iRule Not Allowing Server Page To Display

I have the following iRule in place. As you can see I am only trying to change common idle timeouts. when HTTP_REQUEST { if { ([IP::addr [IP::client_addr] equals 172.17.101.60] or [IP::addr [IP::client_addr] equals 172.17.101.149]) and ([HTTP::host] equals "soaprod.corp.unifirst.com") } { log local0. "original timeout: [IP::idle_timeout]" IP::idle_timeout 10800 log local0. "updated timeout: [IP::idle_timeout]" set serverside_idle_timeout 1 } } when SERVER_CONNECTED { log local0. "original timeout: [IP::idle_timeout]" if {[info exists update_serverside_idle_timeout] && $update_serverside_idle_timeout}{ IP::idle_timeout 1802 log local0. "updated timeout: [IP::idle_timeout]" } }

 

If the above iRule is in place I get a "Page coonot be displayed" error when trying to go to url However if I remove the iRule the page displays perfectly. I have double and triple checked the iRule and can find nothing that would be causing this. Any idea?

    Hi UniFirst1,

    you may try this snipped...

    when HTTP_REQUEST { 
    if { (( [IP::addr [IP::client_addr] equals 172.17.101.60] ) or 
          ( [IP::addr [IP::client_addr] equals 172.17.101.149] )) and 
          ( [HTTP::host] equals "soaprod.corp.unifirst.com" ) } then {
        log local0. "original timeout: [IP::idle_timeout]"
        IP::idle_timeout 10800
        log local0. "updated timeout: [IP::idle_timeout]"
        set serverside_idle_timeout 1
    }
}
when SERVER_CONNECTED {
    log local0. "original timeout: [IP::idle_timeout]"
    if { [info exists serverside_idle_timeout] } then {
        IP::idle_timeout 1802
        log local0. "updated timeout: [IP::idle_timeout]"
        unset -nocomplain serverside_idle_timeout
    }
}

    If the error still persist, then take a look to your LTM logfile. In 99,99% of the cases it will raise an TCL error if the iRule is having any issues...

    Cheers, Kai
