Question

i think header is confusing, here is the situation.

i host some video files and want to use on my website. but only on my website. if you realized facebook did this. but we dont have servers like them -nginx i guess-.

finally i want to redirect all requests to a certain page. like that

if someone request that

http://www.blabla.com/videos/1.mpg?hash=12345&expire=1234567

htaccess redirect that request to

http://www.blabla.com/check.php?file=videos/1.mpg&hash=12345&expire=1234567

but also if someone type

http://www.blabla.com/videos/1.mpg

it is also redirect to check.php

http://www.blabla.com/check.php?file=videos/1.mpg

Answer 1

RewriteCond %{QUERY_STRING} ^hash=(.*)$ 
RewriteRule ^(.*)/videos/(.*)$ /check.php?file=videos/$2 [R=302,L,QSA]

Now your rewriteRule will only be applied if query string contains hash=xxxxx

use R=301 if you want users to be redirected permanently
