EXPLANATION

This tab is used to define how displayed resources shall be cached. If you select Disable from the pull-down menu, the resources are not cached at all and all the required resources are acquired directly from the network. Acquired resources are not saved in cache; all resources maintained in memory are lost when the application is terminated.

If you select Enable from the pull-down menu, all new resources are first acquired from the network in the same way as for Disable. In this mode, however, the acquired resources are always stored in the cache. The Enable setting takes effect the next time the browser is launched.

If you select Enable, the cache is referenced first when resources are requested. If the resources have already been stored in the cache, they are acquired from it rather than downloaded via the net. The content is only kept in the cache for a certain period of time, after which it expires and must be acquired by accessing the network if required at a later point. Resources not found in cache are also acquired from the network. Acquired resources are written to cache.

There are two basic types of resources, "mapping paths" and other "resources." Mapping paths are resources that link other resources together through coordinate transformations. Other resources include raster data, vector data, as well as resources of maps themselves, such as the coordinate systems in which they are placed. It is possible to specify a cache for each type of resource.
