Synopsis
#include <curl/curl.h>
CURLMcode curl_multi_setopt(CURLM *handle, CURLMOPT_PIPELINING_SITE_BL,
                            char **hosts);Description
No function since pipelining was removed in 7.62.0.
Pass a hosts array of char *, ending with a NULL entry. This is a list of sites that are blocked from pipelining, i.e sites that are known to not support HTTP pipelining. The array is copied by libcurl.
Pass a NULL pointer to clear the block list.
Default
NULL, which means that there is no block list.
Protocols

{
  "www.haxx.se",

  curl_multi_setopt(m, CURLMOPT_PIPELINING_SITE_BL, site_block_list);
