iRule to alert on hotlinking

As far as the header Referer goes, this header would include the full URL, including protocol. Just like you would see it in the URL field in the browser. For example:

 

http://www.example.com/this/that/theother.jsp

 

 

So, since you are using the URI::host method, this would extract the host and your refer_host variable would be set to www.example.com, if we follow the prior example.

 

 

So, if you were using starts_with, you would have to match all possibilities at the beginning of the URL. ie. www.example.com, example.com, goodstuff.example.com, etc.

 

 

If you are just interested in a domain (example.com), then I would change the operator to ends_with and just specify example.com as a string or put it in your class.
