+Help: Pass custom header(s) to proxy
+Protocols: HTTP
+Added: 7.37.0
+Category: proxy

+Example: --proxy-header "User-Agent: surprise" -x http://proxy $URL
+Example: --proxy-header "Host:" -x http://proxy $URL

+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 will make 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 will only mess things
+up for you.
+
+Headers specified with this option will not be included in requests that curl
+knows will not be sent to a proxy.
+
+Starting in 7.55.0, this option can take an argument in @filename style, which
+then adds a header for each line in the input file. Using @- will make curl
+read the header file from stdin.
+
+This option can be used multiple times to add/replace/remove multiple headers.
