Solution 2

to do this using query string
Why query string for such thing? Necessary?

Query string way:
Add the lastPage in the querystring. Once the singup is done, based on the lastPage querystring, form the correct url and then redirect there.

Now, query string is not just the only way. There can be lot more ways to do the same. You can use global object, other stage management techniques including query string.

For example, for session, store the page url in a session before moving to the signup page. Once singup is done, get the url from there and use it to redirect user back to the old one.

Solution 3

You can create a session call it source and reset the page name it everytime you open one, when u leave to your distination you can check the session and know where the request came from. it is one way of doing it but i think there's another way using javascript.
