Hash persistence based on true-client-IP

One update already, I need to change the first line to use HTTP_REQUEST. When I was writing this, I was confusing this application with another one I've been working on that balances Windows RDP traffic (port 3389). But this rule is absolutely for HTTP traffic.

 

 

New code:

 

 

===================================================

 

when HTTP_REQUEST {

 

check for True Client IP header:

 

if { [HTTP::header exists "True-Client-IP"] } {

 

 

chuck the value into a variable

 

set tcip_header [HTTP::header "True-Client-IP"]

 

 

or throw in a default value, if the header isn't there

 

} else { set tcip_header "1.1.1.1"

 

}

 

}

 

 

select node by hashing True-client-IP value and pulling that item from the node list from the pool

 

set picked [lindex [active_members –list app_http_pool ] [expr [md5 [$tcip_header]] % [active_members app_http_pool]]]

 

 

send traffic to the selected pool member

 

pool app_http_pool member [lindex $picked 0] [lindex $picked 1] }
