[OSM-talk] Local WMS server?

True.

False, sadly.

Even in the minuscle subset of WMS query that JOSM uses, it will
exactly specify the bounding box it wants, and the WMS server is
expected to deliver exactly that. So if you managed to configure a
proxy or something that would store the images, this would only work
if the image you have exactly fits the current map view in JOSM,
otherwise it means "file not found".

This is really something that needs to be solved in the JOSM WMS
plugin. It is not a lot of work really; the WMS plugin would just have
to be able to create a file and serialize all currently displayed
images into it. It just hasn't been done yet.

Bye
Frederik
