Syntax:

a_number

[Default: -1]

It specifies the maximum allowed number of concurrent server-push connections per session.

A negative number (default) means no limitation at all. Zero means no server push is allowed at all.

Notices that

  • A desktop has at most one server-push connection.
  • A desktop might be killed accidentally. For example, a user closes a browser window. In this case, the server might not be able to detect it. When specifying this, it is better to specify the maximum allowed number of desktops.
