This is slightly off-topic, but you may want to look into OpenSymphony's
OSCache module. It provides a variety of caching options for JSP and it's

> Hello,

> My current setup is that i have apache running on port 80, with following
config:
> <VirtualHost 145.58.67.8>
> ServerName eduard.omroep.nl
> ServerAlias eduard
> ErrorLog /var/proxy/logs/errors
> CustomLog /var/proxy/logs/access common

> ProxyPass / http://localhost:8080/
> CacheRoot "/tmp/proxy"

> Furthermore the orionserver is running on port 8080, and has the following
'special' settings:
> <frontend host="eduard.omroep.nl" port="80" />

> For the testing purposes i have the following jsp page:
> <%@ page session="false" %>
> <%! int counter = 0; %>
> <%!
> // return a time back, which is +15 seconds..
> public long getLastModified(HttpServletRequest request) {

> Will expire at:<%= expires %><br />
> Expire time in seconds:<%= seconds %><br />
> Count:<%= counter++ %></p>
> </body>
> </html>

> Everytime i request the page, the counter is increased, but this is not
what i want. I want to increased at an maximum of 1 time in the 15 seconds.
> Can somebody help me how to accomplish this, or possible otherways to
