However, if a page +has been optimized or not for a given browser is often not easy to determine +unless explicitly stated. + +<p>When testing Dillo on a set of real websites, we need to be sure that those +pages are not optimized for Dillo, as otherwise it would skew our perception. + +<h2>Proposal</h2> + +<p>To address this issue, web authors are encouraged to tag their pages if they +were optimized for Dillo (or other web browsers). We propose the following meta +tag:</p> + +<pre><code> +<meta name="optimized-for" content="dillo"> +</code></pre> + +<p>Multiple entries must be specified in multiple tags: + +<pre><code> +<meta name="optimized-for" content="dillo"> +<meta name="optimized-for" content="elinks"> +<meta name="optimized-for" content="w3m"> +</code></pre> + +<p>The version of the web browser can be <em>optionally</em> specified after the +<code>/</code> separator, like it would appear in the <code>User-Agent</code> +HTTP header: + +<pre><code> +<meta name="optimized-for" content="dillo/3.2.0"> +<meta name="optimized-for" content="elinks/0.11"> +</code></pre> + +<p>Including the version is encouraged, as it will let developers know which +features were available when the optimization was performed. Multiple version +lines can also be provided for the same web browser. + +<h2>Parsing</h2> + +<p>When a web browser loads an HTML page which has an <code>optimized-for</code> +meta tag that matches the current browser, it can <em>optionally</em> show such +information in the user interface, so that developers are aware that they are +seeing a optimized page for that browser. + +</body> +</html> |
