iRule proxy

For bot detection, here is a sample in CodeShare that shows how to detect a bot via the "User-Agent" http header.

As for url patterns, the easiest way is to use a switch statement with file globbing (star based wildcards)

 

 

when HTTP_REQUEST {
  switch -glob [HTTP::uri] {
    "*foo.html" {
       do something
    }
    "/path/*" {
       do something else
    }
    "/dir1/*" -
    "/dir2/*" -
    "/dir3/*" {
       do something if either of the above 3 match.
    }
  }
}

 

 

The basics here is that the URI is available with the HTTP::uri command in the HTTP_REQUEST event. You can assign that to a variable and do if/else statements, a switch statement (shown above), a match to a class list (as shown in the ControllingBots sample code).

 

 

Hope this helps...
