Help tweak this .htaccess code

[nontekkyguy]

I am using .htaccess in addition to certain permission settings to control how visitors access my gallery. Here is one line I tried which points to an image on my server.  I use the following code:

Code Select Expand

<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://([-a-z0-9]+\.)?josefaro\.org[NC]
RewriteRule .*\.(zip|mp3|avi|wmv|mpg|mpeg)$ http://www.josefaro.org/images/fisheyedfool.jpg [R,NC,L]
</ifModule>

to stop that pesky hotlinking business. Does anyone see any way to enhance this code. So far it doesn't seem to work in every case. In fact I'm able to go to properties of the enlarged image, grab the location link, post it in a forum and see the image.

this will only work for image files... cause media player doesn't send a referer header. For movies you'll need to use another attempt

scripts like these possibly may protect you

or you may force users to visit a html page before you let apache serve the content using a cookie

this htaccess needs to go in your content directory (where your movies are, no html, php in there please)

Code Select Expand

RewriteEngine on
RewriteCond %{HTTP_COOKIE} !(^|(.+;)*)id=valid(;.*|$)
RewriteRule .*$ http://www.yourdomain.com/hotlinking.html

on the html, php where you link to the content you need to set the cookie eg with something like)

Code Select Expand


<SCRIPT language="JavaScript">
  document.cookie = "id=valid; path=/"
</SCRIPT>


I haven't tried for coppermine... but it should be enough to put

Code Select Expand

  document.cookie = "id=valid; path=/"
into scripts.js
