 ## Network panel overview
 
 The Network panel automatically records all network activity while DevTools is open. The first time you open the panel it may be empty. Reload the page to start recording, or simply wait for network activity to occur in your application.

-[cURL](http://curl.haxx.se/) is a command line tool for making HTTP transactions. The Network panel's **Copy as cURL** command recreates an HTTP request (including HTTP headers, SSL certificates, and query string parameters) and copies it as a cURL command string to the clipboard. You can then paste the string into a terminal window (on a system with cURL) to execute the same request.
