Optimizing If statement conditions

You are absolutely right hoolio. I did the test again, this time setting the strings to lowercase in both conditions. It seems the consolidated statement is still faster, and the difference is a bit wider in this case. I won't post the whole thing anymore, just the avg-cycles:

timing on
when HTTP_REQUEST {
  if { [string tolower [HTTP::host][HTTP::uri]] equals "www.myhost.com/admin" } {
    HTTP::uri "/new_uri"
  }
}
avg-cycles 14762
avg-cycles 14892
avg-cycles 14804

timing on
when HTTP_REQUEST {
  if { [string tolower [HTTP::host]] equals "www.myhost.com" and [string tolower [HTTP::uri]] equals "/admin" } {
    HTTP::uri "/new_uri"
  }
}
avg-cycles 16219
avg-cycles 16526
avg-cycles 16626
