http to https cookie persistence

I have modified the iRule for our application timeout.

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

when HTTP_REQUEST {

This logs information about the TCP connections on *both* sides of the full proxy

set client_remote "[IP::client_addr]:[TCP::client_port]"

set client_local "[IP::local_addr clientside]:[TCP::local_port clientside]"

Log details for the request

log local0. "| REQ | $client_remote | $client_local | server_local | server_remote | [HTTP::cookie value ISASESSIONID] | [HTTP::uri]"

if { [HTTP::cookie exists "ISASESSIONID"] } {

persist uie [HTTP::cookie value "ISASESSIONID"]

}

}

when HTTP_RESPONSE {

set server_remote "[IP::server_addr]:[TCP::server_port]"

set server_local "[IP::local_addr serverside]:[TCP::local_port serverside]"

if { ![HTTP::cookie exists "ISASESSIONID"] } {

if { [HTTP::cookie "JSESSIONID"] ne "" } {

set newCookie [HTTP::cookie value JSESSIONID]

HTTP::cookie insert name "ISASESSIONID" value $newCookie path /

persist add uie [HTTP::cookie value "ISASESSIONID"]

}

}

log local0. "| RES | $client_remote | $client_local | $server_local | $server_remote | [HTTP::cookie value ISASESSIONID]"

}

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

I use the original weblogin irule from devcentral for jsessionid but it dint work when maintaining persistence from http to https switch.

Actually I am new to iRule. If you can help me to optimise the above irule except the log entry will be great.
