Re: [geowebcache-users] Error Calling layers from Google maps

[Arne K. <ak...@op...>]

I don't know the answer, but if clearing the cache on the browser helps, 
then it seems highly unlikely that this is a GWC problem. The only 
explanation I can think of is if you configured the client before you 
configured GWC, and then the client cached the "not found" response. But 
GWC does not set headers that would encourage such caching anyway.
