iRule to Limit Connections from Source IP to Destination IP

Hi Aaron,

 

 

It's Apache on a Linux Based Web Server.

 

 

This is another blast I had at the iRule:-

 

 

when RULE_INIT {

 

set static::max_connections_pi 2

 

set ::Inpicall =0

 

set static::active_connections_pi 0

 

}

 

when HTTP_REQUEST {

 

if { [HTTP::uri] contains "URI" } {

 

set inpicall=1;

 

incr ::active_connections_pi 1

 

if { not [HTTP::cookie exists "inpicheckout"] and $::active_connections_pi > $::max_connections_pi} {

 

HTTP::respond 302 Location "Website.html" "Connection" "Close" "Cache-Control" "no-cache" "Pragma" "no-cache" TCP::close

 

}

 

}

 

}

 

when HTTP_RESPONSE {

 

if $Inpicall==1

 

{ incr ::active_connections_pi -1

 

$Inpicall=0

 

}

 

}

 

when CLIENT_CLOSED { if $inpicall==1 { incr ::active_connections_pi -1 $Inpicall=0

 

}

 

}

 

 

Would this only max connections for traffic hitting the URI or all Connections hitting the Virtual Server?
