NimbostratusCookie Persistence
Hi,
I need to set cookie persistence for website with 8 nodes
Currently we are using Cookie Hash, but it seems to fail.
Here is our mechanism :
A customer connect to the website and he receive a PHPSESSID, he enter his login and password, then we need to persist him based on the value of its PHPSESSID. The PHPSESSID is unique for the eight nodes.
Sometimes, components like flash puts cookie in URI (ex : /flash.php?PHPSESSID=1f8210f5355c336c233ab08ee3ce1bc7)
Can I implement an iRule to persist my customers ?
We can't use source_addr because of aol and other bad isp, we can't use cookie insert because some heavy clients can't accept it.
Thanks
Gilles
- perhaps you can make reference to this one:
rule WeblogicJSessionPersist {
when CLIENT_ACCEPTED {
set add_persist 1
}
when HTTP_RESPONSE {
if { [HTTP::cookie exists "JSESSIONID"] and $add_persist } {
persist add uie [HTTP::cookie "JSESSIONID"]
set add_persist 0
}
}
when HTTP_REQUEST {
if { [HTTP::cookie exists "JSESSIONID"] } {
persist uie [HTTP::cookie "JSESSIONID"]
} else {
set jsess [findstr [HTTP::uri] "jsessionid" 11 ";"]
if { $jsess != "" } {
persist uie $jsess
}
}
}
by replacing JSESSIONID with PHPSESSID and change [findstr [HTTP::uri] "jsessionid" 11 ";"] to [findstr [HTTP::uri] "PHPSESSID" 10 ";"] 
Gilles_Marec_33Thanks, so I will try this
-------------------------------------------------------------
rule PHPPersist {
when CLIENT_ACCEPTED {
set add_persist 1
}
when HTTP_RESPONSE {
if { [HTTP::cookie exists "PHPSESSID"] and $add_persist } {
persist add uie [HTTP::cookie "PHPSESSID"]
set add_persist 0
}
}
when HTTP_REQUEST {
if { [HTTP::cookie exists "PHPSESSID"] } {
persist uie [HTTP::cookie "PHPSESSID"]
} else {
set phpsess [findstr [HTTP::uri] "PHPSESSID" 11 ";"]
if { $phpsess != "" } {
persist uie $phpsess
}
}
}
}
