Hello,
First of all, thanks to Michiel for making great software and keep
up the good work :) Well, I'm using Mathopd since about 2 months and I'm
very happy with it except bandwidth eaters. I've checked mailing-list
archive and googled but couldn't find ready-made solution or patch to
prevent hotlinking/remote linking. So, I've written small patch checking
referer information for requests. You can find path file and example
configuration file at http://www.hido.net/projects/mathopd I've added two
new configuration directives. These are:
EmptyReferer
Type: flag
Argument: on/off
Default: on (allow empty referers)
Returns: 403 Forbidden
Example: EmptyReferer off (disallow empty referers)
Allow (on) or disallow (off) empty referers.
RefererMatch
Type: list
Argument: blank space seperated domain/host/ip list.
Default: empty
Returns: 403 Forbidden
Example: RefererMatch { domain.com static.domain.com 127.0.0.1 }
Server checks request referer header. If none of them matches, it returns
403 Forbidden message.
Let me know if you find any errors or ideas, thoughts ;)
Thanks again,
Hidayet Dogan
