I am dealing with some large datasets and would like to minimise the amount of data sent over the network. I am using OpenLayers' BBox strategy to only transfer the data that is needed but I am wondering whether I can simplify the output so that I can show lower zoom levels without having to transfer data with unnecessary accuracy/detail.
I am using GeoServer as a WFS server as part of the OpenGeo bundle.
Answer
WFS/GeoServer does not really provide any way to do generalization on the fly based on scale, but there is a special extension that does what you are looking for by doing some pregeneralization.
