I should be able to open and edit shapefiles outside of ArcIMS that are currently used in MapServices. This feature isn't working.
The SHAPEWORKSPACE "shared" attribute default is incorrect in the ArcXML
documentation. The default is "false."
Solution or Workaround
In order to permit shapefile editing outside of ArcIMS, set "shared" to "true."
NOTE: If the shapefiles are on a separate computer from the ArcIMS Spatial Server, the amount of time required to process a request increases noticeably.
