I am not able to figured out how to achieve this content switching. is it even doable?
let's say I have this URL /blah?x1=5&x2=-5&y1=-1&y2=50 I want to go to a different set of backends if x1<0, y1<0 -> backends set 1 x1<0, y1>0 -> backends set 2 x1>0, y1<0 -> backends set 3 x1>0, y1>0 -> backends set 4 I have not been able to figure this out.
