=head1 USAGE
|
|||
|
|
|
|||
|
|
Needs access to http://localhost:8080/gwc (or
|
|||
|
|
modify the address for another host).
|
|||
|
|
|
|||
|
|
If geowebcache is used inside GeoServer the url will be
|
|||
|
|
http://localhost:8080/geoserver/gwc
|
|||
|
|
|
|||
|
|
GeoWebCache 1.2 or higher.
|
|||
|
|
|
|||
|
|
Tip: To see if it's already set up correctly, just run this plugin
|
|||
|
|
with the parameter "autoconf". If you get a "yes", everything should
|
|||
|
|
work like a charm already.
