Many HTTP requests cause the retrieval of slightly modified
instances of resources for which the client already has a
cache entry. Research has shown that such modifying
updates are frequent, and that the modifications are
typically much smaller than the actual entity. In such
cases, HTTP would make more efficient use of network
bandwidth if it could transfer a minimal description of the
changes, rather than the entire new instance of the
resource. This is called 'delta encoding.' This
document describes how delta encoding can be supported as a
compatible extension to HTTP/1.1.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
