Task 1 of 4

What is a client?

A client is anything that initiates a request - browsers, mobile apps, scripts, even other servers. In this task, open the lab site and identify what your browser reveals about itself in its request.

Open the Website panel, inspect the request context and look for the browser identity signal.

Need a hint?

Look for the User-Agent request header.
