Hi @hering

On a multilingual website I have a "login" menu item (com_users, not using the module).

hmm i didn't test on a multilingual site but the code for the redirect is in the Login Modul (mod_login):
1. Here we request the retrun url:
https://github.com/joomla/joomla-cms/blob/staging/modules/mod_login/mod_login.php#L18
2. Here we create the return url:
https://github.com/joomla/joomla-cms/blob/staging/modules/mod_login/helper.php#L22-97
3. Here we add it to the form:
login: https://github.com/joomla/joomla-cms/blob/staging/modules/mod_login/tmpl/default.php#L116
logout: https://github.com/joomla/joomla-cms/blob/staging/modules/mod_login/tmpl/default_logout.php#L28

So you need to use the mod_login to login and to logout to use the function.

What do you use if not the Core login module (mod_login)?

Thanks a lot for your comment.
I use a menu item that points to com_users (User Manager > Login Form). That allows creating a login form without the necessity to first create a page that is only required as a place where we can then position the login module (and this once for each language).

If redirection is only possible with the module and not with the component, then it would be less confusing if the the option to specify redirection URLs was removed from the component.
To do so, it would be necessary to change components/com_users/views/login/tmpl/default.xml and remove the fields "login_redirect_url" and "logout_redirect_url".

However, I think it would be nicer to have redirection work in the component just as the user interface suggests, because it seems more straight forward to me creating a menu item that goes directly to a login form than creating a menu item that points to something only to have a place where I can then position a login module. Just my 2¢.

hehe thanks @hering I don't know that com_users has this view. I will have a look into it.

@hering what do you test? A external or a internal link? For me internal links like http://www.example.org/index.php/latest-articles works ok. But if i what to return to a external site like http://www.joomla.org It don't work.

I would vote for changing the behavior on the com_users login form to the behavior that we have on mod_login that only internal urls are allow and use a dropdown to select it.

I have a workable solution. See here #4208

I did only use internal URLs (external URLs are not supposed to work as per the GUI), with or without the protocol prefix and starting from root of relative URLs e.g. "/target/from/root" or "http://domain/target/from/root" or simply "relative/target/" but I never tested with SEF = 0 and "index.php" URLs as JRoute might use them.
Have to check that out. Thanks again.

Edit:
I forgot to mention the language in the URLs, so actually I specified URLs like
"/target_from_root/en/" or "http://domain/en/" or simply "en/" where "en" stands for the English version of the page.
Specifying a no-SEF URL such as http://domain/index.php?option=com_content&view=article&id=22&Itemid=114&lang=en does indeed work for both login and logout.
The only catch with this solution is that the no-SEF URL is displayed as such in the browser's location bar no matter wether SEF is activated or not. The login redirect URL seems not to be run through JRoute.
Thanks zero-24 for that idea.

@hering can you have a look into this #4208 (comment) It should fix your issue.

Here (#4208 (comment)) you can find some instructions how you can test it. Please let me know if you need more help or instructions.

Thanks
