+The purpose of this component is to provide an asynchronous alternative to the
synchronous {{{ HttpMethodExecutor }}} in http-common.
+
+depends on
+
+ * Java 1.4
+ * commons-logging (really needed? if feasible I'd rather do without this
dependency)
+ * http-common
+
+The rationale behind trying to avoid dependency on a logging framework is to
keep the component reusable by projects that have already standardized on a
certain logging framework.
+
+provides
+
+ * asynchronous execution interface for HTTP requests. The {{{ HttpConnection
}}} for communication is passed as an argument when the interface is used.
Responses and errors are reported as callbacks.
+
+ a. {{{ HttpAsyncLink }}} interface for sending requests asynchronously
+ a. {{{ HttpAsyncCallback }}} interface
+
+ * default implementation of the asynchronous execution interface. The default
is to spawn a new background thread that sends the request over the connection
and waits for a response. The callback interface is used by that thread.
+
+ a. {{{ StdAsyncLink }}} class implementing {{{ HttpAsyncLink }}}
+
+ * result lookup interface for HTTP responses.
+
+ a. {{{ HttpAsyncResult }}} interface for checking whether the response is
available, and getting it
+ a. {{{ HttpAsyncNotify }}} interface extending {{{ HttpAsyncResult }}} with
a wait/notify mechanism
+
+ * default implementation of a callback handler and result provider. The
default implementation uses the same error retry handling as {{{
DefaultHttpRequestRetryHandler }}}.
