X-Requested-With header not set in jquery ajaxForm plugin

Question

I\'m using the jQuery ajaxForms plugin to make an ajax submit to my CakePHP app.

Cake\'s RequestHandler detects ajax requests by looking at the \"X-Requested-With\

Answer 1

I found the problem to be lack of support for file uploads in older versions of the plugin. When I removed the file inputs, the problem went away.
