[mapguide-users] A question on MgTileService.GetTile() function

[Kori Maleski]

The AJAX viewer dynamically assigns an image ID to a URL that consists of a
GETTILEIMAGE request.

On a Windows XP machine when using Internet Explorer, this GETTILEIMAGE URL
and resulting .png/.jpg are stored in the Temporary Internet Files folder.

On a Windows XP machine when using Firefox, these are stored in a profile
folder - Local Settings\Application
Data\Mozilla\Firefox\Profiles\q6c40rzw.default\Cache.
Firefox encrypts the cache.  You can view the contents by typing
"about:cache" in the Firefox URL, and follow the links.

On a Windows XP machine when using Safari, the cache is stored in an SQLLite
database.


The Ajax viewer will perform GETTILEIMAGE for tiles within the map view.
Your browser settings for caching will determine whether the request is
performed or not if a tile that has been previously requested is within the
view.

The Ajax viewer will calculate which tile row/columns fall within the view
extent at the current zoom threshold, then perform the requests for those
row/column tiles.

The ID assigned to the image starts at 0 for the map session and increments
up, and has no bearing on the row/column order.

The URL contains all of the relevant row/column and scale info obviously.

Maciek, as Jackie sad, it does produce a cached tile - but on the server
side. I don't know how and if AJAX stores it's cached data locally.
