--proxy-header

Extra header to include in the request when sending HTTP to a proxy. You may specify any number of extra headers. This is the equivalent option to --header but is for proxy communication only like in CONNECT requests when you want a separate header sent to the proxy to what is sent to the actual remote host.

curl makes sure that each header you add/replace is sent with the proper end-of-line marker, you should thus not add that as a part of the header content: do not add newlines or carriage returns, they only mess things up for you.

Headers specified with this option are not included in requests that curl knows are not be sent to a proxy.

This option can take an argument in @filename style, which then adds a header for each line in the input file (added in 7.55.0). Using @- makes curl read the headers from stdin.

This option can be used multiple times to add/replace/remove multiple headers.
