[mapguide-internals] 1.2 warnings?

[Walt Welton-Lair]

We have the method to clear the cache on the TileService API, but right
now it won't be automatically called after a user upgrades to 1.2.

I think we should indicate in the Notes that users should manually clear
their cache (delete all folders in their <TileCache> directory).

Out of curiosity though, what will happen if a user forgets to clear
their cache?  Is the new cache structure sufficiently different that new
tiles will automatically be generated?  If they modify the map
definition (or any dependent resources), will both new and any old tiles
be deleted?  Or will the old tiles remain behind?

Regarding the new cache directory structure...

When a map definition is modified, all cached tiles are cleared out from
a base folder, so a change to the map will automatically clear out any
tiles using the old path structure, since it shares the same root
folder.

If no resources are modified, it will require a method call to clear the
cache, or the manual deletion of the folder

I added the note about changes in the AJAX viewer.  Before adding the
part about the cache directory structure changes, I guess I should
confirm whether the old tiles will automatically be removed or whether
the user will need to clear the cache manually.

Were there other changes around the base classes and ASP.Net/Java, or
were those in 1.1?

Thanks for fixing up those pages!  We should add those differences to
the release notes page
(http://trac.osgeo.org/mapguide/wiki/Release/1.2/Notes).
