CURLMOPT_PIPELINING_SERVER_BL - pipelining server block list

#include <curl/curl.h>
CURLMcode curl_multi_setopt(CURLM *handle, CURLMOPT_PIPELINING_SERVER_BL,
                            char **servers);

No function since pipelining was removed in 7.62.0.

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 blocked 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 block list, i.e "Server: Ninja 1.2.3" and "Server: Ninja 1.4.0" can both be blocked by having "Ninja" in the list.

Pass a NULL pointer to clear the block list.

The default value is NULL, which means that there is no block list.

HTTP

static char *server_block_list[] =
{
  "Microsoft-IIS/6.0",
  "nginx/0.8.54",
  NULL
};
int main(void)
{
  CURLM *m = curl_multi_init();
  curl_multi_setopt(m, CURLMOPT_PIPELINING_SERVER_BL, server_block_list);
}

Added in 7.30.0

Returns CURLM_OK if the option is supported, and CURLM_UNKNOWN_OPTION if not.
