Proxy setup
How to set up Premip proxies in Selenium
Selenium should use the same Premip endpoint as curl. Configure the proxy on the WebDriver, then load one URL before a full crawl.
HTTP proxy on the driver
For Chrome, pass --proxy-server=http://HOST:PORT. If the browser prompts for auth, use an extension or a client that supports proxy user flags for your driver version.
Prefer proving curl first
If curl fails, Selenium will fail too. Fix credentials at the curl layer.
Sessions
One WebDriver instance should keep a sticky Premip session for a single browse path. Start a new driver after you rotate the IP.
Instructions
1. Verify with curl
Use the canary command from the cURL guide.
2. Launch one driver
Open a single page through the proxy and read the public IP in the page or via a check URL.
3. Keep one job per session
Do not rotate in the dashboard while the driver is mid-navigation.
chrome --proxy-server="http://HOST:PORT"

The fastest way to prove credentials work before you configure a larger client.
Sticky sessions vs rotation
Keep one IP for a journey. Rotate between independent jobs without changing credentials.
