Apache Mod Rewrite does not rewrite file name - apache

Question

i have the following problem:
On the download dialog on each browser it displays me only the dot extension filename
like .divx
But i want the full name eg
http://example.com/14558/.divx rewrites to 14558.divx and not onyly .divx
I want see on every browser dialog the number and the extension.
like 14558.divx
How i can solve this problem ??
RewriteRule ^([0-9]+)/.divx$ $1.divx
RewriteRule ^([0-9]+)/.mkv$ $1.mkv
RewriteRule ^([0-9]+)/.avi$ $1.avi
Current Configuration:
RewriteRule ^([0-9]+)/\.(divx|mkv|avi)$ /$1.$2

Answer 1

Your rewriterules seem ok... err well maybe it's the backslash. By the way you could optimize in a nicer way (not tested):
RewriteRule ^([0-9]+)/\.(divx|mkv|avi)$ /$1.$2
But the only way to solve your problem (= show the whole filename) is to make a full redirect to a URL that has the full filename.
So in your case redirect would mean these rules:
RewriteRule ^([0-9]+)/\.(divx|mkv|avi)$ $1.$2 [QSA,R=301,L]
And that implies that the URLs like "14558.divx" and "1526.mkv" have to be valid and return the file.
Two hints:
Please try to use the RewriteLog directive: it helps you to track down such problems:
# Trace:
# (!) file gets big quickly, remove in prod environments:
RewriteLog "/web/logs/mywebsite.rewrite.log"
RewriteLogLevel 9
RewriteEngine On
