Annotation of embedaddon/curl/docs/cmdline-opts/header.d, revision 1.1.1.1

1.1       misho       1: Long: header
                      2: Short: H
                      3: Arg: <header/@file>
                      4: Help: Pass custom header(s) to server
                      5: Protocols: HTTP
                      6: ---
                      7: Extra header to include in the request when sending HTTP to a server. You may
                      8: specify any number of extra headers. Note that if you should add a custom
                      9: header that has the same name as one of the internal ones curl would use, your
                     10: externally set header will be used instead of the internal one. This allows
                     11: you to make even trickier stuff than curl would normally do. You should not
                     12: replace internally set headers without knowing perfectly well what you're
                     13: doing. Remove an internal header by giving a replacement without content on
                     14: the right side of the colon, as in: -H \&"Host:". If you send the custom
                     15: header with no-value then its header must be terminated with a semicolon, such
                     16: as \-H \&"X-Custom-Header;" to send "X-Custom-Header:".
                     17: 
                     18: curl will make sure that each header you add/replace is sent with the proper
                     19: end-of-line marker, you should thus \fBnot\fP add that as a part of the header
                     20: content: do not add newlines or carriage returns, they will only mess things up
                     21: for you.
                     22: 
                     23: Starting in 7.55.0, this option can take an argument in @filename style, which
                     24: then adds a header for each line in the input file. Using @- will make curl
                     25: read the header file from stdin.
                     26: 
                     27: See also the --user-agent and --referer options.
                     28: 
                     29: Starting in 7.37.0, you need --proxy-header to send custom headers intended
                     30: for a proxy.
                     31: 
                     32: Example:
                     33: 
                     34:  curl -H "X-First-Name: Joe" http://example.com/
                     35: 
                     36: \fBWARNING\fP: headers set with this option will be set in all requests - even
                     37: after redirects are followed, like when told with --location. This can lead to
                     38: the header being sent to other hosts than the original host, so sensitive
                     39: headers should be used with caution combined with following redirects.
                     40: 
                     41: This option can be used multiple times to add/replace/remove multiple headers.
