Ajax Authentication Response

I have a login form that I am considering if it should be 'ajax'ed or not. The reason I am contemplating this is because if the response of the ajax call is fixed (like 0 for invalid and 1 for valid) I can redirect the ajax request through the javascript console and log into the system maliciously. Is there a way to solve this security i...

What is actually happening to this cancelled HTTP request?

When a user takes a particular action on a page, an Ajax call is made to save their data. Unfortunately, this call is synchronous as they need to wait to see if the data is valid before being allowed to continue. Obviously, this eliminates a lot of the benefit of using Asynchronous JavaScript And XML, but that's a subject for another pos...

Using HTTP status codes to reflect success/failure of Web service request?

I'm implementing a Web service that returns a JSON-encoded payload. If the service call fails -- say, due to invalid parameters -- a JSON-encoded error is returned.

Why are $_POST variables getting escaped in PHP?

When my PHP script receives data from an AJAX POST request, the $_POST variables are escaped. The really strange thing is that this only happens on my production server (running PHP 5.2.12 on Linux) and not on my local server (running PHP 5.3.1 on Windows). Here is the AJAX code: var pageRequest = false; if(window.XMLHttpRequest) p...
