mod_auth_form and proper redirection after login

[Thomas Eckert <thomas.r.w.eckert@xxxxxxxxx>]

Using mod_auth_form, when a user tries to access a URL and is 'interrupted' by the form based login, how do I pass on the original URL to the form html or to the AuthFormLoginSuccessLocation directive, so I can redirect the client - upon successful login - to the URL where she wanted to go to.

At

 http://httpd.apache.org/docs/current/mod/mod_auth_form.html#authformlocation

I didn't find info on dynamically setting the value of AuthFormLoginSuccessLocation or using AuthFormLocation for this purpose. Is there a way to do this with 2.4.4 (or possibly 2.4.6) ?
