.htaccess RedirectMatch regex issue

Question

I'm trying a redirection with this code in my .htaccess file. What's wrong with it?

It runs seamlessly without regex (first line) but no way to execute the redirection with regex on the second line.

RedirectMatch 301 /videos/100067.mp4 http://test.com/video/100067/dfts4555444.mp4

RedirectMatch 301 /videos/^([0-9]+)?$.mp4 http://test.com/video/$1/([a-z0-9]+).mp4

Answer 1

^ and $ match the start and end of a string, respectively.

Something like this should work better:

RedirectMatch 301 ^/videos/([0-9]+)\.mp4$ http://test.com/video/$1/$1.mp4

I have no idea where you are getting the last part of the resulting url from, the dfts4555444.mp4 part. I used $1 to make it work for now.
