### cache
`cache` is used to specify a list of files and directories which should be
cached between builds. Caches are stored according to the branch/ref and the
job name. They are not currently shared between different job names or between
branches/refs, which means that caching will benefit you if you push subsequent
commits to an existing feature branch.
cached between builds.
**By default the caching is enabled per-job and per-branch.**
If `cache` is defined outside the scope of the jobs, it means it is set
globally and all jobs will use its definition.

#### cache:key
_**Note:** Introduced in GitLab Runner v1.0.0._
The `key` directive allows you to define the affinity of caching
between jobs, allowing to have a single cache for all jobs,
cache per-job, cache per-branch or any other way you deem proper.
This allows you to fine tune caching, allowing you to cache data between different jobs or even different branches.
The `cache:key` variable can use any of the [predefined variables](../variables/README.md):
Example configurations:
To enable per-job caching:
```yaml
cache:
key: "$CI_BUILD_NAME"
untracked: true
```
To enable per-branch caching:
```yaml
cache:
key: "$CI_BUILD_REF_NAME"
untracked: true
```
To enable per-job and per-branch caching:
```yaml
cache:
key: "$CI_BUILD_NAME/$CI_BUILD_REF_NAME"
untracked: true
```
To enable per-branch and per-stage caching:
```yaml
cache:
key: "$CI_BUILD_STAGE/$CI_BUILD_REF_NAME"
untracked: true
```
If you use **Windows Batch** to run your shell scripts you need to replace the `$` with `%`:
```yaml
cache:
key: "%CI_BUILD_STAGE%/%CI_BUILD_REF_NAME%"
untracked: true
```
## Jobs
`.gitlab-ci.yml` allows you to specify an unlimited number of jobs. Each job
