enhancement: PREFIX 'allowed_prefix' security filter

[robsoncombr]

Hello,

I think very important the TLD security implementation, however in my case I use PREFIX, on my local/dev environment I have http://dev.domain and on my production I have http://www.domain I would like to be able to allow/block usage by PREFIX so I could set 'dev' in config file and it would work only in my development environment.

Hope this is interesting and implemented.

Thank you,

Robson

I think this might be covered in #14?
