> Note: The `id` defined in `actions/cache` must match the `id` in the `if` statement (i.e. `steps.[ID].outputs.cache-hit`)
## Known limitation
- `action/cache` is currently not supported on GitHub Enterprise Server. <https://github.com/github/roadmap/issues/273> is tracking this.
Since GitHub Enterprise Server uses self-hosted runners, dependencies are typically cached on the runner by whatever dependency management tool is being used (npm, maven, etc.). This eliminates the need for explicit caching in some scenarios.
