NAME
       CURLMOPT_PIPELINING_SERVER_BL - pipelining server blacklist

SYNOPSIS
       #include <curl/curl.h>

       CURLMcode     curl_multi_setopt(CURLM     *handle,    CURLMOPT_PIPELIN-
       ING_SERVER_BL, char **servers);

DESCRIPTION
       Pass a servers array of char *, ending with a NULL  entry.  This  is  a
       list  of  server  types  prefixes (in the Server: HTTP header) that are
       blacklisted from pipelining, i.e server types that  are  known  to  not
       support HTTP pipelining. The array is copied by libcurl.

       Note  that the comparison matches if the Server: header begins with the
       string in the blacklist, i.e "Server: Ninja 1.2.3" and  "Server:  Ninja
       1.4.0" can both be blacklisted by having "Ninja" in the backlist.

       Pass a NULL pointer to clear the blacklist.

DEFAULT
       The default value is NULL, which means that there is no blacklist.
