I have a web interface that does long polling, ie every 10 seconds it updates some statuses on the webpage using an AJAX request on an interval. I am able to, on some condition, return a 303 redirect to "kick" the user from the page. It doesn't seem to work. Chrome/FireFox.

Looking at Chrome's Network tab

Browser opens page
Browser is requesting JSON data every 10 seconds
On next request, instead of a 200 with JSON data, a 303 is returned
The page to be redirected to appears as a request (200, xhr) but the browser does not redirect. It just carries on.

The 303 appears with the following

Connection: close
Content-Type: text/html
Location: /kicked

The next request is immediately the kicked page, but it's in an XHR request instead of the browser redirecting there.

You need to pass the additional parameters `Location` to the header call. – demkovych Dec 19 '19 at 14:56
I do. It is set. – errno_44 Dec 19 '19 at 14:58

You expect the browser to redirect on an XHR call??? The page is not going to update since it makes no sense for some XHR call to effect the page. You would have to build logic into your XHR response handler to do the redirect. – epascarello Dec 19 '19 at 15:05

@epascarello Yes that's what I expected. – errno_44 Dec 19 '19 at 15:09

Well that is not what happens. The request changes, not the page. – epascarello Dec 19 '19 at 15:19
