I need to do a 301 redirect on a single page. If I just wanted it to work from www.example.com, I would have:
redirect 301 /urisegment1/urisegment2/urisegment3 http://www.example.com/urisegment1/urisegment2/NEWURISEGMENT3
The problem is, users may access http://www.example.com/urisegment1/urisegment2/urisegment3 or sometimes https://www.example.com/urisegment1/urisegment2/urisegment3/ if they have been logged in and access SSL-protected pages. Also I have the site set up locally so I can access it through http://www.example.local/urisegment1/urisegment2/urisegment3
How can I get this to work for all cases?
(That's the end of the question, my current .htaccess file below in case it is relevant. Note it's mostly not my own work, it is drawn from various sources).
