That's a great example and thanks for sharing it with the community.
This aFleX will just work perfectly, now we can do a couple of changes to optimize it (limit the AX CPU usage from that aFleX).
. "array" is more efficient than "list" when you try to look for an entry in a list
. creation of variables takes some CPU resources + memory (not a lot a all but still) => avoid unnecessary variables
The new aFleX with those changes looks like that:
Code:
when RULE_INIT { array set :: CACHEURLS [list "youtube.com" "vxa1_vxa2" "googlevideo.com" "vxa1_vxa2" "google.com" "vxa3_vxa4" "google.de" "vxa3_vxa4" "facebook.com" "vxa1_vxa2" "apple.com" "vxa3_vxa4" "fbcdn.net" "vxa1_vxa2" "clipfish.de" "vxa3_vxa4" "googlesyndication.com" "vxa 1_vxa2" "337.com" "vxa-service-group" "aol.com" "vxa-service-group" "bigfishgames.com" "vxa-service-group" "bigpoint.net" "vxa-service-group" "bild.de" "vxa-service-group" "chip.de" "vxa-service-group" "doubleclick.net" "vxa-service- group" "computerbild.de" "vxa-service-group" "dailymotion.com" "vxa-service-group" "dreamies.de" "vxa-service-group" "ea.com" "vxa-service-group" "ebay.de" "vxa-service-group" "friendscout24.de" "vxa-service-group" "gmx.net" "vxa-service- group" "immobilienscout24.de" "vxa-service-group" "jappy.de" "vxa-service-group" "jappy.tv" "vxa-service-group" "kicker.de" "vxa-service-group" "last.fm" "vxa-service-group" "live.com" "vxa-service-group" "microsoft.com" "vxa-service- group" "msn.com" "vxa-service-group" "myvideo.de" "vxa-service-group" "mzstatic.com" "vxa-service-group" "n-tv.de" "vxa-service-group" "pop6.com" "vxa-service-group" "rtl.de" "vxa-service-group" "soundcloud.com" "vxa-service-group" "spiegel.de" "vxa- service-group" "streamfarm.net" "vxa-service-group" "twitter.com" "vxa-service-group" "ytimg.com" "vxa-service-group" "mdn.net" "vxa-service-group" "whatismyipaddress.com" "vxa-service-group" "whatismyip.com" "vxa-service-group" "wer-kennt- wen.de" "vxa-service-group" "wooga.com" "vxa-service-group" "yahoo.com" "vxa-service-group" "zynga.com" "vxa-service-group"] } when HTTP_REQUEST { set HOST [string tolower [HTTP::host]] set URI [string tolower [HTTP::uri]] set HOST_LIST [split $HOST "."] set HOST [lindex $HOST_LIST [expr [llength $HOST_LIST]-2]].[lindex $HOST_LIST [expr [llength $HOST_LIST]-1]] if { [info exists ::CACHEURLS($HOST)] } { #log "ServiceGroup $::CACHEURLS($HOST)" pool $::CACHEURLS($HOST) } else { #log "not whitelisted; pool Gateway" pool Gateway } }2. Should this apply to VIP or the Wildcard?
