Nicholas, to save or supplement your and others’ off-site research, here’s a quick explanation of proxy servers and how they can be used for dynamic linking.
In today’s everybody’s watching and malicious folks are stalking you world, we’re most likely to know about proxy servers as a layer of indirection or prophylaxis to provide anonymous or infection-safe access to the Internet.
The basic idea of a proxy server is that it is a server running a program that takes your request from you for something (usually a page to view) on another server, and runs it through the proxy server’s program before handing the processed page off to you to complete your original request. In the case of a kid-safe firewall, a proxy server might ensure that only kid-friendly sites can be accessed or that certain ‘bad’ words get filtered out of the pages returned to the user.
When the proxy server runs a link annotation program we have a non-invasive way to add hypertext links and pop-up comments to documents viewed on the web. By non-invasive we mean that you don’t need write-access to change the source document (at some URL). By passing the document through a back-linking proxy server, the link server’s database maintains a mapping between the source document and the collection of annotation links that folks contribute into the link database. So before sending you the page you requested, the proxy’s back-link program processes the page and inserts the link annotations.
By way of example, to read a hypothetical (non-existent) page directly, you might go to this URL:
If O.net had a CRITLink back-link proxy server running on this sub-domain:
then you could read the link-annotated version of this hypothetical page by going to this URL:
The most convenient way that this was done in the CRIT.org days was for the source page author to include a ‘CRIT this page’ image/link inviting folks to redirect through the proxy server to see and contribute to the link annotations.
This additional description may help to explain our original suggestion that a link annotation proxy server is a convenient way to make real and dynamic Nicholas’ metaphor about our minds being active link containers.
