CLOSEIMMED (JANUS DEFINE parameter)

Bump lost web threads immediately.

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

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 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.
