great work this library is very of use.
I’m having a problem with ajax query when using the Ajax.ActionLink “XMLHttpRequest”.Equals(request.Headers["X-Requested-With"]
is never true cause i dont have the X-Requested-With passed in the header?

Any idea why ?
Thanks

has an example where he uses custom http response headers which indicate a session timeout. We could make this more generic and call it redirectTo? In the callback you can use getResponseHeader to see if this custom header exists and if it does cause the client to change its location.

Also would this need to use the history plugin to change location?

Obviously this is only required if the request is actually from ajax and if so we could store the redirectTo value in TempData and let the ServiceViewEngine add the custom http response header.

Well thats a quick and nasty way what is everyones thoughts?

I’ve run into a problem when the server needs to perform a response redirect.

http://www.nikhilk.net/Ajax-MVC.aspx (has an explanation of the problem)

The redirect is being handled internally by xmlhttprequest, and the ajax script on the page is getting the content of the redirected to page.

You will need to send back a custom 302 response (i.e, not an actual 302, but a regular 200 response, whose response includes the fact that you need to redirect, and the redirect location).

We need to handle the completed event of the ajax form to see if its this custom response, and instead of letting the update happen, call window.navigate with the new location.

What do you think? Any cool ways to solve this will be much appreciated!
