Cache about tileserver-php

[klokan]

I don't see the speed of metadata delivery as an issue at this point. Tiles should be for high performance served by webserver directly. Metadata attributes should not be computed but generated, if the tiles are generated in advance as well.

This has very low priority for me personally.

Implementation will bring installation issues (required rights to write from PHP).

Efficient caching should be done on the webserver (mod_cache) level or on CDN cache such as http://www.cloudflare.com/ or http://www.fastly.com/.

The target of this project should be only proper caching HTTP headers on the content which is dynamically generated.

This will bring more problems then benefits. Maybe this ticket shoud be opened in future. Now it's not issue of tileserver.
