By looking at the User-Agent that the HTTP client may (or may not) send.
Here's what my Firefox sends

User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:102.0) Gecko/20100101 Firefox/102.0

Most HTTP clients can be configured to send whatever you please.

# The can even set apt's User-Agent ;-)
# Check /usr/share/doc/apt/examples/configure-index for details.

I have used the "User Agent Switcher and Manager" add-on for Firefox in
the past to convince a site that I was using some old version of IE just
so I could login. Switching back to Firefox after login was no problem
:-o

Fortunately, that site has since been updated.

Hope this helps,
