IE fails to send/set custom request headers

[[email protected]…]

It'd be nice to allow custom request headers in AJAX requests.

Here is a patch:

I'd like to vote for the inclusion of this into jQuery ASAP.

There is now a "preprocess" option for $.ajax that allows to set both custom headers and override mimeTypes. IE (5 - 7) seems to fail to set/send custom headers, therefore I leave this ticket open until a solution or explanation is found for that issue.

Renamed "preprocess" to "before" for consistency with form plugin.

The callback is now "beforeSend".

The tests still fail for IE. Using a pseudo-standard header starting with "X-..." doesn't help either.

Seems like this is only a problem in the testsuite, as noone else is reporting this problem.

I'm currently having the same problem in FF. the 'X-Requested-With' header which should be built-in to jQuery is not being sent with the request. I've checked every line of the code and I'm certain the following lines get executed:

1998 Set header so the called script knows that it's an XMLHttpRequest 1999 xml.setRequestHeader("X-Requested-With", "XMLHttpRequest");

I've also tried my own implementation... Add custom header to every call (HTTP_X_METHOD:Ajax) $().ajaxSend(function(a,r,o){ r.setRequestHeader("X-Method", "Ajax"); });

But this also fails...
