Cache Settings

Settings for cache server. Some of the features are updated automatically when Map Module or Layers are modified. All fields are required unless explicitly stated.

  • Meta Buffer Size (optional)
    additional buffer (in px) to your tile size, use it to fix symbol artifacts on tile edges or label issues

    blank: General Settings settings will be used

  • Meta Tile Size (optional)
    meta tiles size used to create cache from source to reduce number of requests
