IRule and Error Checking

It seems that the ends_with operator isn't returning a boolean value (or at least that's what is being inserted into the logs)

can't use non-numeric string as operand of "!"

while executing "if { ! [HTTP::uri] ends_with "/" }..."

maybe unRuleY can chime in as to why. Since it's not returning a boolean so you can't use the not operator with it.

But, you aren't out of luck, you can always use the built-in TCL string commands (Click here) to manipulate strings

Give this a try...

when HTTP_REQUEST { 
  if { [HTTP::uri] starts_with "/channel/" } {
    pool QA1
  } elseif {[HTTP::uri] starts_with "/performance/" } {
    pool QA2
  } elseif { [HTTP::uri] starts_with "/lead/" } {
    pool QA3
  } elseif { [string index [HTTP::uri] end] ne "/" } { 
    HTTP::redirect "https://[HTTP::host][HTTP::uri]/"
  } else {
    discard
  }
}

Now, you didn't state this, but your rule will only do the redirect if the above "starts_with" comparisions don't pass. If you want this to occur even on those uri's then you might want to move the ends_with piece to the beginning of the loop. Also, keep in mind, that some webservers won't like appending slashes to file name requests (ie. /dir/somefile.htm).
