Unable to identify HTTP header variable for pool redirection

Correct...It should have been on the HTTP_REQUEST. I need to load balance the initial client request, which would not have the HTTP header "datacenter" present. The server inserts the HTTP header "datacenter" 01 or 02 in the response for the client's subsequent request to be used by the i-Rule and returned to the same data center. I modified the rule to add logging;

 

 

when HTTP_REQUEST {

 

set LogString "Client [IP::client_addr]:[TCP::client_port] -> [HTTP::host][HTTP::uri]"

 

log local0. "============================================="

 

log local0. "$LogString (request)"

 

foreach aHeader [HTTP::header names] {

 

log local0. "$aHeader: [HTTP::header value $aHeader]"

 

}

 

log local0. "============================================="

 

 

if { [HTTP::header "datacenter"] eq "01" } {

 

pool PROD-ITA-9045-BILLERICA

 

log local0. "$HTTP::header"

 

} elseif { [HTTP::header "datacenter"] eq "02" } {

 

pool PROD-ITA-9045-WINNIPEG

 

log local0. "$HTTP::header"

 

} else {

 

pool PROD-ITA-9045

 

}

 

}

 

 

I think it may be working but I am only directed to datacenter-01, which may be a limitation of my SOAPUI client.

 

 

Could I not simplify this using universal persistence and a simple i-Rule?

 

when HTTP_REQUEST {

 

persist uie [HTTP::header datacenter]

 

}
