c# - AntiForgery cookie in MVC3 -

i wanted implement this solution handle antiforgery in ajax requests. know there other solutions 1 most.

the problem have deal system.web.webpages 1.0 cannot make use of antiforgeryconfig.cookiename in code.

public override void onauthorization(authorizationcontext filtercontext)     {         var request = filtercontext.httpcontext.request;          //  validate posts         if (request.httpmethod == webrequestmethods.http.post)         {             //  ajax posts , normal form posts have treated differently when comes             //  validating antiforgerytoken             if (request.isajaxrequest())             {                 string cookiename = antiforgerydata.getantiforgerytokenname(context.request.applicationpath);                 var antiforgerycookie = request.cookies[antiforgeryconfig.cookiename];                  var cookievalue = antiforgerycookie != null                     ? antiforgerycookie.value                     : null;                  antiforgery.validate(cookievalue, request.headers["__requestverificationtoken"]);             }             else             {                 new validateantiforgerytokenattribute()                     .onauthorization(filtercontext);             }         }     } 

how can retrieve (programmatically) cookie name set antiforgery system in mvc3? suspect antiforgery.validate part problem i'll handle before. thoughts?

the actual cookie name starts "__requestverificationtoken" suffix. can find cookie this:

private static string findcookievaluebyname(httprequestbase request) {     return request.cookies         .cast<string>()         .where(cn => cn.startswith("__requestverificationtoken", stringcomparison.ordinalignorecase))         .select(cn => request.cookies[cn].value)         .firstordefault(); }
