重写URL，从子域到另一个子域

Question

Im try find good solution to hide real streaming url, im try with php but have problems with stream in that way like

http://site.com/player/stream.php?p=[file path]&f=filename.flv&t=<? echo md5(session_id().$_SERVER['REMOTE_ADDR'])?>

Maybe rewrite url with htaccess is better solution? something like this

http://media.site.com/videos/0412/125843213/125843213.flv [org. file]

rewrite to

http://s1.media.site.com/0412/125843213.flv

.. any idea how to make this? or maybe is better to back on php...?

Answer 1

In your htaccess file in the root directory, or from your apache configuration:

RewriteEngine On
RewriteBase /
RewriteRule ^videos/(\d+)/(\d+)/(\d+)\.flv$ http://s1.media.site.com/\1/\3.flv [R=301,L,QSA]

Having said that, once you have a rewrite, then your 'real url' that you want to hide has become the rewritten url. You will be able to access the file using either url. Basically, one of the urls to access the file will still be accessible by any users, so it's not any more secure.

Also, because of the host change, you will be sending 2 times the number of requests to your servers.

Good reasons to use rewrite:

• SEO
• Single entry point (like in CakePHP, CodeIgniter, etc - index.php)
