For ajax request, adding Math.Random() or timestamp is world wide known method :)

However, the two events it shows you how to hook into are the completion of the loading of the map, and OnSelectionChaged. I need to hook into RequestMap(), which is a function, not an event of any kind, as far as my limited understanding tells me. Unless someone can give me a technique to achieve that, I'll go back to hacking the original function, and am aware of the problem of losing that customization when upgrading MapGuide. One other issue I have is caching of my xmlhttp request. I can work around this by adding a random parameter to the query, but realize this is a hack. I am now experimenting with adding cache control headers on the server side. Does anyone know of the best way to achieve this (fully cross-browser compatible)?
