I've been working with OpenLayers for a while, but problem got a question with WFS.

Not sure if it's supported by WFS, or OpenLayers, I want to achieve something like this, mostly for cache purpose:

As user pans/zooms the map, OpenLayers keeps sending out WFS requests with BBOX. I want to make coordinates in such requests keep only 3 decimal digits, in a sense, aligning to 0.001 degrees. Do I have to tinkle with OpenLayers, or is it built-in?


I'm thinking about tiling for WFS, like TMS and WMTS do. Just we don't render image here, instead we "render" XML files.


I don't know if there are efforts to tile WFS, but there are alternatives. Most vector tile implementations build upon GeoJSON chunks sent to the browser. A lot of information is linked on the OpenStreetMap wiki.

A new development I find pretty interesting is mapnik-vector-tile, built upon the incredible Mapnik map rendering engine. You find a handsome demo over at MapBox.
