CURLMOPT_PIPELINING_SITE_BL - pipelining host block list

Added in curl 7.30.0

NULL, which means that there is no block list.

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.

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); }
