.SH NAME
|
|
CURLOPT_PROXYHEADER \- set of 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);
|
|
.fi
|
|
.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\(aqs.
|
|
|
|
The headers set with this option is only ever used in requests sent to a proxy
|
|
- when there is 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 causes your request to send an invalid header.
|
|
|
|
Using this option multiple times makes the last set list override the previous
|
|
ones. Set it to NULL to disable its use again.
|
|
|
|
libcurl does not copy the list, it needs to be kept around until after the
|
|
transfer has completed.
