Question

As in title, i have an asp.net 4.0 web forms project working fine.
As i try to move jquery from 1.7.2 to 1.9.0 i get

HTTP 405.0 – Method Not Allowed

As i try to load htm files through ajax.
Sample code causing error

$("#samplediv").load("/htmlParts/ComunicazioniAlerts.htm?p=" + now(), function () {
    alert('loaded');
}); 

Code that works perfectly with older jquery version.

I’m putting the upgrade to stand-by, seems a method/verb problem but shows only when updgrading jquery, as if they changed the way they require pages.

Answer 1

Found.
I use many ajax calls in my app and to avoid repeating i put on top of my app this

$.ajaxSetup({
    type: "POST",
    contentType: "application/json; charset=utf-8",
    data: "{}",
    dataType: "json"
});

In 1.7.2 this wasn’t applying to $.load() that kept using GET method.
Now in 1.9.0 also $.load considers the $.ajaxsetup, sends requests with POST method for htm files and IIS refuses the request.

Possible workaround:
– on IIS enable POST verb on static elements (i don’t know how to do and it’s a trick to put up on all the iis i might use. awful)
– remove POST from $.ajaxsetup, adding again to all the $.ajax requests (boring and lengthy)
– replace all $.load with $.get, having to write code to add the resulting html to desired div (again, boring and lengthy).

Any workaround is appreciated.
