jQuery Ajax Request Gets no Reponse on IIS 7.5

Sending jquery ajax request to ASP.NET 4.5.1 web:

var request = $.ajax({
        url: 'ajax.ashx?' + ajaxMethod,
        dataType: 'json',
        responseType: "json",
        contentType: 'application/x-www-form-urlencoded; charset=UTF-8',
        type: "POST",
        data: data
    });

When using IIS Express the server receives the ajax request.
When using IIS 7.5 the server does not receives the ajax request.
Notes:
There was no problem on my old PC with this web site. The problem started on a new PC.
No problem with .aspx pages.

Solution

  • Solved.
    The problem was permission to access SQL Server using trusted connection.
    After changing the connection string to use User/Password connection it works.
