+<p>
+By default, the first (left-most) question mark in the substitution
+delimits the path from the query string. Using the [QSL] flag instructs
+<directive module="mod_rewrite">RewriteRule</directive> to instead split
+the two components using the last (right-most) question mark. </p>
+
+<p>
+This is useful when mapping to files that have literal question marks in
+their filename. If no query string is used in the substitution,
+a question mark can be appended to it in combination with this flag. </p>
+
+<p> This flag is available in version 2.5.0 and later.</p>
