User-Agent parse

Every time your web browser makes a request to a website, it sends a HTTP Header called the "User Agent". The User Agent string contains information about your web browser name, operating system, device type and lots of other useful bits of information.

But every browser sends its user agent in a different format, so decoding them can be very tricky.

The operation will show you what the user agent means; whether it's a popular system like Safari on iPad, Chrome on Windows, whether it's a search engine spider bot or security analysis tool.^[1]
