services WMS, WMTS, TMS, VirtualEarth/Bing and Google Maps requests: Supported Tile Services
ability to respond to untiled WMS requests by merging tiles from the cache or forwarding them to the WMS source: Tile Assembling

KML superoverlay generation
data provided by WMS backends (GDAL supported sources planned)
cache types:
configurable metatiling
on-the-fly tile merging for combining multiple tiles into a single image
image post-processing (recompression and quantization) when arriving from a backend
interprets and produces cache control headers: Last-Modified, If-Modified-Since, Expires
multithreaded seeding utility that can seed specific zoom levels or specific areas (e.g. seed levels 0 to 12 of all tiles intersecting Colorado)
ability to add a custom watermark on stored tiles
produces a CGI/FastCGI executable for use with webservers other than Apache
configurable symbolic linking of blank tiles to save disk space
