The default would be a non-APR HTTP connector on port 8080. You could
just look in conf/server.xml for all <Connector> elements that haven't
been commented-out and post them, here.
Regarding "APR"... have you installed any kind of native library into
your Tomcat instance? If not, then you are probably not using APR.

Both of these versions should be performing equally well.
Something interesting to do would be to install a filter that watches
your AJAX requests and reports which session is being referenced.
Something like this would work:
public class SessionIdReporterFilter
implements javax.servlet.Filter
{
private ServletContext _app;
public void init(FilterConfig config)
{
_app = config.getServletContext();
}
public void doFilter(ServletRequest req,
ServletResponse rsp,
FilterChain chain)
throws IOException, ServletException
{
if(req instanceof HttpServletRequest)
{
HttpServletRequest request = (HttpServletRequest)req;
_app.log("Got a request for " + request.getRequestURL()
"; using sessionid="
+ request.getRequestedSessionId()
"; session=" + request.getSession(false));
}
chain.doFilter(req, rsp);
}
}
Enable this in your webapp's web.xml like this:
<filter>
<filter-name>sessionIdReporter</filter-name>
<filter-class>fully.qualified.SessionIdReporterFilter<filter-class>
<description>
Reports the requested session id and resulting session used
to handle a request. Logs to the application's context log.
</description>
</filter>
<filter-mapping>
<filter-name>sessionIdReporter</filter-name>
<url-pattern>/whatever/matches/your/ajax/requests</url-pattern>
</filter-mapping>
The <filter> and <filter-mapping> elements go in web.xml before any
<servlet> or <listener> declarations.
Hope that helps,
