|

<p>The maximum concurrent streams setting only controls the maximum number

of streams that can be initiated by the remote peer. In other words,
|

when this setting is set to 100, this does not limit the number of
|
||
concurrent streams that can be created by the caller.</p>
|
||
<p>It is recommended that this value be no smaller than 100, so as to not
|
||
unnecessarily limit parallelism. However, any value is legal, including
|
||
0. If <code>max</code> is set to 0, then the remote will not be permitted to
|
||
initiate streams.</p>
|
||
<p>Note that streams in the reserved state, i.e., push promises that have
|
||
been reserved but the stream has not started, do not count against this
|
||
setting.</p>
|
||
<p>Also note that if the remote <em>does</em> exceed the value set here, it is not
|
||
a protocol level error. Instead, the <code>h2</code> library will immediately reset
|
||
the stream.</p>
