Has recent apache2 upgrade screwed something

[Alan Chandler <alan@chandlerfamily.org.uk>]

My web site, see address in my signature has just started going wrong 
after the a recent upgrade to apache2 that occured on my etch system a 
few days ago.  Unfortunately I did some other things as well at the 
time and I can't isolate the fault.  Any help would be much 
appreciated - even as to how I can debug what it going on.

When I access url http://www.chandlerfamily.org.uk the browser hangs as 
though apache is not responding

However, it should be rewriting this url to 
http://www.chandlerfamily.org.uk/blog/app

as per this snippet of the config

<VirtualHost  home.chandlerfamily.org.uk:80 >

        Include /etc/apache2/sites-available/www-common
        RewriteRule ^/$ /blog/app       [PT]
</VirtualHost>

(where www-common switches the RewriteEngine on )


This rewrite appears to work, because when I do access the non 
responding url, the apache2 log file shows I have tried to access the 
rewritten url


When I access http://www.chandlerfamily.org.uk/blog/app explicitly the 
web site displays

The other point to make, is that /blog/app is not actually serviced by 
apache.  Through a JKmount it is passed back to tomcat for processing

This is some snippets from www-common

        ServerName www.chandlerfamily.org.uk

        DocumentRoot /var/www/chandlerfamily

        RewriteEngine   on
...
# define which URLs get passed to tomcat
        JkMount         /blog/* tomcat
