iRule not hitting default pool?

it could be because you are searching on http::path, but im not 100% about this. But i have made a suggestion, that takes a slightly different approach:

            when HTTP_REQUEST {
              if { [string tolower [HTTP::uri]] starts_with "diagnostics"} {
                pool pool_group2
                persist source_adr 255.255.255.255 1800 
                  }
             else { pool pool_group1 
              }
            }

Hi phipse,

you iRule looks absolutely valid^^

For testing purposes you may try to the iRules below and then take a look to your logfiles...

Test1: Forwarding every request to pool_group1

when HTTP_REQUEST {
    log local0.debug "iRule executed..."
    pool pool_group1
}

Test2: Same as your iRule with added logging

when HTTP_REQUEST {
    log local0.debug "Debug: iRule executed..."
    switch -glob -- [HTTP::uri] {
        "/diagnostics/*" {
            log local0.debug "Debug: Hit the /diagnostics path."
            persist source_addr 255.255.255.255 1800
            pool pool_group2
        }
        default {
            log local0.debug "Debug: Hit the default path"
            pool pool_group1
        }
    }
}

Cheers, Kai

add the following to the irule to see what are we getting back from the server

when HTTP_RESPONSE {

log local0.debug "server Status respose [HTTP::status] if you get 301 or 302 is a redirect, 4XX are authentication and page not found, 200 good respose from the server"
log local0.debug "Http::header [HTTP::header names ] "
log local0.debug "header location [HTTP::header Location]"

}
