jQuery AJAX calling ASP.NET WebMethods - Stopped Working

Recently I migrated all code files from ASP.NET Web Application to ASP.NET WebSite (with Framework 4.5.2), because of some requirements we need to move towards website template. At the time I faced this issue, all the ajax calls stopped working. When I placed breakpoint on WebMethod, It was not getting fired.

Here is the WebMethod code:


[WebMethod(EnableSession = true)]
public static string GetPageSummary(string pageid)
{
 string html = "";

 if (!string.IsNullOrEmpty(pageid))
 {
  html = PageHelper.GetPageSummaryHtml(pageid);
 }

 return html;
}

And here is the jquery Ajax call for that method:

$.ajax({

  type: "POST",
  url: "MyPage.aspx/GetPageSummary",
  data: "{ 'pageid':'" + id + "'}",
  contentType: "application/json; charset=utf-8",
  dataType: "json",
  success: function (response) {
   showModelPopupForSummary(response.d)
  },
  error: function (response) {   
   //error-handling code...
  }
 });

It all looks fine and working in previous project, but not with new WebSite project.

After spending way too much time on this, I found out the solution for this.

You have to change enum value for AutoRedirectMode. Go to App_Code/RouteConfig.cs, inside RegisterRoutes() method, you will see this line:

 settings.AutoRedirectMode = RedirectMode.Permanent;

Change the enum value to RedirectMode.Off, final statement would be:

 settings.AutoRedirectMode = RedirectMode.Off;

After changing this all my ajax calls started working successfully.
