Trailing / in URI

Not sure if concat is valid, but you could just redirect them after the initial logic and add the trailing slash like this:

when HTTP_REQUEST {
 Get URI and convert to lowercase
set uri [string tolower [HTTP::uri]]
 Log the lowercase URI
log local0. "lowercase uri: $uri"
 Find out if there is a period in the URL stopping when it sees a ?
if { [findstr $uri "." 0 "?"] eq "." }{
 do nothing -- not ending in a virutal directory, URI syntax is good.
log local0. "URI is not a directory"
}
elseif { not ($uri ends_with "/") }{
 HTTP::redirect http://[HTTP::host][HTTP::uri]/ 
 }
}

(might need to double-check my brackets there)

That way if they bookmark the page it should end up with the slash in it.
