How to manage a redirect request after a jQuery Ajax call

Answer 2

Based on this answer: https://stackoverflow.com/a/8752354/698289 I found the following code to be very useful:

$('body').ajaxComplete(function (e, xhr, settings) {
    if (xhr.status == 200) {
        var redirect = null;
        try {
            redirect = $.parseJSON(xhr.responseText).redirect;
            if (redirect) {
                window.location.href = redirect;
            }
        } catch (e) {
            return;
        }
    }
});

Then you just provide JSON such as the following:

{redirect: '/redirect/to/this/path'}

And the ajaxComplete will make sure to redirect the browser.

Be mindful that $.ajax('complete') triggers AFTER $.ajax('success') or $.ajax('error')

Answer 3

I consider this to be a server-side issue, and not client-side. The browser is correct not to follow redirections to http when it makes ajax request by https, as that would be a security flaw.

I realized I was using relative paths, such as HttpResponseRedirect('/path/to/'). On some layer, that url was prepended with the http:// prefix and that was what the browser received: http://example.com/path/to/

You must ensure that the Location gets sent in the response header with a full path, including the https://.

Answer 4

Turns out a bug in the redirect code caused the redirect to go to http:// while the page that was requested was https://. That makes the browser refuse to follow the redirect.
