CURLMOPT_PIPELINING_SITE_BL(3)                        Library Functions Manual

NAME
       CURLMOPT_PIPELINING_SITE_BL - pipelining host block list

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
       This functionality affects http only

EXAMPLE
       static char *site_block_list[] =
       {
         "www.haxx.se",
         "www.example.com:1234",
         NULL
       };

       int main(void)
       {
         CURLM *m = curl_multi_init();
         curl_multi_setopt(m, CURLMOPT_PIPELINING_SITE_BL, site_block_list);
       }

AVAILABILITY
       Added in curl 7.30.0
