Sending basic auth to "backend" servers

[jrhodes]

Just one follow up question after some testing. Is there a way to split on a
per request basis?

So say 10 backend servers each with unique authorisation headers set up,
then have each single incoming request RR to each:

Incoming http request 1 -> backend1
Incoming http request 2 -> backend2
Incoming http request 3 -> backend3

And so on...

Thanks!
