NAME¶
CURLOPT_HTTP_VERSION - specify HTTP protocol version to use
SYNOPSIS¶
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HTTP_VERSION, long version);
DESCRIPTION¶
Pass
version a long, set to one of the values described below. They force
libcurl to use the specific HTTP versions. This is not sensible to do unless
you have a good reason. You have to set this option if you want to use
libcurl's HTTP/2 support.
- CURL_HTTP_VERSION_NONE
- We don't care about what version the library uses. libcurl will use
whatever it thinks fit.
- CURL_HTTP_VERSION_1_0
- Enforce HTTP 1.0 requests.
- CURL_HTTP_VERSION_1_1
- Enforce HTTP 1.1 requests.
- CURL_HTTP_VERSION_2_0
- Attempt HTTP 2.0 requests. libcurl will fall back to HTTP 1.x if HTTP 2.0
can't be negotiated with the server.
DEFAULT¶
CURL_HTTP_VERSION_NONE
