[mapguide-users] Adjusting subsequent views

[Kenneth Skovhede, GEOGRAF A/S]

I'm sure it can be done.
However, it seems fairly advanced.
I would suggest that you have a look at OpenLayers:
http://openlayers.org

With OpenLayers, you can have your MapGuide map as a base layer,
and then put an overlay with your custom layer.
You can then override the mapagent path in the overlay to point to your 
customization page, rather than mapagent.fcgi.

If you want to stick with the WebLayout based you will most likely get 
better results with a manually added overlay image.
The problem with the manual approach is passing on events to the image 
below.

Another option would be to have all calls to mapagent.fcgi point to your 
PHP script, and then make the script
act as a relay page for those calls that you are not interrested in.
