This information can be used by, for example, Postfix +/* SMTP clients or other Postfix delivery agents. +/* +/* The connection cache is organized into logical destination +/* names, physical endpoint names, and connections. +/* +/* As a specific example, logical SMTP destinations specify +/* (transport, domain, port), and physical SMTP endpoints +/* specify (transport, IP address, port). An SMTP connection +/* may be saved after a successful mail transaction. +/* +/* In the general case, one logical destination may refer to +/* zero or more physical endpoints, one physical endpoint may +/* be referenced by zero or more logical destinations, and +/* one endpoint may refer to zero or more connections. +/* +/* The exact syntax of a logical destination or endpoint name +/* is application dependent; the \fBscache\fR(8) server does +/* not care. A connection is stored as a file descriptor together +/* with application-dependent information that is needed to +/* re-activate a connection object. Again, the \fBscache\fR(8) +/* server is completely unaware of the details of that +/* information. +/* +/* All information is stored with a finite time to live (ttl). +/* The connection cache daemon terminates when no client is +/* connected for \fBmax_idle\fR time units. +/* +/* This server implements the following requests: +/* .IP "\fBsave_endp\fI ttl endpoint endpoint_properties file_descriptor\fR" +/* Save the specified file descriptor and connection property data +/* under the specified endpoint name.
