I'm rebuilding a site in wordpress. The existing site has unique profile pages with the URL of the form www.domain.com/b/ch/2lZl.htm
The new system will have unique profile pages of the form www.domain.com/profile/bch2lZL (where bch2lZL is the unique user ID).
What I need to do is get this unique ID and load the page www.domain.com/tracker/public/user/bch2lZL which will do the processing (load in content for this user etc) but don't want the URL to change from www.domain.com/profile/bch2lZL.
I'm hoping this can be achieved with a htaccess redirect where it can load the user can go to the domain www.domain.com/profile/bch2lZL and be presented with the page which is actually at www.domain.com/tracker/public/user/bch2lZL without a change in the URL
Is this possible? And how can I do it?
Cheers in advance
