There
are two common errors that you can make when using Server Side Includes.
First, you should not forget the "#" sign:
<!--echo var="REMOTE_USER"-->
Second, do not add extra spaces between the "-" sign and the
"#" character:
<!-- #echo var="REMOTE_USER"-->
If you make either of these two mistakes, the server will
not give you an error; rather it will treat the whole expression
as an HTML
comment.
