What HTTP Headers is my browser sending?

Every time your web browser opens a web page, it sends a "request" for that page. Part of that request includes a series of "headers".

Here is the list of all the headers your browser sent when requesting this page.

There were 5 headers sent:

ACCEPT */* ACCEPT-ENCODING gzip, deflate CONNECTION keep-alive HOST www.whatismybrowser.com USER-AGENT newspaper/0.2.8

We sorted your browser's HTTP headers alphabetically If you want, you can see your HTTP headers in the order your browser sent them.

These headers may vary from site to site (in particular the HOST and COOKIE headers!) depending on your settings.

If you're curious and want to learn more about HTTP (a protocol which the World Wide Web relies on) and HTTP Headers, please read the Wikipedia pages on Hypertext Transfer Protocol and List of HTTP header fields.

Curious about Client Hints? We detect them too!

Client Hints are the new approach to identifying web browsers, built to eventually replace user agents. We're following the development and switch to using them closely. We've also built a tool to detect client hints that your web browser is sending.
