HTTP/1.1 Implementor's Forum

This forum should help interested Web application designers and software implementors to gain hands-on experience with the HTTP/1.1 specification. The purpose of the service would be to open up discussions about implementation problems, solutions, traps and work-arounds specifically targeted for HTTP/1.1.

It is time to get extensive experience on how HTTP/1.1 compliant software and applications perform on the Internet at large. W3C would like to promote the deployment of HTTP/1.1 by providing this HTTP/1.1 Implementor's forum.

HTTP/1.0 Problems

A list of HTTP/1.0 applications that choke or in any way behave in a funny manner when talking to an HTTP/1.1 application.

HTTP/1.1 Test Sites

Origin Servers

Link Contact Notes

Common Lisp HTTP/1.1 Server John Mallery

Bell Labs Web Server: Bell Labs Test Server
(old) AT&T Bell Labs Server

Dave Kristol

Jigsaw Yves Lafon Source is available. Direct snapshot of the source tree is available from the CVS repository.

Apache Alexei Kosut Snapshots of the current development version (direct from our CVS repository) are available, if anyone wishes to download a copy.

WN: tests

John Franks See test page for a variety of examples including Digest authentication. There is a page for testing conditional requests depending on last modified date or ETag. A CGI script allows you to update the last-modified-date and change the ETag of this page.

Web Traffic Express: test cases

Mack Phelps for origin server issues. For the origin, use the URL /testcases/ to access the server; / will be redirected to www.software.ibm.com.

Agranat Systems EmWeb Server: 1.1 Test Server
1.1 Test Server With No Clock
Digest Authentication Test Server

Scott Lawrence The clockless server does not send Date headers, but does provide enough information for caches to operate correctly.

The Digest Authentication server has some tests for RFC-2069.

Proxy Servers

Address Contact Notes

Jigsaw: www26.w3.org:8001

Yves Lafon Proxy disabled for now, ask if you need to do some testing

Web Traffic Express: test2.software.ibm.com

Richard Gray for proxy server issues. Uses 1.1 on the origin server side, 1.0 on the user agent side.

Please do not use the proxy to access sites that contain material that could be considered offensive.

Clients

Home Contact Notes

Microsoft Internet Explorer 4 Uses 1.1 for direct requests, 1.0 through proxies

IaLib Chris Richardson A C++ framework for building Web clients

RPT-HTTPClient Ronald Tschalaer Written in Java

The Libwww Mini Robot Henrik Frystyk Nielsen A 1.1 web crawling client created using libwww.

1.0 Proxies

Because testing through 1.0 proxies with 1.1 user agents and servers, we are also listing some public proxy servers; our special thanks for thier making them available.

Address Contact Notes

Squid: squid.nlanr.net:3128

Duane Wessels This server forwards the status line from the response directly, rather than regenerating it as a 1.0 response.

Other Testing Opportunities and Resources

HTTP/1.1 test suite for intermediaries

The Measurement Factory has a comprehensive list of HTTP/1.1 tests related to intermediaries in their product CoAdvisor.

Weekly IETF Interoperability Tests

NOTE, as the HTTP WG is officially closed, this item is irrelevant The IETF HTTP Working Group is coordinating once a week events on which various implementations are made available by members of the group. For information, send mail to httptest@agranat.com.

Testing Content

The data used for recent W3C testing of HTTP performance, with links to the results of those investigations, is available for your testing.

Sample Software

W3C libwww and Jigsaw are free to try out - they both have HTTP/1.1 implementations.
