as andreyp mentions these are good ideas, however the commands to add to .htaccess he specifies will do abosolutely no good because the are commented out with the #

Basically if you add a # to your .htaccess each line with the # means to ignore it and do no good. So I don't know why this was even posted or why it wasn't clarified that you need to remove the # to do any good and to take affect. Guess everyone is supposed to know that by default.

#RewriteCond %{QUERY_STRING} ^http [OR]
#RewriteCond see more %{QUERY_STRING} ^.+www\. [OR]
#RewriteCond %{QUERY_STRING} ^.+https [OR]
#RewriteCond %{QUERY_STRING} ^.+ftp
#RewriteRule .* - [L,F]
#RewriteCond %{HTTP_USER_AGENT} ^libwww [OR]
#RewriteCond %{HTTP_USER_AGENT} ^Wget
#RewriteRule .* - [F]

#RewriteCond %{QUERY_STRING} (.*)=http(.*) [NC,OR]
#RewriteCond %{QUERY_STRING} (.*)urlx=(.*) [NC]
#RewriteRule ^(.*) - [F]

and even php_value allow_url_fopen 0 :-)

I haven't tested it fully you will havet to remove the:
and even php_value allow_url_fopen 0 :-)

And all #'s to work at all. If you were to use this command in .htaccess it would be more like:
RewriteCond %{QUERY_STRING} ^http [OR]
RewriteCond %{QUERY_STRING} ^.+www\. [OR]
RewriteCond %{QUERY_STRING} ^.+https [OR]
RewriteCond %{QUERY_STRING} ^.+ftp
RewriteRule .* - [L,F]
RewriteCond %{HTTP_USER_AGENT} ^libwww [OR]
RewriteCond %{HTTP_USER_AGENT} ^Wget
RewriteRule .* - [F]

RewriteCond %{QUERY_STRING} (.*)=http(.*) [NC,OR]
RewriteCond %{QUERY_STRING} (.*)urlx=(.*) [NC]
RewriteRule ^(.*) - [F]

all your other dolphin .htaccess code would follow here!!

I wouldn't be surprised if some of this made certain thing not work specifically your share files in your media locations such as:
when you click on your share link in photo, music, and video gallery in the actions menu. The above code will block it. Is this all bad I don't know. But it will piss some off. Either that if you use the above code you will have to remove the share link to do away with it.

The code I use is similar to boonex guys except mine already has the #'s removed so they do work:
Options -MultiViews
Options -Indexes
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{HTTP_REFERER} ^(.*)(<|>|'|%0A|%0D|%27|%3C|%3E|%00).* [NC,OR]
RewriteCond %{QUERY_STRING} ^http [OR]
RewriteCond %{QUERY_STRING} ^.+www\. [OR]
RewriteCond %{QUERY_STRING} ^.+https [OR]
RewriteCond %{QUERY_STRING} ^.+\.txt [OR]
RewriteCond %{QUERY_STRING} ^.+ftp
RewriteCond %{QUERY_STRING} ^.*(;|<|>|'|"|\)|%0A|%0D|%22|%27|%3C|%3E|%00).*(/\*|union|select|insert|cast|set|declare|drop|update|md5|benchmark).* [NC,OR]
RewriteRule .* - [L,F]
RewriteCond %{HTTP_USER_AGENT} ^libwww [OR]
RewriteCond %{HTTP_USER_AGENT} ^.*(libwww-perl|curl|wget|python|nikto|scan).* [NC,OR]
RewriteCond %{HTTP_USER_AGENT} ^Wget
RewriteRule .* - [F]


I also block a number of things such as .htaccess, so you can't view my .htacess files, I also block certain countries. I do block peridic file, I also block file types that can be uploaded to audio video like php, txt, vbs, cgi, pl, etc. you name it. Anything that is out of the ordinary can't even be uploaded to dolphin/ray folders to begin with.

Good luck.
