jQuery AJAX call to Web API returns Status 240 when the API Controller Action returns BadRequest()

Question

We have a Web API that has an action that returns BadRequest() which is a 400.

the call to the API looks like this:

$.post("/api/controller/action", {test:"Bad data"}).success(function(data){

    console.log(data)

});

the API Controller Action method returns an IHTTPActionResult of BadRequest("Invalid data recieved"); The Chrome inspector verifies the return was a 400, Fiddler verifys 400, but jQuery runs its success method and console.log(data); shows us that data.status = 240.

I do not think its just jQuery, because AngularJS's $http service does the exact same thing.

I have the same exact thing, Postman returns STATUS 240 Bad Request. Which seems like a contradiction. Code 2xx means success but status text says "Bad request". Only on Chrome/Firefox. IE returns it correctly. — Grzegorz Kaczan, Jan 29 '15 at 16:24
Update: I curl'ed it and it correctly returns status code 400. — Grzegorz Kaczan, Jan 29 '15 at 17:48

I got this fixed by removing all suspicious extensions from both Chrome and Firefox. I realized i had Trovi installed, which is a virus causing some redirections (apparently). So turned out to be 3rd party software fiddling with my browsers.

Same Postman call as before now correctly shows me 400 Bad Request instead of 240.
