This implementation report is for http-v11-spec-rev-05 &
http-authentication-03 to progress to Draft Standard.

This report is abbreviated; see
    http://www.w3.org/Protocols/HTTP/Forum/Reports/
for more explanation and individual implementation reports. Many
thanks to the contributors who took the time to report on their
systems, and to Jim Gettys for accumulating the results and
encouraging sufficient testing and reporting.

We have surveyed implementations for whether each feature in these
specifications have been tested against independent interoperable
implementations. In the survey, nearly all features have had more than
two clients, servers, and proxies tested. Since the survey was
performed, almost all of the _remaining_ features have been tested,
and we feel confident in bringing forward the specifications as Draft
Standard at this point.

We have implementation & testing reports from 20 implementations:

* libwww-perl NG-alpha-0.11 from Aas Software: a Perl HTTP
  client library (Gisle Aas)
* HTTPClient V0.4-dev from Ronald Tschalaer: a client library in Java
* libwww 5.1k from the World Wide Web Consortium: a client library in C,
  with various tools built on top (Henrik Frystyk Nieslen)
* Internet Explorer 4 from Microsoft Corporation: a full-feature web
  browser (Yaron Goland)
* Netscape Navagator and Communicator 5 from Netscape Communication
  Corporation (Gagan Saksena): a full-feature web browser and editor
* Netscape Enterprise Server 3.51 from Netscape Communication
  Corporation: a HTTP/1.1 server (Mike Belshe)
* Apache 1.3b6 from the Apache Group: a HTTP/1.1 Server and incomplete
  caching proxy (Roy Fielding)
* DMKHTD 1.06f from Dave Kristol, Bell Labs: a HTTP/1.1 Server
* Microsoft IIS 4.0 from Microsoft Corporation: a HTTP/1.1 Server
  (Henry Sanders)
* WN 2.0.0 from John Franks, Northwestern University Math Department:
  a HTTP/1.1 Server
* SRE-http 1.3a from Daniel Hellerstein, USDA: a HTTP/1.1 Server  
* HASS 1.00d.a from Applied Theory Communications: a Application
  Server Suite (Patrick McManus)
* Microsoft Proxy Server 2.0 from Microsoft Corporation a HTTP/1.1
  Caching Proxy server (Lester Waters)
* CL-HTTP 67.47 from John Mallery, MIT AI Lab: a combined sever and
  caching proxy, including a client and Web Walker application
* Jigsaw 2.0beta from the World Wide Web Consortium, a combined server
  and caching proxy (Yves Lafon)
* Raptor Firewall 5.1 from Axent Technologies, a HTTP/1.1 firewall
  Proxy (no caching) (Robert Polansky)
* GiambyNetGrabber 0.65 from GiambiSoft: a client Internet mirroring
  tool (Giambattista Bloisi)
* Millicent Proxy 1.0 (3 separate implementations) from Digital
  Equipment Corporation: the MilliCent microcommerce system, including
  Server, Proxy and Gateway (reverse proxy) (Steve Glassman).  The
  separate implementations were by different people at different
  geographical locations in different programming languages.

Table of Results:

Each implementation was surved to review the http-spec-v11-rev
document and the http-authentication document to review each section
for whether all of the features in that section were implemented and
tested for interoperability of that feature against a separate
independent implementation. The codes below indicate different
responses:

't'   tested against another independent implementation
'y'   implemented but not tested against independent implementation
'n'   not implementated
'-'   not applicable to this type of implementation
