## 10.5. Echo

Finally, we can `echo` a limited number of environment variables: `DATE_GMT`, `DATE_LOCAL`, `DOCUMENT_NAME`, `DOCUMENT_URI`, and `LAST_MODIFIED`. The file echo.shtml is:

>     Echoing the Document_URI <!--#echo var="DOCUMENT_URI"-->
>     Echoing the DATE_GMT <!--#echo var="DATE_GMT"-->

and produces the response:

>     Echoing the Document_URI /echo.shtml
>     Echoing the DATE_GMT Saturday, 17-Aug-96 07:50:31
