Creating and Modifying Access Keys

When you author maps, you can embed a hidden access key within each map
layer or Zoom Goto definition. Then, each time a user attempts to access that
map layer or Zoom Goto definition, the access key is automatically sent to
the server along with the request for the data. Autodesk MapGuide Server
then verifies that the access key is on the list of access keys assigned to that
resource before providing the data.
For example, you could specify in Autodesk MapGuide Server Admin that the
text string FL1WMTD is an access key for the SDF file lakes.sdf. An author
creating a map could then embed that string in a map layer that uses data
from lakes.sdf. Then, whenever a user zooms in or out on the map or works
with a feature on that layer, the Viewer sends the access key along with the
request for data. This happens automatically without the user ever being
aware of the access key or needing to enter any information. Autodesk
MapGuide Server verifies that the access key is on the list of access keys
assigned to the resource lakes.sdf in Autodesk MapGuide Server Admin, and
then provides the data. Thus, the map author needs to coordinate with the
Autodesk MapGuide Server administrator to make sure that the access key
the author enters in a map layer is properly assigned to the specific resource
that provides data to that map layer.
Access keys are also useful for creating maps that are valid for only a specific
period of time, as you can change the values of access keys and their start and
end dates. Access keys also make it easy to stop serving data from a specific
resource quickly. For step-by-step instructions on creating access keys, choose

Help Contents, click the Index tab, and look up "access keys, creating."
