Imbalance LB in "Select different persistence methods"

Hi, iRules: when HTTP_REQUEST { If we are using the App, we should override the default persistence profile We will force the use of a hash for client_ip and x-forwarded-for if { [string tolower [HTTP::host]] eq "app.xyz.com" } { log local0. "Bypassing Cookie Persistence: [string tolower [HTTP::host]][string tolower [HTTP::path]]" If there is an X-Forwarded-For header, use this if {[HTTP::header X-Forwarded-For] != ""}{ log local0. "Using X-Forwarded-For: [HTTP::header value "X-Forwarded-For"]" persist uie [HTTP::header X-Forwarded-For] 600 Otherwise, use Client IP Address } else { log local0. "Using IP: [IP::client_addr]" persist uie [IP::client_addr] 600 } } } Because current result of LB, It's pretty imbalance, and based /Statitics/Local Traffic/Persistence Records, I found www page generated named source address affinity record.
