routing to specific backend (via a gateway) using a custom header

[miqui]

hi APicraft,

So, we have been tasked to hit a specific backend depending on the value of a custom header. The API is proxied via a gw and the proxy logic will depend on this custom header. So,  my concern is more on a coupling concern (gw logic and the api itself) - what if the API is proxied  by another gw product, etc..etc...

rgds,

Miguel
