-<p>Notice that <em>expression</em> is first parsed into an internal machine
-representation and then evaluated in a second step. Actually, in Global and
-Per-Server Class context <em>expression</em> is parsed at startup time and
-at runtime only the machine representation is executed. For Per-Directory
-context, specifically in a .htaccess context, this is different: here <em>
-expression</em> has to be parsed and immediately executed for every request.</p>
+<p>The <em>expression</em> is parsed into an internal machine
+representation when the configuration is loaded, and then evaluated
+during request processing. In .htaccess context, the <em>expression</em> is
+both parsed and executed each time the .htaccess file is encountered during
+request processing.</p>
