CURLMOPT_CONTENT_LENGTH_PENALTY_SIZE - size threshold for pipelining penalty

Added in curl 7.30.0

0, which means that the size penalization is inactive.

No function since pipelining was removed in 7.62.0. Pass a long with a size in bytes. If a transfer in a pipeline is currently processing a request with a Content-Length larger than this CURLMOPT_CONTENT_LENGTH_PENALTY_SIZE(3), that pipeline is not considered for additional requests, even if it is shorter than CURLMOPT_MAX_PIPELINE_LENGTH(3).

int main(void) { CURLM *m = curl_multi_init(); long maxlength = 10000; curl_multi_setopt(m, CURLMOPT_CONTENT_LENGTH_PENALTY_SIZE, maxlength); }
