NimbostratusI would like to know how to redirect F5 traffic using a iRule when the main URL site displays an specific keyword on the main web page (example: "Maintenance"). Keep in mind that the pool members will still be passing health checks during this time. I would also like to incorporate into this same iRule a redirect when all pool members are down.
NoctilucentTried 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.
NimbostratusThanks 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?
NoctilucentCan't grep maintenance keywords from different vip's URL.
Nimbostratusjhaas 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?
NimbostratusUpdated to prior question:
Here's the new scenario I would like to know if there's a way to perform the following?
I have a F5 VS with (2) pool members that is routing to http://abc.home.com and would like to know if there is a way to create a irule to check the contents of the following site
http://abc.home.com/home/a/b/Offline.html
and if keyword "Offline" is detected on this site to redirect traffic to http://www.google.com
