Simple

SpatialCache is cache server written entirely in python. It has been designed to be flexible and powerful.

Flexible

Even it has been designed to work with a WMS as backend, it can be used beyond this scope without any trouble. You can use it as a general purpose cache if you want. Think of it as a small squid, that show it's true power when serving WMS requests.

Powerful

The multithreaded architecture makes it safe and scalable. GET request have been optimized to be incredibly fast. POST requests allows you to seed different zoom levels of a given request adding only a single param (Ex.: ZOOM=1,3,5-8). DELETE requests are used to clean folders using params filters hierarchy that you have defined.

3. Set the path to your WMS in configuration.xml
4. Start the server "python spatialcache.py -c configuration.xml"
