Martin Duerst has submitted a draft of The Archived-At Message Header Field. Briefly this proposes adding a semi-permanent URL for each e-mail message posted to a mailing list to the e-mail header. This is an insanely good idea, that I wish everyone would start using immediately. The W3C mailing lists already use X-Archived-At for this purpose. I just wish more lists would follow suit.
The Apache Software Foundation has published The Common Gateway Interface (CGI) Version 1.1, an informational RFC that describes "'current practice' parameters of the 'CGI/1.1' interface developed and documented at the U.S. National Centre for Supercomputing Applications. This document also defines the use of the CGI/1.1 interface on UNIX(R) and other, similar systems."
