I think this is a nice and smart way. It works if on the single page:1) all data (which is going to be POSTed) are persisted in the;2) the token is also inside that.The above $.postAntiForgery and $.ajaxAntiForgery can work for general scenarios. In many pages, not all data for POST are persisted with one element. And the token would not be always inside one form element. There are many ajax pages with no elements at all. And the data might be represented in many ways (like an ). Sometimes token could be even in another window (consider the iframe and dialog scenarios).And in most cases, all that need to do is replacing $.post invocation with $.postAntiForgery.

I hope this could be as simple as your solution:)-. ASP.NET MVC’s anti-CSRF helpers work very nicely, but you should be aware of a few limitations:All legitimate visitors must accept cookies (otherwise, ValidateAntiForgeryToken will deny their form posts).

Arguably this isn’t a limitation, because unless visitors allow cookies, you probably don’t have anything to protect anyway.It only works with POST requests, not GET requests. Arguably this isn’t a limitation, because under the normal HTTP conventions, you shouldn’t be using GET requests for anything other than read-only operations.It’s easily bypassed if you have any XSS holes on your domain. An XSS hole would allow an attacker to read a victim’s anti-forgery token value, then use it to forge valid posts. So, don’t have XSS holes!It relies on the potential victim’s browser implementing cross-domain boundaries solidly. Browsers are supposed to stop foreign domains from reading your app’s response text and cookies, and are supposed to stop foreign domains from writing cookies to your domain. If an attacker manages to find a way around this, they can bypass ValidateAntiForgeryToken. Of course that’s not supposed to be possible.

For the most part, modern browsers block this line of attack.-. Yes it works.I'm just wondering about the case of a ajax request without a form- Actually this is quite usual. Many user interactions are implemented without a element.it will fail anyway because the validation on the server needs the token to the included on the collection Request.Form and then compare with the cookie.- As long as browser sends data with 'POST' http request, server gets the data in Request.Form. Submitting a will send a 'POST' reques. And an ajax 'POST' request does the same thing. You can use the tool 'fiddler' to check the detail of either http request (form / ajax). You will see they are the same thing.-.

@Cristiano DiasI am not sure what happened in your website because I cannot see your project. Please make sure you have this in your HTML:and you have this in your cookie (in your ajax POST request's header):RequestVerificationTokenLw=J56khgCvbE3bVcsCSZkNVuH9Cclm9SSIT/ywruFsXEgmV8CL2eW5C/gGsQUf/YuPand you have this in your ajax POST request's body.&RequestVerificationToken=J56khgCvbE3bVcsCSZkNVuH9Cclm9SSIT/ywruFsXEgmV8CL2eW5C/gGsQUf/YuPYou can use fiddler to observe your ajax requests: http://www.fiddler2.com/fiddler2/-.

500 – The required anti-forgery form field “RequestVerificationToken” is not present. Mean that the token were unable to post back to controller to be verify. The token was missing.

I seldom leave comments, however i did a few searching and woundup here Anti-Forgery Request Recipes For ASP.NET MVC And AJAX - Dixin's Blog.And I do have 2 questions for you if it's allright.Is it only me or does it look like some of the remarks appear as ifthey are coming from brain dead people?:-P And, if youare posting at other social sites, I'd like to follow everything new you have to post.Could you make a list of every one of allyour shared pages like your Facebook page, twitter feed, or linkedin profile?-.
