Seeding a tile cache

A tile can be generated in two ways:

  • By the system administrator, usually in an automatic batch operation
  • By the user, who generates individual tiles by requesting ones not already cached

In both cases, the method of generation remains the same on the server side: a request is sent to the source WMS, which is returned and stored in the tile cache.

The first case, generating tiles by the system administrator in a batch operation, is known as “seeding”. This section will discuss considerations involved when seeding a cache in advance, as well as how to execute those requests.
