Throttle incoming requests per minute
Hi Guys! Trying to write an iRule that throttles incoming requests but I can't get this very simple example to work. Basically my problem seems to be that the global connections variable never is being reset. Also, I'm not sure if I have to use a global variable in this case. The limit should only affect one particular VIP and the iRule is only used at this VIP. Throttle number of requests per minute when RULE_INIT { array set connections { } after 60000 -periodic { array set ::connections { } } } when HTTP_REQUEST { if { [info exists ::connections([IP::client_addr])] } { if { [incr ::connections([IP::client_addr])] > 10 } { HTTP::respond 200 content "You have passed the request threshold of 10/minute." set blocked 1 } } else { set ::connections([IP::client_addr]) 1 HTTP::respond 200 content "OK" } } Thankful for any advice! Kind regards, Patrik
