+	The THttpDataComposer class allows tokens to be added to a data buffer.
+	A token can be followed by a specified delimiter. The data buffer can be
+	released at any time, allowing a fresh set of data to composed. Resetting
+	the composer results in the data buffer being deleted.
+
+	An MHttpBufferSupplier object owns the data buffer into which the tokens
+	are placed. If there is not enough space for the tokens, the data composer
+	asks the buffer supplier to resize the buffer to at least the required size.
