+== Serving Mapguide Tiles directly via Apache ==
+
+For scalability, it can be useful to get apache to serve your map tiles directly.
+
+This allows the map tiles to be cached and it frees up the mapguide server process, which during high load 
+may have a request queue.
+
+The implementation involves exposing a single map's tile cache directory via apache httpd.conf
+
+{{{
+<Directory "C:/Program Files/MapGuideOpenSource2.0/Server/Repositories/TileCache/Samples_Sheboygan_MapsTiled_Sheboygan/">
+    Options Indexes
+    ErrorDocument 404 /mapguide/seedSheboyganTile.php
+    Header set Cache-Control "max-age=86400, public"
+    AllowOverride None
+    Order allow,deny
+    Allow from all
+</Directory>
+Alias /sheboyganTiles/ "C:/Program Files/MapGuideOpenSource2.0/Server/Repositories/TileCache/Samples_Sheboygan_MapsTiled_Sheboygan/"
+}}}
+
+Restart Apache
+
+The attached file contains seedSheboyganTile.php which is used to generate tiles which haven't been seeded yet, [[BR]]
+save it in "C:\Program Files\MapGuideOpenSource2.0\WebServerExtensions\www"
+
+There is also a modified version of openlayers Mapguide.js which has a new option called "useHttpTile" which [[BR]]
+when set to true will generate requests for the tiles as they are stored internally by the TileService, [[BR]]
+the layer url then becomes http://localhost:8008/sheboyganTiles/
+
+The httpCacheDemo.html file assumes you have openlayers installed under "C:\Program Files\MapGuideOpenSource2.0\WebServerExtensions\www\openlayers" [[BR]]
+
+Simply add the updated Mapguide.js to the openlayers\lib\OpenLayers\Layer directory and then open the httpCacheDemo.html file to try it out.
