WebDAV

Users can configure sccache to cache incremental build artifacts in a remote WebDAV service. The following services all expose a WebDAV interface and can be used as a backend:

• Ccache HTTP storage backend
• Bazel Remote Caching.
• Gradle Build Cache

Set SCCACHE_WEBDAV_ENDPOINT to an appropriate webdav service endpoint to enable remote caching. Set SCCACHE_WEBDAV_KEY_PREFIX to specify the key prefix of cache.

The SCCACHE_WEBDAV_RW_MODE environment variable can be set to READ_ONLY to make sccache use this backend in read-only mode. The default is READ_WRITE.

Credentials

Sccache is able to load credentials from the following sources:

• Set SCCACHE_WEBDAV_USERNAME/SCCACHE_WEBDAV_PASSWORD to specify the username/password pair for basic authentication.
• Set SCCACHE_WEBDAV_TOKEN to specify the token value for bearer token authentication.
