A portable proxy to manage single-session WebDrivers (e.g. geckodriver),
allowing for simultaneous connections.
Before using a client or acquiring a client from a pool, ensure the session exists. Unless explicitly
specified, browsers are shut down after 12 hours of inactivity. For greater flexibility, please see
Dockerfile-SessionDriver-Firefox and Dockerfile. Dockerfile
exposes executables for x86_64-unknown-linux-gnu and x86_64-unknown-linux-musl.
Please see an example of how to use SessionDriver with Rust at ./src/lib.rs. As you might
notice, an additional, non-spec conforming route (/session/driver/{uuid}/status) is exposed to check the
status of a managed session.
