Question about creating iRules

It is amazing what reading the manuals can do for you. I'm sorry for some of the silly questions. My programmers changed their requirements and now want me to tranlate IP addresses to customer names.

 

 

I'm trying to do this, using matchclass, but I can't seem to get the syntax right.

 

 

when CLIENT_ACCEPTED {

 

set ckname NETWORK_ALIAS

 

if { [matchclass $::Alias_Subnet contains [IP::client_addr] } {

 

set ckvalue ATLAS

 

}

 

elseif { [matchclass $::Test_Subnet contains [IP::client_addr] } {

 

set ckvalue TEST

 

}

 

else {

 

set ckvalue UNKNOWN

 

}

 

}

 

when HTTP_REQUEST {

 

HTTP::header insert $ckname $ckvalue

 

}
