Intermediate iRules: Handling Strings

How to construct URI path redirection based on dynamic header values received in an API call. For instance abc.google.com receives these header values:

country=unitedstatesofamerica

state=florida

city=tampa

 it should redirect to another VIP (def.google.com) based on those header values as shown. In this case $ is a delimiter in the URI path.

https://def.google.com$country=unitedstatesofamerica$state=florida$city=tampa

Thanks would appreciate any help in composing this irule.
