We have implemented a new security
setting to prevent hotlinking contents from other sites and tighten
your entire site security.
"Hotlinking" is direct linking to a web
site's files (images, video, etc.). An example would be using an img
tag to display a JPEG image you found on someone else's web page so it
will appear on your own site, eBay auction listing, weblog, forum
message post, etc.
Let's say if someone hotlinks your content with the link http://yourdomain.com/xxx
in another domain and the firewall alert will get this alert. At the
same time, if you have one site make uses contents directly linked from
other site which owned by yourself from our server, you will also get
this alert as well.
The security setting will also block HTTP headers with strange characters. If your site is password protected and the password is too simple (e.g. "password"), it will be blocked, too.
To change the setting, you may login your Hosting control panel -> Security -> Security Guard, to do so.
