How to append to a match_class

I have this code:   if { ([class match $req_uri starts_with PROD_uri_to_redirecttossl]) } { HTTP::redirect "https://[HTTP::host][HTTP::uri]" }   but want something like this:   if ...

Okay, this may seem a little odd, but I've gotten to work as follows:

Data group:

/about/
/help/

iRule:

when HTTP_REQUEST { 
    if { [string first "/" [HTTP::uri] 1] eq -1 } {
         URI doesn't have a second "/" so just return URI
        set mod_uri [HTTP::uri]
    } else {
         return the first level URI minus trailing "/"
        set mod_uri [string range [HTTP::uri] 0 [string first "/" [HTTP::uri] 1]]
    }
    if { ( [class match "${mod_uri}/" equals my-dg] ) or ( [class match $mod_uri starts_with my-dg] ) } {
         do something here
        log local0. "match"
    }
}

Essentially, I take the requested URI (ex. "/about/me"), strip it down to its first level path minus the trailing slash ("/about"), then compare it two times against the data group:

  • Does the data group entry "/about/" equal the modified URI + trailing slash?
  • Does the data group entry "/about/" start with the modified URI?

It will match "/about", "/about/", and "/about/me", but not "/aboutme".
