The technical details (frequently asked questions about the proxy servers)
For those interested in what goes on behind the scenes with respect to the central proxy servers, here are a few details.
Q. Which software does the proxy service use?
A. Squid - see www.squid-cache.org for details.
Q. Is there a preference for using an automatically or manually configured proxy with a Web browser?
A. The preference would be for an automatic configuration. However, some Web-based applications (e.g. the Quicktime player) will work only with a manually set proxy. When manually setting the proxy, use the name proxy.abdn.ac.uk.
Q. How does the automatic proxy configuration work?
Q. Why do I see some browsers configured with http://www.abdn.ac.uk/local/autoproxy.pac and others with http://www.abdn.ac.uk/local/autoproxy.php?
A. This is for historical reasons. In our earliest documentation, the first URL (autoproxy.pac) was used. This used the standard extension (.pac) for autoproxy configuration URLs. As the demands on the proxy service
Q. I use several methods of connecting to the Internet (eg. a dial-up connection, a broadband connection at home and a direct connection when on-campus), do I need to set a proxy for each?
A. If you are using Internet Explorer, then the answer is yes, you do need to configure each connection individually. The same applies if you use more than one dial-up providers. Generally, each connection will
appear in Internet Explorer's Options | Internet Options | Connections menu as a separate entry (the exception to this is when your broadband connection is via a router rather than a USB modem, such a connection is
treated as a LAN connection by Internet Explorer). If you are using another browser such as Mozilla Firefox, then one setting applies to all connections.
