Tried to write iRule based on the question. Let us know if any question.
when HTTP_REQUEST {
if { [active_members [LB::server pool]] == 0 } {
HTTP::redirect "http://www.google.com" }
}
when HTTP_REQUEST_DATA {
Define a string-type datagroup called dg_blocked containing words to be "Maintenance"
if { [matchclass [HTTP::payload] contains dg_blocked] }{
HTTP::respond 302 Location "https://www.google.com" }
}
For general payload examination, payload collection is limited by memory allocation constraints to a 32MB maximum.

Thanks for the response back jhaas now I have another question. Is there a way in the iRule/datagroup to look look for this keyword "Maintenance" at a specific URL that is different than what the F5 VS is pointing to?

Can't grep maintenance keywords from different vip's URL.

jhaas so I wouldn't be able to do the following?
Current F5 Pool routes to abc.com:1009
I would like to check location 123.com for keyword "Maintenance" and once this site contains this keyword I would like to redirect F5 traffic to xzy.com:1009/Maintenance.htm?
If I understand this correctly the keyword "Maintenance" would need to reside on site abc.com:1009 in order to perform the redirect....is this a correct assumption?
