In set_language view, it should be possible to not perform redirect after request is made. Instead, a 204 status code could be returned. While performing a redirect was a reasonable behaviour in old times of HTML apps, for many AJAX applications it may be unnecessary and even uncomfortable if there is no good page become a redirect target.

I'd go even further, if there is no redirect parameter provided just return 204. Do all browsers etc support this properly?!

EDIT:// Thinking about this a bit more: since we change the language we have to redirect, how else would we change the UI?

The project I’m currently working on uses Django as an API backend and AngularJS application as a frontend client to this API. The UI localization is done using Mozilla’s L20n project and language changing is done on-the-fly, without reloading the page. However, there are still some parts of the site which use Django templates (like password change form), so making an AJAX call to set_language is still necessary, but they are loaded using iframes, so there is no need to perform a redirect.

Not performing a redirect when it is not explicitly requested seems tempting, but it will be backwards incompatible with the current behaviour – I guess there may be a significant number of sites which rely on the fact that set_language redirects them to the previous page (captured from the referer header). Maybe we should check request.is_ajax() and if it is true, omit the redirect unless next parameter is set? For old-style HTML websites it may be still a coarsely correct assumption that a redirect needs to be performed after changing the language. That way we can resign from introducing the new no_redirect parameter.

204 status code seems to be supported by browsers, according to .
