Applying lowercase iRule to HTTPS virtual server?

here is another Irule to do this

when HTTP_REQUEST {
# pool_group1 is the pool name for this virtual server
set Vuri [ string tolower [HTTP::uri]]
set Vheader [string tolower [HTTP::host]]
set Poolmember1 [active_members pool_group1] 
set Default_site www.mysitename.com

switch $Vheader {

    www.mysitename.com {
                        if { [HTTP::uri] ne $Vuri  } {
                        [HTTP::uri] $Vuri
                        }
                        else { pool pool_group1 }
                    }
    default { HTTP::redirect "https://$Default_site$Vuri"}
}
}
