i need a referer rewrite condition

Domain somedomain.com is hosting from a server and other his sub-domains (sub1.somedomain.com etc) is hosting from other machines.

I need a RewriteCond for referer.

just wanted to restrict the request that comes except from internal domains and sub-domains.Mean Request will be denied if some one tried to fetch some stuffs like images from his own server.

I have the followings:

RewriteCond "%{HTTP_REFERER}" "!^http://somedomain.com/.*$" [NC]
RewriteRule "\.(jpg|gif|png|txt)$" [F]

what to do if i have the many sub-domains and different (live otherdomain.com) domains, i wanted to allow ?



if i am adding this:

RewriteCond "%{HTTP_REFERER}" "!^http://st1.somedomain.com/.*$" [NC]
RewriteCond "%{HTTP_REFERER}" "!^http://st2.somedomain.com/.*$" [NC]
RewriteCond "%{HTTP_REFERER}" "!^http://otherdomain.com/.*$" [NC]
#RewriteCond "%{HTTP_REFERER}" "!^http://%{HTTP_HOST}/.*$" [NC]
RewriteRule "\.(jpg|gif|png|txt)$" [F]

and using link on st1.somedomain.com

lynx http://st1.comedomain.com/mani/hh.php

then getting this error: message

Warning: file(http://somedomain.com/ma.txt) [function.file]: failed to open stream: HTTP request failed! HTTP/1.1 404 Not
Found in /var/www/html/hh.php on line 3
Warning: implode() [function.implode]: Invalid arguments passed in /var/www/html/hh.php on line 3


hh.php contains:

<?php

echo $html = implode('', file('http://somedomain.com/ma.txt'));

?>

Pl. let me if some other information also needed!

I'm sorry but I don't get your question... can you provide more info? Are you trying to restrict url access? If so you can restrict domains to certain ip address using LIMIT feature.

Thanks for attention !

I need a url condition, that will prevent Hot-Linking of Images and some text file from other websites.

I have many domains and sub-domains.
eg. domain1.com and it's so many sub-domains
domain2.com and so many sub-domain.... etc
etc...

Now i want to only allow my domains and their sub-domains to access these files (Images and text files.)

I did a little practice on this, and at some extent i achieved the goal.. but that is not a correct way to do this.... as i think.


RewriteCond %{HTTP_REFERER} !^http://(.+\.)?(domain1|domain2)\.([a-z.]+) [NC]
RewriteRule .*\.(jpe?g|gif|png|txt)$ - [F]

Is there any way, that Condition will read all the domains and sub-domains dynamically or from text files.

Yes, that is correct way to stop image hot linking. See
Apache prevent hot linking or leeching of images using mod_rewrite howto

my question is, is there any way that Rewrite Condition will read my all domains and sub-domains from a text file or from some other resources, that will fit in condition rather than using OR ( | ) condition in that

RewriteCond %{HTTP_REFERER} !^http://(.+\.)?(domain1|domain2)\.([a-z.]+) [NC]

i have so many domain by different names.

domain1.com
server.com
etc...

about 40-50 domains and sub-domains

No there is no text file or other file to include. You have to write complex task yourself. This is why they hired you to do all config work
