of a Url-encoded character sequence. So, with request validation in 2.0 mode and also explicitly turned off on my method: But, remember that a % is a special thing used in URL Encoding (percent encoding) and you can say things that are encoded correctly like ; or things that aren't like %ZZ. You may run into a problem with IIS rejecting the Url depending on what comes after the % sign. The original way this worked was perfectly discoverable via attributes in the page.Now you can set this setting in the page and get completely unexpected behavior and you are required to set what effectively amounts to a backwards compatibility flag in the configuration file.
