There are a couple ways to do it.
1. In your login code, use
xdmp:get-request-header("Referer", "")
to fetch the value of the page from which the user came, then use that
value in the redirect.
2. Even better (as not all browsers send the Referer header you want):
in the code that redirects to the login script, set a session field
value (xdmp:set-session-field()) which can then be used by the login
script, with xdmp:get-session-field().
In either case, you may also need to use xdmp:get-request-field()
to fetch the URL parameters.
