NimbostratusCookie persistence with URI over ride
The rule is intended to persist on a cookie called JSESSIONID except if the uri contains jsessionid, it then uses the findstr command to pass out the jsessionid i.e. J2EE806189900 it the maps the to c...
Based on this more complete information, I would have update the rule:
class WD_members {
"J2EE806189900 10.235.69.155:58000"
"J2EE806190000 10.235.69.154:58000"
"J2EE809133200 10.235.69.153:58000"
}
rule sap_version9 {
when CLIENT_ACCEPTED {
set add_persist 1
}
when HTTP_RESPONSE {
if { [HTTP::cookie exists "JSESSIONID"] and $add_persist } {
persist add uie $jsess
log local0. "HTTP response SAPCookie [HTTP::cookie JSESSIONID]"
set add_persist 0
}
}
when HTTP_REQUEST {
Note the cookie is JSESSIONID
log local0. "HTTP URL [HTTP::uri]"
log local0. "HTTP request SAPCookie [HTTP::cookie JSESSIONID]"
set jsess [findstr [HTTP::uri] "jsessionid" 12 ")"]
if { $jsess eq "" } {
log local0. "No jsessionid in URI, using cookie"
if { [HTTP::cookie exists "JSESSIONID"] } {
persist uie [HTTP::cookie "JSESSIONID"]
}
} else {
log local0. "Found jsessionid in URI: $jsess"
set node [findclass $jsess $::WD_members " "]
if { $node ne "" } {
log local0. "Sending request to $node"
pool wdsapphire_pool member $node
} else {
log local0. "Unknown J2EE key: $jsess"
}
}
}
}
