jQuery.get callback not firing from C# ASP.Net response -

-

I have a Bucommarket, which is clicked on, opens a Div popup on their current page (www .cnn.com). This div has a button, which requests jQuery.get for my application domain when clicking. It's all working fine, but I'm getting an error on the reaction. This is the function that requests 

  function postWishXML () {jQuery ("ServerSponse"). AjaxError (function (event, XMLHttpRequest, ajaxOptions) {// enter here}}; Var Wish = wishObject (); if (will == false) {jQuery ( '. Srhwarrspons'). Html (' Please enter a gift title '); jQuery (' GiftText. ') val (' ').} other {jQuery ('. ServerResponse '). Html (' '); Var WishXML = Create XMLTags (desire); JQuery.get (root +' / app / service / toolbar / Wishlist Popapkshaiks', { 'SAP' cookie, 'desire': WishXML}, Response, 'text');}

}

This is the server code 

  Public Zero Processing Request (HTTP Reference Reference) {if (Se curityContext.IsAuthenticated || SecurityContext.IsSemiAuthenticated) {if (! String.IsNullOrEmpty (context.Request [ "wish"])) {string res = "went the added desire"; Context.Response.ContentType = "text / plain "; context.Response.Write (race); context.Response.End ();   
 Post-text" Aitmprop = "text"> 
 I think you are right It seems that you are killing the cross-site scripting limit. 
 
 Remember, you are putting your javascript code in the code of the targeted website. Therefore, it seems that the code is running from their page. In other words, you are trying to make an AJAX request from within the page (e.g., www.cnn.com) and retrieve data from your site (other domains). 
 
 A solution I found article. This is an abstract: 
 
  function load script (scriptURL) {var scriptElem = document.createElement ('SCRIPT'); ScriptElem.setAttribute ('language', 'javascript'); ScriptElem.setAttribute ('src', scriptURL); Document.body.appendChild (scriptElem); } Load Script (root + '/apps/shop/toolbar/WishlistPopup.ashx');  
 
 Make JavaScript back to your server script that will be eval'ed. 
 
 Use a second, perhaps more preferred option. Basically, your server will respond with JSON data written in a named function. You tell the jQuery.ajax request that you expect a JasonP response and what the name of the returned function will be. It is working very much the above, but wrapped around it with a little more safety and syntax sugar. 
 
 This will be the PHP version, but it should be found throughout the point. Assume that all the data you need is in $ data and keep in mind that you can be able to handle the anonymous work in Jasonson structure successfully. 
 
  $ json = json_encode ($ data); Echo $ _GET ['jsonp_callback'] '('. $ Json. ');';  
 
 Javascript: 
 
  $ Ajax ({dataType: 'jsonp', jsonp: 'jsonp_callback', url: root + '/ apps / shop /toolbar/WishlistPopup.ashx', success: response,});  
 
  To steal the appropriate credit, I stole and modified this JSONP example from the answer of Andrew Moore

c# - How to capture HTTP packet with SharpPcap -

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.

I do not understand why this script does not work. It has something to do within AJAX PostScript / Function. Right now, when I submit my form, it runs php code on the same page. What it should do, send the values ​​of the form for Project_Azax.fp, then there will be a refund of success on the page which is correct or false. $ (document) .ready (function () {$ ('div # didIt'). Hide (); $ ('form [name = adminForm]'). Submit (function () ($ {'.post' ('/ project_ajax.php', {action: $ ('[name = action]') Val (), pId: $ ('[name = pId]'). Val (), name ('[Name = name]'.
