Hot Link Protection via .htaccess

spasticdonkey · Posted: Mon May 07, 2007 6:24 pm

Well I have setup hotlink protection in .htaccess and it works, but there was one feature I couldnt quite get working. I am trying to substitute an image of my choosing, when someone hotlinks to one of mine

Code:

RewriteEngine on
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://mysite.com/.*$ [NC]
RewriteCond %{HTTP_REFERER} !^http://mysite.com$ [NC]
RewriteCond %{HTTP_REFERER} !^http://www.mysite.com/.*$ [NC]
RewriteCond %{HTTP_REFERER} !^http://www.mysite.com$ [NC]
RewriteRule .*\.(gif|jpg|mp3|css|js)$ http://www.mysite.com/angryman.gif [R,NC]

Is hotlink protection itself blocking the display of the image? Or have I made a mistake in there somewhere?

Just to warn others, one mistake I made at first was not including the address without the www too. Since my site works either way, I was blocking images from my own site Sad

this should be enough i think..

RewriteCond %{HTTP_REFERER} !^http://(www\.)?yoursite.com(/)?.*$ [NC]
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{REQUEST_URI} !/info/ [NC]
RewriteRule \.(png|gif|jpe?g)$

[NC,R,L]

the folder info is where to put abuse image...
keep any used image small,prefered a few hundred bytes.

thanks I'll give it a try. Still recovering from a total pc meltdown so might be a bit. I also wanted to block
js flv css wmv mp3 files but assume I would do so on another line, like so?

Code:

RewriteCond %{HTTP_REFERER} !^http://(www\.)?yoursite.com(/)?.*$ [NC]
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{REQUEST_URI} !/info/ [NC]
RewriteRule \.(png|gif|jpe?g)$ http://www.yoursite\.com/info/abuse.png [NC,R,L]
RewriteRule \.(js|css|flv|wmv|mp3)$ [NC,R,L]

i assume you were breaking the code with the "?" (jpe?g) any other breaks? Also does doing it this way remove the need to list the allowed domains by both

and yoursite.com ?

also, does this work if you draw the replacement image from another server/domain?

thanks Smile

I am not taking over the thread... Wink

I just want to explain the above a bit (you cannot take the teacher out of me...):

The "e?", actually, is basically allowing this to match on both "jpg", without the "e" notice, and also "jpeg". That's all.
