Redirect match country and string not in url

I'm using a datagroup like below and the Irule like below. I'm trying to add a statement where if it matches the country australia and doesn't have pid=search in the url, redirect to x else redirect to y. I've tried writing the if statement like this 

if 
{ $redir ne "" } and { not ([HTTP::uri] contains "pid=search")}
and it barfs on me. Any help would be appreciated.

Irule

when HTTP_REQUEST {
    set redir [class match -value -- [whereis [IP::client_addr]] contains country-redirect]
    if { $redir ne "" } {
        HTTP::redirect $redir
    }
    else {
        HTTP::redirect "http://default.example.com/"
    }
}

}`

Datagroup

ltm data-group internal country-redirect {
    records {
        AU {
            data http://www.example1.com/
        }
        CR {
            data http://www.example2.com/
        }
        MX {
            data http://www.example2.com/
        }
        UK {
            data http://www.example1.com/
        }
        US {
            data http://www.example1.com/
        }
    }
    type string
}

    to do list we add secodary URL for each country. firstly, modify iRule like that:

        when HTTP_REQUEST {        set countryCode [whereis [IP::client_addr]]        if {[HTTP::uri] contains "pid=search"}        {            append countryCode "2"        }        set redir [class match -value -- $countryCode contains country-redirect]        if { $redir ne "" }         {             HTTP::redirect $redir         } else {             HTTP::redirect "http://default.example.com/"         }     }

    add a secodary url for each country in the data group: 

    
ltm data-group internal country-redirect { records { AU { data http://www.example1.com/ } AU2 { data http://www2.example1.com/ } CR { data http://www.example2.com/ } CR2 { data http://www2.example2.com/ } MX { data http://www.example2.com/ } MX2 { data http://www2.example2.com/ } UK { data http://www.example1.com/ } UK2 { data http://www2.example1.com/ } US { data http://www.example1.com/ } US2 { data http://www2.example1.com/ } } type string }

    Hi Dean,

    you may take a look to the two iRules below. They are outlining two different coding styles to achive what you've asked for...

    "AND NOT with NE" Syntax

    when CLIENT_ACCEPTED {
    if { [set country [whereis [IP::client_addr]]] eq "" } then {
        set country "empty"
    }   
}
when HTTP_REQUEST { 
    set redir [class match -value -- $country contains country-redirect] 
    if { ( $country eq "AU" )  and 
         ( $redir ne "" ) and
         ( [URI::query [HTTP::uri] "pid"] ne "search" ) } then {
         Do whatever you want...
    } elseif { $redir ne "" } then {
        HTTP::redirect $redir 
    } else {
        HTTP::redirect "http://default.example.com/" 
    } 
}

    "AND with EQ" Syntax

    when CLIENT_ACCEPTED {
    if { [set country [whereis [IP::client_addr]]] eq "" } then {
        set country "empty"
    }   
}
when HTTP_REQUEST { 
    set redir [class match -value -- $country contains country-redirect] 
    if { ( $country eq "AU" ) and 
         ( $redir ne "" ) and not 
         ( [URI::query [HTTP::uri] "pid"] eq "search" ) } then {
         Do whatever you want...
    } elseif { $redir ne "" } then {
        HTTP::redirect $redir 
    } else {
        HTTP::redirect "http://default.example.com/" 
    } 
}

    Cheers, Kai
