Can't fix Jump to post isn't maintained after login

[refael]

For the example, assume there's a forum that is open only for logged in users.
Now someone wants to show me a post:
http://example.com/threads/test.5/#post-20

This should bring me to post 20.
I open this link as a guest, which means I can't see this content. So I log in, then I redirected to
http://example.com/threads/test.5

So I actually won't be jumped into the post that I needed to see.

The hash is never actually exposed to the server, so in the general case we can't really do anything about this. We simply redirect to the page you were on (as told to the server).

Would you consider to workaround that with js?
I guess the simplest way would be to add a hidden input, and set the value to the full url (or just the hash part) using js.
