Adding Ajax Detection To HttpRequest

[Daniel Lindsley <polarcowz@…>]

When working in views, I've found it helpful if I can determine if the request was made using Ajax or not, so I can determine what kind of response to send (be it XML, JSON or flat HTML). Most major Javascript libraries/frameworks have standardized on sending the 'X-Requested-With' header with Ajax requests (the list is part of the documentation for the patch). Since this check can occur frequently, I'd like to call a built-in method on HttpRequest. This patch adds that method and some documentation surrounding its use.

I understand that the core team does not wish to align Django with any specific Javascript frameworks/technologies, which this patch does not do. It is agnostic to what you're using, easy for someone who does not use a major library to implement in their Javascript code and is related more toward server-side processing of the request.

Just a tiny bit cleaner than the previous version.

Looks good, I'll test tomorrow @work.

patch works as expected and is documented.

(In [7334]) Fixed #6616 -- Added an is_ajax() method to HttpRequest that uses the de facto
standard header for detecting an XmlHttpRequest call. Thanks, Daniel Lindsley.
