public interface HttpContext
HttpContext represents execution state of an HTTP process. It is a structure
that can be used to map an attribute name to an attribute value. Internally
HTTP context implementations are usually backed by a HashMap
.
The primary purpose of the HTTP context is to facilitate information sharing among various logically related components. HTTP context can be used to store a processing state for one message or several consecutive messages. Multiple logically related messages can participate in a logical session if the same context is reused between consecutive messages.
