CURLMOPT_PIPELINING |
Pass 1 to enable or 0 to disable. Enabling pipelining on a multi
handle will make it attempt to perform HTTP Pipelining as far as
possible for transfers using this handle. 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.
As of cURL 7.43.0, the value is a bitmask, and you can also pass 2 to try to multiplex the new
transfer over an existing HTTP/2 connection if possible.
Passing 3 instructs cURL to ask for pipelining and multiplexing
independently of each other.
As of cURL 7.62.0, setting the pipelining bit has no effect.
Instead of integer literals, you can also use the CURLPIPE_*
constants if available.

CURLMOPT_MAXCONNECTS |
Pass a number that will be used as the maximum amount of
simultaneously open connections that libcurl may cache.
By default the size will be enlarged to fit four times the number
of handles added via curl_multi_add_handle.
When the cache is full, curl closes the oldest one in the cache
to prevent the number of open connections from increasing.
|
CURLMOPT_CHUNK_LENGTH_PENALTY_SIZE |
Pass a number that specifies the chunk length threshold for pipelining
in bytes.
|
CURLMOPT_CONTENT_LENGTH_PENALTY_SIZE |
Pass a number that specifies the size threshold for pipelining
penalty in bytes.
|
CURLMOPT_MAX_CONCURRENT_STREAMS |
The set number will be used as the maximum number of concurrent streams for a connections that cURL
should support on connections done using HTTP/2. Valid values range from
1 to 2147483647 (2^31 - 1).
The value passed here would be honored based on other system resources properties.
Default is 100.
|
CURLMOPT_MAX_HOST_CONNECTIONS |
Pass a number that specifies the maximum number of connections to a
single host.
|
CURLMOPT_MAX_PIPELINE_LENGTH |
Pass a number that specifies the maximum number of requests in a
pipeline.
|
CURLMOPT_MAX_TOTAL_CONNECTIONS |
Pass a number that specifies the maximum number of simultaneously
open connections.
|
CURLMOPT_PUSHFUNCTION |
Pass a callable that will be registered to handle server
pushes and should have the following signature:
int pushfunction(resource $parent_ch, resource $pushed_ch, array $headers)
-
parent_ch
-
The parent cURL handle (the request the client made).
-
pushed_ch
-
A new cURL handle for the pushed request.
-
headers
-
The push promise headers.
The push function is supposed to return either
CURL_PUSH_OK if it can handle the push, or
CURL_PUSH_DENY to reject it.
