<p>A process is disclosed for using the existing Universal Resource Identifier (URl) history feature (122) of browsers (121) to maintain user preference settings, or other state information, used by one or more web sites (101, 102, 103) or other systems. In one embodiment, when a user makes a particular preference selection on a web site (101, 102, 103), the user's selection is recorded on the user's computing device (120) in the browser's URI history (122) by causing the browser (121) to access a URI (130, 135, 136), or a set of URIs, representing the particular selection. The same or a different web site (101, 102, 103) may subsequently test the browser's URl history (122) for this particular URI or set of URIs by including approppate JavaScript (125) or other executable code in a page (124) requested by the browser (121). 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.</p> |
