The ArcGIS Server Development Blog has a entry explaining map caching for beginners, with an emphasis on ESRI products applications. From the entry: "Map caching is a very effective way to make your ArcGIS Server maps run faster. When you create a map cache, the server draws the entire map at several different scales, then stores copies of the map images. The server can then distribute these images whenever someone asks for a map. It’s much quicker for ArcGIS Server to hand out a cached image than to draw the map each time someone requests it. Another benefit of caching is that the amount of detail in the image doesn’t noticeably affect how quickly the server can distribute the copy." See also related stories.

TileCache 1.4 Released 2 comments
[+]
The OpenLayers mailing list announced the release of TileCache 1.4. From the announcement: "TileCache provides a Python-based WMS/TMS server, with pluggable caching
mechanisms and rendering backends. In the simplest use case, TileCache
requires only write access to a disk, the ability to run Python CGI
scripts, and a WMS you want to be cached. With these resources, you can
create your own local disk-based cache of any WMS server, and use the
result in any WMS-C supporting client, like OpenLayers, or any TMS
supporting client, like OpenLayers and worldKit." See also the OSGeo Tile Map Service specification.

Cosmos Globalbase Browser
[+]
Ogle Earth reports on a new "browser" from Japan. Here is their summary "New geobrowser alert: The Cosmos Globalbase Browser, out of Japan. There are instructions in English, but language remains a bit of a barrier, and often I'm not quite sure what I'm supposed to be doing. Still, it's all brand new, there appears to be open-source origins, and the premise is an interesting one:"
It's still quite cryptic as to what it is so perhaps we can discuss in comments. From what I gathered when I quickly glanced over it was that it is a way to build a global cache of geospatial data, or a way to create a huge data repository with data from all around the web???
