Irules - Help

Hi,

 

I need some assistance in writing an irule

 

 

for the following requirement for the http requests

 

 

1)Http://xyz.com redirect to "http://www.xyz.com"

 

2)If all the pool members are down - redirect "http://www.xyz.com" or "http://xyz.com" to "http://www2.xyz.com"

 

3)If LB_Failed then fall back to "http://www2.xyz.com"

 

 

Is it recommended to have a single irule defined to match all the three requirements or 3 different irules for each requirements.

 

Pls provide me with an irule definitions.

 

Thanks, Raj
