This is the kind of stuff that Big Brother extension scripts are for.

Using your favourite scripting language (shell, perl, python, ...)
it should be fairly easy to script retrival of this dynamic URL.
Say, something along this (completely untested, I'll leave the
debugging to you):

  #!/bin/sh

  # Pick up the BB server defs
  BBHOME=/usr/local/bb
  export BBHOME
  . $BBHOME/etc/bbdef-server.sh

  COLOR=green   # Be an optimist until we decide otherwise
  
  # Generate the URL
  TIMESTAMP="date +%s"
  URL="http://www.kilroytravels.com/servlet/Satellite?pagename=get&cid=1076588865040&SC=DK&uxd=$TIMESTAMP";

  # Run the test using bbnet
  $BBHOME/bin/bbnet "$URL" >/tmp/urltest.out

  # Now see what result we got
  if test "$?" != 0
  then
     # Oops - something very wrong, flag an error
     COLOR=red
     MSG="Could not talk to server"
  else
    # Grab the HTTP status 
    read HTTPVER RC MESSAGE </tmp/urltest.out
    case $RC in
     '200'|'401'|'301'|'302')
        MSG="Web is OK"
        ;;
     *)
        MSG="Error on website"
        COLOR=red
        ;;
    esac
  fi

  # Tell the world about it
  $BB $BBDISP "status www,kilroytravels,com.http $COLOR `date`

  $MSG

  `cat /tmp/urltest.out`
  "

  exit 0

Put this script in $BBHOME/ext/, make sure it is executable, and
put the name of the file into the $BBHOME/etc/bb-bbexttab and
restart Big Brother.
