Hi,

WebMethod is not calling when I rewrite the urls using HttpModule. Could you please help me. These are my Codes

Client Side

function MyMethod() {
     $.ajax({
         type: 'POST',
         url: 'Test.aspx/TestMethos',
         async: true,
         cache: true,
         dataType: 'json',
         contentType: 'application/json;charset=utf-8',
         data: '{}',
         success: function (data) {
                //MyCode
         },
         error: function (request, status, error) {
             if (request.statusText == 'Unauthorized') {
                 //Logout
             }

}

    });
}

WebMethod

[WebMethod]
public static string TestMethod()
{
    return "Hi Keedam";
}

HttpModule ReWrite C# Code

HttpApplication MyApp = (HttpApplication)sender;
           string MyOldPath = MyApp.Request.Path;
           string OriginalURL = string.Empty;
           switch (MyOldPath.ToLower())
           {
               case "/home":
                   string selectedQueryString = MyApp.Request.QueryString.ToString();
                   OriginalURL = "~/Modules/UserMgmt/Home.aspx";
                   break;
               case "/star performer":
                   OriginalURL = "~/Modules/UserMgmt/BestEmployee.aspx";
                   break;
                case "/test.aspx/testmethod":
                   OriginalURL = "~/Modules/UserMgmt" + MyOldPath;
                   break;

}

if (OriginalURL != string.Empty)
    MyApp.Context.RewritePath(OriginalURL, string.Empty, string.Empty);
