Syntax errors on match_glob?

I've got a remarkably boring rule that I'm getting a syntax error on, and I don't understand why. I've also tried string_match and am getting similar errors, but I'm just not seeing what I'm doing wrong:

 

 

On https calls, detect no www and redirect to www

 

when HTTP_REQUEST {

 

if { [HTTP::host] matches_glob "blah*.com" } {

 

HTTP::redirect "https://www.[HTTP::host][HTTP::uri]"

 

}

 

}

 

 

 

 

I get this:

 

 

 

01070151:3: Rule [BLAH_HTTPS_NO_WWW] error:

 

line 3: [parse error: PARSE syntax 91 {syntax error in expression " [HTTP::host] matches_glob "blah*.com" ": extra tokens at end of expression}] [{ [HTTP::host] matches_glob "blah*.com" }]

 

 

 

 

Basically I'm just trying to redirect a number of numbered domains (say blah1.com - blah10.com) to www.blah1.com without writing rules for each one.

 

 

 

Any thoughts?
