how to insert cookie and persist to it

Hi,dear irule

I have a pool cjj which has 10 members ,ration is the load blance method

I need to insert cookie and persist with cookie ,

for example client1 ----->VS---->pool member1 ,then insert one cookie(session cookie) to it, then persist this connection to the same pool member.

when HTTP::request {

if [HTTP::uri] starts_with "help"

pool cjj

persist cookie insert BIGIP_ABURL 0

}

when I want to apply it to the VS,it told me I need to add a persist profile

but I don't want to add a profile.because there are 10 pools under this vs and in this irule(don't want to use persist none in them,too many pools)

it will affect them

1:how to resolve this?

2:in the rule above,I don't set the cookie value,bigip will set it atuomatically?

pls help

Hi Jucao,

Sorry I don't have a lab work up for this. However, looking at the logic try the following


when HTTP_REQUEST timing on {
   set uri [string tolower [HTTP::uri]]
   if {[class match $uri starts_with gen3abURLs_SRWD29] } {
       if {([HTTP::cookie value_cookie] ne "")  } {
           scan [HTTP::cookie value_cookie] %s%d member port
            pool cjjlb member $member $port
    } else {
        pool cjjb
    }
}

when LB_SELECTED {
  set lbvalue "[LB::server_addr] [LB::server port]"
 }

when HTTP_RESPONSE {
  if {$lbvalue ne "" } {
     HTTP::cookie insert name value_cookie value $lbvalue path "/"
      }
}

I hope this helps
