It is possible to use an if statment with SSI files. The conditional directives are if, elif, else, endif. It is also possible to do pattern matching using /pattern/. Here is an example that tests if this file was last modified on a weekday
<!--#if expr="${LAST_MODIFIED} = /Sat/" --> <p>Not modified on a weekday; modified on Saturday <!--#elif expr="${LAST_MODIFIED} = /Sun/" --> <p>Not modified on a weekday; modified on Sunday <!--#else --> <p>Modified on a weekday <!--#endif -->
Modified on a weekday
<!--#if expr="${LAST_MODIFIED} = /Sat/" --> <!--#set var="LAST_MODIFIED" value="Monday" --> <!--#elif expr="${LAST_MODIFIED} = /Sun/" --> <!--#set var="LAST_MODIFIED" value="Monday" --> <!--#else --> <!--#set var="LAST_MODIFIED" value="Sunday" --> <!--#endif -->
<!--#if expr="${LAST_MODIFIED} = /Sat/" --> <p>Not modified on a weekday; modified on Saturday <!--#elif expr="${LAST_MODIFIED} = /Sun/" --> <p>Not modified on a weekday; modified on Sunday <!--#else --> <p>Modified on a weekday <!--#endif -->
Not modified on a weekday; modified on Sunday
