Common Problems

A session encapsulates a user's entire state: cookies, local storage, indexedDB, cache files, and browser configurations. Reusing sessions reduces server overhead and decreases bot detection rates.

Best Practices

  1. User Data Directory: Launch Chrome pointing to a dedicated folder containing the browser profile data.
  2. Graceful Shutdowns: Ensure Chrome writes session states to disk before terminating the process.
  3. Session Lock Bypass: Clear stale .lock files from the Chrome profile directory before launching a daemon.
