Collapsing Lots of URIs into one with 2 Irules

And the one which is attached to the SSL VS:

 

 

when HTTP_REQUEST {

 

 

Do a force redirect anyone access the root

 

Match the Paths to the various applications URLs

 

Re-write the headers so back-end server still thinks it recieving "legacy" client requests

 

Internalapp2 is not a public website and has an additional white list for live and test variations

 

Final piece is to do with that there are two slight variations of the external app, essentially different branding paths to the same location
