irule with forward command increase a lot number of connections

Question

Hi,
I have configured following irule the problem is that with forward command the number of conections goes from 100 to 5000.
Is this behavior normal? LTM ver11.4.1&nbsp;
when HTTP_REQUEST {
  if { [string tolower [HTTP::host]] equals "my.domain.com" } {
    forward
  } else { discard }
}
Best Regards,
MC&nbsp;

I don't think the forward command is behaving the way you may think it should.

Assuming this is a standard (non-forwarding) VIP, try this instead:
when HTTP_REQUEST { 
    if { not ( [string tolower [HTTP::host]] equals "my.domain.com" ) } { 
        discard 
    } 
}
