.TH CURLOPT_SUPPRESS_CONNECT_HEADERS 3 "13 February 2017" "libcurl 7.54.0" "curl_easy_setopt options"
|
||
|
|
.SH NAME
|
||
|
|
CURLOPT_SUPPRESS_CONNECT_HEADERS \- Suppress proxy CONNECT response headers from user callbacks
|
||
|
|
.SH SYNOPSIS
|
||
|
|
.nf
|
||
|
|
#include <curl/curl.h>
|
||
|
|
|
||
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SUPPRESS_CONNECT_HEADERS, long onoff);
|
||
|
|
.fi
|
||
|
|
.SH DESCRIPTION
|
||
|
|
When \fICURLOPT_HTTPPROXYTUNNEL(3)\fP is used and a CONNECT request is made,
|
||
|
|
suppress proxy CONNECT response headers from the user callback functions
|
||
|
|
\fICURLOPT_HEADERFUNCTION(3)\fP and \fICURLOPT_WRITEFUNCTION(3)\fP.
|
||
|
|
|
||
|
|
Proxy CONNECT response headers can complicate header processing since it's
|
||
|
|
essentially a separate set of headers. You can enable this option to suppress
|
||
|
|
those headers.
|
||
|
|
|
||
|
|
For example let's assume an HTTPS URL is to be retrieved via CONNECT. On
|
||
|
|
success there would normally be two sets of headers, and each header line sent
|
||
|
|
to the header function and/or the write function. The data given to the
|
||
|
|
callbacks would look like this:
|
||
|
|
|
||
|
|
.nf
|
||
|
|
HTTP/1.1 200 Connection established
|
||
|
|
{headers}...
|
||
|
|
|
||
|
|
HTTP/1.1 200 OK
|
||
|
|
Content-Type: application/json
|
||
|
|
{headers}...
|
||
|
|
|
||
|
|
{body}...
|
||
|
|
.fi
|
||
|
|
|
||
|
|
However by enabling this option the CONNECT response headers are suppressed, so
|
||
|
|
the data given to the callbacks would look like this:
|
||
|
|
|
||
|
|
.nf
|
||
|
|
HTTP/1.1 200 OK
|
||
|
|

|
