!ArcWeb/PublicHTML/arcwebtcp
This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

File contents
<html><head><title>ArcWeb and the Internet</title> </head><body><h1><img src="#!arcweb">ArcWeb & the Internet</h1> ArcWeb handles the fetching via a variety of different methods. Since ArcWeb uses only the socket level interface provided by Acorn TCP/IP, it will also run over anything else which provides an identical SWI interface (chunk &41200). ArcWeb supports<ul> <li>HTTP (HyperText Transfer Protocol) <li>FTP (File Transfer Protocol) <li>SMTP (Simple Mail Transfer Protocol <li>NNTP (Network News Transfer Protocol) <li>Finger <li>Telnet <li>Gopher <li>WAIS </ul>although WAIS is achieved through the use of proxy services such as those available at wwwcache.hensa.ac.uk. ArcWeb talks HTTP to proxy servers which perform the interaction with the remote site and send back the result via the HTTP protocol. Non-documents (eg. WAIS menus) are returned as HTML documents generated by the proxy server. Proxy servers are useful things to run on firewall machines as it allows people inside the firewall to access the Web services.<p> Other facilities supported by <strong>ArcWeb</strong> include<ul> <li>Transparent handling of <em>Location</em> indicating that a document has moved. The redirection is detected whilst the original response is being read and the query replaced by a request for the new URL. Note that if a failure occurs whilst fetching the replacement URL, any errors reported will be reported as having come from the original document requested and not the resultant of the search. There is no limit to the number of <em>Location</em> directives that may be chained together, ArcWeb will continue following the trail until the answer is found </ul> <h3>Testing your Configuration</h3> You can test the configuration of the nameservers by using the dialogue boxes accessed via the <img src="#!arcweb" alt="ArcWeb icon bar icon"> menu. You can look up hosts by name or by IP address. Enter the query in the writable icon and choose the lookup type in the radio icons, and then press RETURN or click on the Run Query button. The answers will be looked up and entered into the display icon below, with a menu to see all the answers. <hr> </body><address><a href="http://www.dsse.ecs.soton.ac.uk/">S.N.Brodie</a><br> Department of Electronics & Computer Science<br> University of Southampton</address></html>
