[STANDARDS- TRACK] 2110 Palme Mar 97 MIME E-mail Encapsulation of Aggregate Documents, such as HTML (MHTML) This document describes a set of guidelines that will allow conforming mail user agents to be able to send, deliver and display these objects, such as HTML objects, that can contain links represented by URIs. [STANDARDS-TRACK] 2109 Kristol Feb 97 HTTP State Management Mechanism This document specifies a way to create a stateful session with HTTP requests and responses. It describes two new headers, Cookie and Set- Cookie, which carry state information between participating origin servers and user agents. The method described here differs from Netscape's Cookie proposal, but it can interoperate with HTTP/1.0 user agents that use Netscape's method.

HMAC can be used with any iterative cryptographic hash function, e.g., MD5, SHA-1, in combination with a secret shared key. The cryptographic strength of HMAC depends on the properties of the underlying hash function. This memo provides information for the Internet community.

While a mobility solution is not part of the Nimrod architecture, Nimrod does require that the solution have certain characteristics. We identify the requirements that Nimrod has of any solution for mobility support. We also classify and compare existing approaches for supporting mobility within an internetwork and discuss their advantages and disadvantages. This memo provides information for the Internet community. This memo does not specify an Internet standard of any kind. Ramos Informational [Page 21] RFC 2199 Summary of 2100-2199 January 1998 2102 Ramanathan Feb 97 Multicast Support for Nimrod : Challenges and Solution Approaches Nimrod does not specify a particular solution for multicasting. Rather, Nimrod may use any of a number of emerging multicast techniques. We identify the requirements that Nimrod has of a solution for multicast support.
