O, great!
I never presumed that my request would need to get such an elaborate treatment. I initially thought that it could have been handled by JD2's Basic Authentication module, but now I understand that's not so. I tried that, but it failed. I then presumed that I might have done something wrong. That's why I posted my request. Do you have any idea how long it will probably take for this new plugin to be ready? And how is this plugin going to work with a login procedure?
