## Multi-target builds
`cache-dependency-path` input used to generate unuque cache key and it is not limited to only
dependencies files. The common case is to add a file containing the extr info about the specific
build, for example build target.
### Multi-target builds
The 'cache-dependency-path' input doesn't limit itself to dependency lock files only. It can also be used with additional files that contain details about the build settings. By using this method, caches for builds created for various operating systems, architectures, etc. can be separated.

### Caching with actions/cache
The caching capabilities of setup-go are limited to the simplest and most popular use cases. If fine-grained tuning of caching is required, it's recommended to disable the built-in caching and use [actions/cache](https://github.com/actions/cache).
```yaml
- uses: actions/setup-go@v4
with:
go-version: '1.17'
cache-dependency-path: go.sum cache-version.txt
- run: go run hello.go
```
## Caching with actions/cache
The caching capabilities of the action are limited for the simplest builds and can be ineffective in the real world
use cases. If the build requires fine-grained turning the built-in caching should be disabled and
[actions/cache](https://github.com/actions/cache) should be used.
Here the sample `actions/cache` configuration with the extending options allowing
- configuring paths to cache
- have different caches for rare changes dependencies and more often changed intermediate build files
- use `restore-key` input to restore the previous cache even if the current key cache has changed
- have different caches intermediate build files of different architectures
- have custom cache key for parallel builds
The example workflow below utilizes the `actions/cache` action and adds flexibility, for instance, it:
- allows to configure cache path
- allows to have different caches for rare changed dependencies and more often changed intermediate build files
- uses the `restore-key` input to restore the previous cache even if the current key cache has changed
- has different caches for the compiler's build outputs for different architectures
- has custom cache keys for parallel builds

## Restore-only caches
### Restore-only caches
If there are several builds on the same repo it might make sense to create a cache in one build and use it in the
others. The action [actions/cache/restore](https://github.com/marketplace/actions/cache-restore)
should be used in this case.
## Generate different caches
### Generate different caches
This advanced use case assumes manual definition of cache key and requires the use of
[actions/cache](https://github.com/actions/cache/blob/main/examples.md#go---modules)
## Parallel builds
### Parallel builds
To avoid race conditions during the parallel builds they should either
[generate their own caches](#generate-different-caches), or create the cache
for only one build and [restore](#restore-only-caches) that cache in the other builds.
