DataGroup with > operator for connection limit

I am trying to limit the number of connections coming in, with 2 limits. One for projects that will be busy, and 1 for everything else.

The problem i've run into, is i'd like to be able to use Datagroups instead of the variables at the RULE_INIT but I can not seem to get the comparison to work when I switch it to use the integer data group.

This would allow us to adjust the maximums on the fly. With it in the RULE_INIT section, any time you adjust those numbers, it resets the activeConnections which means we lose track of all the connections we currently have.

when RULE_INIT {
This holds the number of currently active connections.
set ::activeConnections 0
This is the maximum number of connections allowed for high volume projects.
set ::maximumHighVolumeConnections 4
This is the maximum connections allowed for the entire datacenter.
set ::maximumConnections 6
}
if we have too many connections respond with an error page stating we're too busy.
if {$::activeConnections > $::maximumConnections}
{
log local0. "Maximum sessions exceeded active sessions is $::activeConnections max sessions is $::maximumConnections"
HTTP::respond 200 content "We are currently experiencing extermely high volume please try back later."
}
elseif { ($::activeConnections >  $::maximumHighVolumeConnections) and [matchclass [HTTP::path] starts_with $::HighVolumeProjects]}
{
if we have too many connections from high volume projects respond with an error page stating we're too busy.
log local0. "High Volume Client Not Allowed active sessions is $::activeConnections max sessions is  $::maximumHighVolumeConnections'"
HTTP::respond 200 content "We are currently experiencing high volume please try back later."
}
