Asp net validating querystring carbon dating formula explained
It's nice to be protected, but sometimes you want to accept potentially dangerous input, or maybe you just don't want to have that error splashed across the screen. For both web forms and MVC, you add this to attribute to the appropriate controller or action.
The latter was the case for me recently, but I wasn't completely happy with the standard solution. Being a fan of prevention rather than cure, and liking aspect-oriented solutions to problems, I figured it'd be nicer to screen input before it gets to my MVC application than stick attributes all over the place.
For example, imagine that you had a website with a page where a user could modify their account.As we'll see, only a few short lines of code are needed to both generate the signature on the page generating the hyperlink and validating the signature on the "receiving" page. When creating web pages that accept user-defined inputs, be it through the querystring or a form, you should always do validation on the provided values.For example, if you have a site that has a page called , and only certain users can see certain products, it's imperative that in the web page's source code you always verify that the current user has permission to view the requested product.If someone injects another value at last for the same text box in the posted request, the value would come like 'Test, Mallicous Value'. In short, want to get rid of HTTP Parameter Pollution. Hi, Glad you've found it useful :) If someone decides to post junk to your site, there's not really anything you can do to identify which bits they've sent are junk, and which bits aren't. Normally it works fine for me but it don't work as expected when Ajax calls come into the picture.You could adapt the above Http Module to add a parameter to requests where HTML tags have been removed or where there are multiple values for the same form key, but you'd have to review flagged requests manually to see if you thought they really were junk. I can read the querystring colletion of ajax request but some how its not upating the collection value.
