client connection persistence using an irule

Hi,

You can use this irule. Replace the header name to the name the reverse proxy is inserting.

# Name: persist_xff_uie
#
# To be used with UIE Persistence Profile
#
# Checks HTTP Request for 'X-Forwarded-For' header and if exists takes the first 'X-Forwarded-For' IP address as sets as 
# Persist identifier.
# If the 'X-Forwarded-For' header does not exist then the client IP address is set as Persist identifier.
 
when HTTP_REQUEST { 
    if {[HTTP::header X-Forwarded-For] != ""} then {
persist uie [lindex [ split [lindex [HTTP::header values X-Forwarded-For] 0] "," ] 0]
    } else {
persist uie [IP::client_addr]
}
}

Cheers,

Kees
