Have a redirect rule which only triggers on certain conditions such as a referer header or ip range

[brendanheywood]

This would be much better done after #1 so each redirect has its own form and record

• if logged in / not logged in
• if a header matches eg referer
• if the client ip matches a range
• if a cookie is set -> also set this cookie if other triggers fire
• also be able to declare a rule in config which is appended and readonly
