Hi Tim, I think your suggestion makes sense. One thing we could probably do is on startup check each layer for its SRS and only include those in the default capabilities document. If the user wants to change it after that they are free to do so.
It would take a bit of book keeping to manage when new layers are added but I think it could work. Andrea, what do you think? -Justin Tim Schaub wrote: > Hey- > > A small exercise with my results next to each step. > > 1) Click: > http://sigma.openplans.org/geoserver/ows?SERVICE=WMS&REQUEST=GetCapabilities > (wait 3 seconds) > 2) Save the result to your desktop, call it ows.xml. > 3) Drag ows.xml into Firefox (wait 10 seconds). > > Granted, the delay in step one is largely my fault for living in the > boonies.
