.TH CURLOPT_PROXYHEADER 3 "November 04, 2020" "libcurl 7.77.0" "curl_easy_setopt options"
.SH NAME
CURLOPT_PROXYHEADER \- custom HTTP headers to pass to proxy
.SH SYNOPSIS
.nf
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXYHEADER,
struct curl_slist *headers);
.SH DESCRIPTION
Pass a pointer to a linked list of HTTP headers to pass in your HTTP request
sent to a proxy. The rules for this list is identical to the
\fICURLOPT_HTTPHEADER(3)\fP option's.
The headers set with this option is only ever used in requests sent to a proxy
- when there's also a request sent to a host.
The first line in a request (containing the method, usually a GET or POST) is
NOT a header and cannot be replaced using this option. Only the lines
following the request-line are headers. Adding this method line in this list
of headers will only cause your request to send an invalid header.
Pass a NULL to this to reset back to no custom headers.
.SH DEFAULT
NULL
