CLOSEIMMED (JANUS DEFINE parameter)

<section begin="desc" /><section end="desc" />

CLOSEIMMED is a parameter on JANUS DEFINE, which defines and sets characteristics of a Janus port. See the List of JANUS DEFINE parameters.

This parameter indicates that if a lost connection is noticed by the Janus PST, the PST should BUMP the Model 204 thread associated with the connection immediately. If CLOSEIMMED is not specified a lost connection will only cause request termination when the web thread invokes a $Web function. Typically, the Janus PST will not notice that a connection has been lost until the user issues a $Web_Done because until then there will be no TCP/IP calls that can discover that the connection has been lost. Without the CLOSEREAD parameter (:hdref refid=clread.) the CLOSEIMMED parameter will probably have no effect.

CLOSEREAD and CLOSEIMMED are useful for ensuring that CPU and I/O intensive web requests will be terminated immediately should the user become impatient and cancel the request.

Valid only for WEBSERV ports.
