React to 303 status code in jquery ( Prevent from redirecting)

when I send requests to a certain server, a 303 response will come, followed by the requested response in combination with a 200 status code. Funny thing is that I only see this on my developer console's network view. When checking the statuscode and response of my $.ajax() request, there will be the response of the second request, as well as a 200 http status code.

The problem is that it seems that the second request is being cached (though 200 status code), and I really need it to be non-cachable. Therefore I'd really like to intervene into the forwarding process that occurs with a http 303 status code. I'd like my jquery function to check for the status code, then send the get request with explicit headers, that tell the server not to cache the response.

Well, I just don't know how to do this, since (as mentioned above) the jQuery.ajax method will respond with the forwarded request's response and status code (200).

Can you help me?

10.3.4 303 See Other

The response to the request can be found under a different URI and SHOULD be retrieved using a GET method on that resource. This method exists primarily to allow the output of a POST-activated script to redirect the user agent to a selected resource. The new URI is not a substitute reference for the originally requested resource. The 303 response MUST NOT be cached, but the response to the second (redirected) request might be cacheable.

maybe I need to somehow prevent the user agent from redirecting himself, so I can do the redirect?

Or is there a way to simply tell the server/browser not to cache the second request from client-side? or to prevent it from redirecting my request? or at least modify the second request before redirecting?

What is status code 303?

The HyperText Transfer Protocol (HTTP) 303 See Other redirect status response code indicates that the redirects don't link to the requested resource itself, but to another page (such as a confirmation page, a representation of a real-world object — see HTTP range-14 — or an upload-progress page).

This is old post, but maybe someone will find this useful.

I have the same issue, and in my case the problem was in the method that was called out using the ajax. The problem was in the redirection that was set in the method. So, based on this, you can't use both ajax and redirect(server side), and i removed redirect() function from method, i everything works as expected. Btw, i am using codeigniter.

Responses in the 300 range are meant to be transparent. AFAIK, web browsers don't expose any of them to javascript. Thus, handling the 303 is not an option.

Have you tried setting the cache property to false in the ajaxSetup? It will append a timestamp to the request, preventing the browser from caching the response. You can also do that manually yourself. The browser should match the first request url to the 2nd response
