A process is disclosed for using the existing Universal Resource Identifier (URI) history feature of browsers to maintain user preference settings, or other state information, used by one or more web sites or other systems. In one embodiment, when a user makes a particular preference selection on a web site, the user's selection is recorded in the browser's URI history by causing the browser to access a URI (or a set of URIs) representing the particular selection. The same or a different web site may subsequently test the browser's URI history for this particular URI by including appropriate JavaScript or other executable code in a page requested by the browser. Depending upon the outcome of this test, the web site and/or the page's executable code may take an appropriate action or inaction consistent with the preference selection.
