The #()# directive allows you place an expression within the body of a CSP page. This expression is evaluated on the server when the page is requested by a client. The result of the expression is sent to the client as part of the HTTP response.
For example, the following HTML:
The value of <I>x</I> is: <B>#(x)#</B>
Is equivalent to:
<SCRIPT LANGUAGE="CACHE" RUNAT="SERVER"> Write "The value of <I>x</I> is: <B>",x,"</B>" </SCRIPT>
