301 redirect on AJAX -- redirected?

I have an AJAX call to a server endpoint that does a 301 redirect to the same page, but with a trailing slash.

Does the browser follow redirects when called with AJAX or does it ignore them? In my case it doesn't follow them, but I figured it might be something from the server config.

I also had this problem and the suggestion about the trailing slash got me thinking ... I had a rewrite rule in my Web.Config to make everything lowercase and that's what was messing up my AJAX call. I was POSTing to GetResults (which showed up as a 301) and my rewriter (for some unknown reason?) was changing it to a lower-cased getresults GET which resulted in a 404.

Hope this might help someone else.

According to jQuery's API doc (http://api.jquery.com/jQuery.ajax/), async:false (aka. sync mode) does not support cross-domain and dataType: "jsonp" requests.

Maybe this answer is a little bit late but i had the same problem with 301 response on ajax request. The solution was quite simple:

apache rewrite rule is something like this:

RewriteRule ^([^/]\w+)/?$ index.php?%{QUERY_STRING} [L,E=MODULE:$1]

Your XHR-Request url looks someting like this:

/this/is/a/canonical/url + '?param=1&param=2...'

It will lead to the 301 moved permanently if you dont use a direct file call (f.i. *.php) and rewrite to canonical URL (looks like a directory-path without f.i. *.php) instead.

To solve this problem just add a / to your XHR-Request-URL like this:

/this/is/a/canonical/url + '/' + '?param=1&param=2...'

Maybe this will help someone.

If you are using jquery you could look at the questions below to implement it. By default jQuery (and most libraries with Ajax) don't follow redirects by default:
