JSON Hijacking and How ASP.NET AJAX 1.0 Avoids these Attacks - ScottGu's Blog
Recently some reports have been issued by security researchers describing ways hackers can use the JSON wire format used by most popular AJAX frameworks to try and exploit cross domain scripts within browsers. Specifically, these attacks use HTTP GET requests invoked via an HTML <script src=""> include element to circumvent the "same origin policy" enforced by browsers (which limits JavaScript objects like XmlHttpRequest to only calling URLs on the same domain that the page was loaded from), and then look for ways to exploit the JSON payload content.

Using jQuery to Consume ASP.NET JSON Web Services | Encosia
In response to many of the articles here, I receive feedback asking how to achieve the same results without using ASP.NET AJAX. As much as I’m a fan of ASP.NET AJAX, I must agree that its JavaScript payload can certainly be a drawback in some situations.
My recent deferred content loading post is an excellent example of that. I was using jQuery for presentational effects, and using a ScriptManager to call a web service. Loading the JavaScript for both frameworks was a bit counterproductive, since the whole point was to improve initial load time.
In this post, I intend to correct that.
First, I’ll cover the two requirements necessary when calling an ASMX web service that’s being JSON serialized by the ASP.NET AJAX extensions. Then, I’ll show you how to do this with jQuery. Finally, I’ll update the deferred content loading example accordingly.
Using jQuery to directly call ASP.NET AJAX page methods | Encosia
When it comes to lightweight client-side communication, I’ve noticed that many of you prefer ASP.NET AJAX’s page methods to full ASMX web services. In fact, page methods came up in the very first comment on my article about using jQuery to consume ASMX web services.
Given their popularity, I’d like to give them their due attention. As a result of Justin’s question in those comments, I discovered that you can call page methods via jQuery. In fact, it turns out that you can even do it without involving the ScriptManager at all.
In this post, I will clarify exactly what is and isn’t necessary in order to use page methods. Then, I’ll show you how to use jQuery to call a page method without using the ScriptManager.
