iRules, persistences, persistence profiles.

Hi

 

I've some doubts... I'll try to explain myself so apologizes for my English...

 

 

- Could anyone give me the differences between using: "session add uie $MyCookie 100" vs "persist uie $MyCookie 100", please ¿?

 

 

- I would like to use persistence with cookies from an iRule, should I manage this iRule as a persistence profile or just like a normal iRule...

 

 

- Is a good practice using a profile persistence "cookie in mode insert" and using iRules as a resource (with this situation I don't have to put Set-Cookie at the first HTTP_RESPONSE event).

 

 

 

FYI: (is an example in lab environment... I should reduce the memory impact etc..).

 

 

 

when HTTP_REQUEST {

 

set SwSetCookie 0

 

if { [HTTP::cookie "MyCookie"] != ""} {

 

set Cookie [HTTP::cookie "MyCookie"]

 

persist uie $Cookie 100

 

log local0.alert "Valor de la Cookie: $Cookie"

 

} else {

 

log local0.alert "No tengo Cookie activo el SW de Set-Cookie"

 

set SwSetCookie 1

 

}

 

pool MyPool

 

}

 

 

 

when HTTP_RESPONSE {

 

if { [HTTP::header Set-Cookie] starts_with "MyCookie" } {

 

set NuevaCookie [getfield [getfield [HTTP::header Set-Cookie] "=" 2] ";" 1]

 

log local0.alert "Add Persistencia Cookie: $NuevaCookie contra $MyServer"

 

persist add uie $NuevaCookie 100

 

}

 

}

 

 

 

when SERVER_CONNECTED {

 

if { $SwSetCookie == "1" } {

 

set MyServer [IP::server_addr]

 

log local0.alert "Primera conexion contra el servidor: [IP::server_addr]"

 

}

 

}
