Go on, put us to the test. Try our User-Agent and other HTTP header parser below and we’ll show you what information we can get.

Your HTTP headers have been automatically added below. Alternatively, you can paste your own HTTP headers with the format headername: headervalue, with one header per row, into the box to test. Once you're happy, press the submit button to see what you get.
