+Long: proxy-header
+Arg: <header>
+Help: Pass custom header LINE to proxy
+Protocols: HTTP
+Added: 7.37.0
+---
+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 \fBnot\fP 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.
+
+This option can be used multiple times to add/replace/remove multiple headers.
