CSS11501 - Content Failover

I have a requirement to setup some sort of failover with regards to a web filter server. We have 2 web filters which are setup to load-balance for any http traffic to any web site. However some web sites don' respond well to this and so we have an entry like the following:

content test

vip address x.x.x.x

add service web1

protocol tcp

port 8002

url *//*.bbc.com/*"

active

Other rule is:

content All

vip address *.*.*.*

add service web1

add service web2

protocol tcp

port 8002

url "/*"

active

So when the service to web1 goes down then any traffic going to http://www.bbc.com fails and we have to manually put the other server 'web2'in the content test.

There must be a better way to do this, anyone any ideas?

Cheers

James

Hello,

Not sure I understand your problem, but here is what I think you could do.

I assume you want to have only web1 as being used for loadbalancing for your content test, and only have web2 active when web1 is unavailable.

You can configure web2 as a sorryserver.

add this in you content test:

primarySorryServer web2

This will make web2 kickin from the moment web1 is down.

HTH,

Dario
