| # URL | |
| The URL syntax is protocol-dependent. You find a detailed description in | |
| RFC 3986. | |
| If you provide a URL without a leading **protocol://** scheme, curl guesses | |
| what protocol you want. It then defaults to HTTP but assumes others based on | |
| often-used hostname prefixes. For example, for hostnames starting with `ftp.` | |
| curl assumes you want FTP. | |
| You can specify any amount of URLs on the command line. They are fetched in a | |
| sequential manner in the specified order unless you use --parallel. You can | |
| specify command line options and URLs mixed and in any order on the command | |
| line. | |
| curl attempts to reuse connections when doing multiple transfers, so that | |
| getting many files from the same server do not use multiple connects and setup | |
| handshakes. This improves speed. Connection reuse can only be done for URLs | |
| specified for a single command line invocation and cannot be performed between | |
| separate curl runs. | |
| Provide an IPv6 zone id in the URL with an escaped percentage sign. Like in | |
| "http://[fe80::3%25eth0]/" | |
| Everything provided on the command line that is not a command line option or | |
| its argument, curl assumes is a URL and treats it as such. | |
