We have proxy implemented in our office, I need to make webservice call using jQuery AJAX.

If we skip proxy, the web method gets called without any errors.
But the moment we enable proxy, we get "NetworkError" no more details available regarding this error.

We cannot disable proxy forever, now we want to call this webservice using jQuery AJAX.
Please help me resolve the issue.

var surl = "";
    type: 'GET',
    url: surl,
    crossDomain: true,
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    xhrFields: {
         withCredentials: true
    success: function(data, statusCode, xhr) {
    error: function(xhr, status, error) { 
        alert('Error !!'); 
    async: false,
    cache: false

When proxy is on, can you browse your site?
did you heard about jQuery.ajaxPrefilter()?

Yes when proxy is on I can browse the site.<br>
I have set jQuery.ajaxPrefilter(), and set async to true.<br>
Now I get a new error called "error" with status code "0" and status text "error"

Please try is as below.

Note: This is just a sample.Adjust it according to your app.

$.ajaxPrefilter( function( options ) {
  if ( options.crossDomain ) {
    var newData = {};
    // Copy the object to the property.
    // We need to do this because javascript doesn't deep-copy variables by default. = $.extend({},;
    newData.url = options.url;

    // Reset the options object - we'll re-populate in the following lines.
    options = {};

    // Set the proxy URL
    options.url = ""; = $.param(newData);
    options.crossDomain = false;
