Please help! Am I asking in the wrong forum?
I have now also tried with mod_jk (not mod_jk2) and it is the same problem:
as soon as I turn on Apache Includes the page stops working (but only when
it comes from Tomcat via mod_jk, it works perfectly in Tomcat).
Could someone using Apache2 and mod_jk installed (prefrebly mod_jk2) try
this jsp page with and without includes on (in Apache2) and tell me if it
works or not for them?
<%@ page language="java" %>
<html>
<head>
<title>Test</title>
</head>
<body>
<pre>
<%
for (int i = 0; i < 5000; i++) {
out.println("<table><tr><td>i = "+i+"</td></tr></table>");
}
%>
</pre>
</body>
</html>
Just put it in Tomcat's examples/jsp folder and add the following lines to
Apache Httpd2 conf file.
<Location "/examples/">
SetOutputFilter Includes
</Location>
If I do it IE the browser tries to reload the page a couple of times before
saying "The page cannot be displayed" Opera displays a page which is
corrupted.
I have been trying to figure out if it is the Httpd includes (which works
fine for everything except stuff from Tomcat) or the jk connection (which
works fine as long as Includes are off) that is at fault here but getting
nowhere...
Thanks in advance
