This means that if you add a second request that can use an already existing connection, the second request will be \&"piped" on the same connection rather than being executed in parallel. When using pipelining, there are also several other related options that are interesting to tweak and adjust to alter how libcurl spreads out requests on different connections or not etc. .SH DEFAULT 0 (off) .SH PROTOCOLS HTTP(S) .SH EXAMPLE TODO .SH AVAILABILITY Added in 7.16.0 .SH RETURN VALUE Returns CURLM_OK if the option is supported, and CURLM_UNKNOWN_OPTION if not. .SH "SEE ALSO" .BR CURLMOPT_MAX_PIPELINE_LENGTH "(3), " .BR CURLMOPT_PIPELINING_SITE_BL "(3), " .BR CURLMOPT_CONTENT_LENGTH_PENALTY_SIZE "(3), " .BR CURLMOPT_CHUNK_LENGTH_PENALTY_SIZE "(3), " .BR CURLMOPT_MAX_HOST_CONNECTIONS "(3), " .BR CURLMOPT_MAXCONNECTS "(3), " .BR CURLMOPT_MAX_HOST_CONNECTIONS "(3), "
