Title : Happy Eyeballs Considerations for HTTP State Management Mechanisms
Author : Eric Vyncke
Filename : draft-vyncke-v6ops-happy-eyeballs-cookie-00.txt
Pages : 5

Abstract:
HTTP servers usually save session states in their persistent storage
indexed by session cookies generated by the HTTP servers. It is up
to the HTTP user-agent to send this session cookie on each HTTP
request. Some HTTP servers check whether the cookie is associated
with the HTTP user-agent by the means of the user-agent IP address...
If the Happy Eyeball mechanism is used to select between IPv6 and
IPv4, it may happen that while using the same HTTP server, some HTTP
requests are done over IPv6 and the others over IPv4, which leads to
two different sets of session states in the HTTP server. This has
the consequence of inconsistencies at the HTTP server.
The only purpose of this document is to document this issue.
A similar problem arises with the use of non RFC 6888 compliant Large
Scale NAT (LSN) devices used to access an IPv4-only HTTP server.
