Redirecting hosted sites on availablily (not servers)

Yes, separating the ports would make it easier to differentiate, but what we are saying is that even if they run on the same port, as long as they are in different pools with different monitors, one going down won't affect the other. You would still need to use an iRule as you said to select a pool based on the domain name.

 

 

So in your example:

 

 

cat_pool could have 10.0.0.1:80 and 10.0.0.2:80

 

dog_pool could also have 10.0.0.1:80 and 10.0.0.2:80

 

 

you would use a different monitor on cat_pool vs. dog_pool, and if 10.0.0.1:80 fails in the cat_pool, it would not bring 10.0.0.1:80 down in dog_pool.

 

 

Of course if you use different ports, then you can do the same thing without relying on host headers at the server.
