Ensure that you are familiar with the JEP 124 draft standard. More information is available at http://www.jabber.org/jeps/jep-0124.html.
See httpbind.conf File Location for information on finding this file.
Set the httpbind.requests parameter to the maximum number of concurrent requests a single client can send to the gateway.
The default is 2. For example:
The number of concurrent requests a client can make to the gateway. If the value of this parameter is less than the value for the JEP 124 hold attribute in the client request, the value for this parameter will be set to hold+1. Do not set this parameter to 1, as doing so could severely degrade performance. See To Set the JEP 124 hold Attribute for Client Requests to the XMPP/HTTP Gateway and Table B–1 for more information on the httpbind.hold parameter.
Save and close httpbind.conf.
Restart the gateway using the tools provided by the web or application server.
