When making XHR requests, can you please set the Accept header? It's currently not set, meaning it defaults to *

Server side frameworks use the Accept header to determine how a request should be handled. For example, Spring Security will return HTTP 401 instead of redirecting to a login page is authentication is required.

I believe that these should be the values for the requests:

• /info should have Accept: application/json
• /xhr should have Accept: application/json
• /xhr_send should have Accept: text/plain
• /xhr_streaming should have Accept: application/javascript
• /eventsource should have Accept: text/event-stream

In some cases, it's not possible to do set the Accept header (such as when using XDomainRequest, iframes, or jsonp). But it should be set appropriately whenever it is possible.
