Hi,

The format for string match should be:

% string match

wrong args: should be "string match ?-nocase? pattern string"

And you shouldn't escape periods in a string comparison. They do not have a special meaning of "any character" like they do in regex.

The downside to a string match is that you can't use a wildcard for number of times a character class is repeated. A * will match any character zero to any number of times.

So you can check if the hostname matches x.y.example.com using:

string match -nocase {[a-z0-9]*.[a-z0-9]*.example.com} [HTTP::host]

But scan (Click here) will give you the ability to match a character class any number of times and the ability to save matches. Here are a few examples:

scan returns a count of the number of matches assuming you provide variables to save the matches in

% scan test1.test2.example.com {%[a-z0-9].%[a-z0-9].%[a-z0-9].%[a-z0-9]} a b domain tld

4

% puts "$a $b $domain $tld"

test1 test2 example com

Or:

% scan test1.test2.example.com {%[a-z0-9].%[a-z0-9].example.com} a b

2

% puts "$a $b"

test1 test2

So, you could try something like this:

 
 when HTTP_REQUEST { 
  
     Check if host header matches pattern, a.b.example.com 
    if {[scan [string tolower [HTTP::host]] {%[a-z0-9].%[a-z0-9].example.com} a b] == 2}{ 
  
       log local0. "[IP::client_addr]:[TCP::client_port]: Matched host [HTTP::host] with $a $b" 
       HTTP::redirect "https://application.store.com/app/jsp/initialGMCLanding.jsp?id=[HTTP::host]" 
  
    } elseif {[string match -nocase {[a-z0-9]*.example.com} [HTTP::host]]}{ 
  
        Redirect to default location 
       HTTP::redirect "https://application.store.com/app/jsp/initialGMCLanding.jsp" 
  
    } else { 
        Take some default action? 
    } 
 }
