can't read "need_cookie": no such variable

Is it because the need_cookie contains the special characters?i do not think so.

 

 

Any advice on this?may you post the whole irule?

when RULE_INIT {

 

; set ::total_active_clients 0

 

; set ::max_active_clients 3000

 

set ::holding_page_be "http://www.testing.com"

 

set ::debug_mode 0

 

log local0. "rule session_limit initialized: total/max/debug_mode: $::total_active_clients/$::max_active_clients/$::debug_mode"

 

}

 

 

when HTTP_REQUEST {

 

; test cookie presence

 

if {[HTTP::uri] contains "maxLimit.do"} {

 

if {[HTTP::cookie value "SeatOfferPage"] == "successful"} {

 

log local0. "TE kick out user after step 1!"

 

}

 

}

 

if {[HTTP::cookie exists "TM2003218"]} {

 

set need_cookie 0

 

set client_id [HTTP::cookie "TM2003218"]

 

; if cookie not present & connection limit not reached, set up client_id

 

;log local0. "old client id $client_id, current number $::total_active_clients"

 

if {$::debug_mode >= 4} {log local0. "Returning customer with cookie value: $client_id"}

 

} else {

 

if {$::total_active_clients < $::max_active_clients} {

 

if {[HTTP::uri] contains "SeatAvailability.do"} {

 

set need_cookie 1

 

set client_id [format "%08d" [expr { int(100000000 * rand()) }]]

 

if {$::debug_mode >= 1} {log local0. "1-New customer with cookie value: $client_id, IP:[IP::client_addr], total_active_clients: $::total_active_clients"}

 

incr ::total_active_clients

 

; otherwise redirect

 

;log local0. "new client id $client_id, current number $::total_active_clients"

 

}

 

} else {

 

; set need_cookie 2

 

if {$::debug_mode >= 2} {log local0. "Excced limit now, total_active_clients: $::total_active_clients"}

 

HTTP::respond 302 Location $::holding_page_te "Cache-Control" "no-cache" "Pragma" "no-cache"

 

return

 

}

 

}

 

}

 

when HTTP_RESPONSE {

 

 

; insert cookie if needed

 

if {$need_cookie == 1} {

 

HTTP::cookie insert name "magicClientName" value "TM2003218"

 

HTTP::cookie insert name "TM2003218" value $client_id

 

}

 

 

; if {$need_cookie == 2} {

 

; HTTP::respond 302 Location $::holding_page_te "Cache-Control" "no-cache" "Pragma" "no-cache"

 

; return

 

; }

 

 

}

 

when CLIENT_CLOSED {

 

; decrement current connection counter for this client_id

 

if {$::total_active_clients > 0} {

 

incr ::total_active_clients -1

 

if {$::debug_mode >= 1} {log local0. "Client dropped, total_active_clients: $::total_active_clients"}

 

}

 

}

Upz..

It looks like you are only setting the need_cookie variable under certain conditions. So on any requests where those conditions are not met the variable $need_cookie is not set.

 

You need to ALWAYS set the need_cookie variable to some value (like at the top of the irule where you are setting the other variables) since you are calling for it unconditionally under the HTTP_RESPONSE event. Hope that makes sense.

if I insert set ::need_cookie below the set ::debug_mode 0 does it helps? Will it considered as setting it as global variable?

shouldn't need_cookie be local variable rather than global one?

 

 

instead of setting it in RULE_INIT, i think it should be initialized in HTTP_REQUEST.
