Rewrite Profile for broken App

Hi,

 

Got a little bit broken application provided by one of our clients that I need to expose.

 

Basic problem is that detects locale from browser and matching URI for it ex: /i18n/original/en-GB/general.json

 

I know this does not work for en-FR language so this URI is not correct. Can somebody help me with developing Rewrite Policy that will: * If somebody will ask for something in /i18n/original/en-FR/ (starting with) this will be rewritten to en-US * Not expert ist that response/request rewrite but all what I want is when my app ask for this I want to return something after search and replace this en-FR to en-US. Because this is always there.

 

Was also told using Rewrite profiles is better than iRules - this is why trying to figure it out.
