Acronym: AOLserver Dynamic Pages
ADP is the primary method of providing dynamic content on AOLserver.
ADPs contain a mixture of TCL and HTML, with the TCL code being parsed and evaluated by AOLserver as it delivers the page. ADPs may invoke other ADPs (using ns_adp_include) and thereby build up libraries for common elements and subsections of a page like title headers, menu and navigation bars, and footers, as well functional modules like acess validation or database queries.
The TCL code in an ADP is contained within <% %> pseduo-tag pairs. A modified format, <%= %>, displays the results of the TCL code. A very simple ADP would be:
<html>
<head>
<title>My Clock</title>
</head>
<body>
<p>
The time is now <%= [ns_httptime [ns_time]] %>.
</p>
</body>
</html>
