Apache ASP

Server pages

Server pages embed active code in HTML pages
Examples:
- Microsoft's ASP
- Apache ASP
- Perl Template module
- Java Server Pages
Apache ASP has Perl as preferred scripting language

Embedding code

Expressions can be embedded and are evaluated at runtime
Typical syntax for expression embedding
```
      <%= expression =%>
      
```
Code can be embedded and is typically compiled or interpreted at runtime
```
      <% code %>
      
```
The code between start and end tags can span multiple lines

Simple example


  <html>
  <body>
  For loop incrementing font size: <p>
  <% for(1..5) { %>
        <!-- iterated html text -->
        <font size="<%=$_%>" > Size = <%=$_%> </f
ont> <br>
  <% } %>
  </body>
  </html>
