SORRY SERVER

mbaylis · ‎01-16-2009

Hi,

I have question with regards to the sorry server feature. Its says in the cisco docs that this feature can not be used in load balancing.??

We have 2 11500 which are working in an active backup state via vips. We have 2 web servers in the environment.

I want to achieve this, say for instance both the web servers are down, can we redirect any further client requests to a sorry server or something to inform clients the server is down for maintenance??

can anyone help please or point me in the right direction

thanks in advance

I don't know about CSS, but we do exactly what you want to achieve on ACE.

Just look up the sorry server in the CSS config guide.

The 11500 directs content requests to the primary sorry server only when all the other services (In your case the two web servers) are unavailable.

Following is an example with two web servers & one Sorry server. If CSS detects both web servers as unavailable then all new requests will be forwarded to "sorry server"

service web-server1

ip address 10.1.1.1

keepalive type tcp

port 80

active

service web-server2

ip address 10.1.1.2

keepalive type tcp

port 80

active

service sorry

ip address 10.1.1.10

keepalive type tcp

port 80

active

content xyz

vip address 20.20.20.20

protocol tcp

add service web-server1

add service web-server2

primarySorryServer sorry
