@ parameters. Some robots will spend hours juggling around query parameters
  @ or even forging fake query parameters in an effort to discover new
  @ behavior or to find an SQL injection opportunity or similar.  This can
  @ waste hours of CPU time and gigabytes of bandwidth on the server.  A
  @ suggested value for this setting is:

  @ <br> The following comma-separated GLOB pattern allows for exceptions
  @ in the maximum number of query parameters before a request is considered
  @ complex.  If this GLOB pattern exists and is non-empty and if it
  @ matches against the pagename followed by "/" and the number of query
  @ parameters, then the request is allowed through.  For example, the
  @ suggested pattern of "timeline/[012]" allows the /timeline page to
  @ pass with up to 2 query parameters besides "name".
