I've been trying this approach, but without much success.  I can get
the initial screen, but when I hit the form button, I end up with a
URL like http://www.betterworld.us:81/seaside/test (sometimes with
additional stuff tacked on) in the browser and a Not Found error.

I've tried to follow the instructions at the link you indicated, and
have played around with many variants.  I enabled debug logging and
ProxyHTMLLogVerbose, but it didn't help much.  It showed that mod_html
was rewriting stuff in the initial page.

My current variation is (with some other tries commented out)
<VirtualHost 198.144.201.14:81>
	DocumentRoot /var/www/
	ServerName www.betterworld.us

	<Proxy *>
	Order deny,allow
	Allow from all
	</Proxy>
#	LogLevel debug
#	ProxyHTMLLogVerbose On
#	ProxyPass /upj http://localhost:9090/seaside/test
#	ProxyHTMLURLMap http://localhost:9090/seaside/test /upj

	ProxyPass /upj/ http://localhost:9090/seaside/test/
	ProxyHTMLURLMap http://localhost:9090/seaside/test /upj
	<Location /upj/>
	   ProxyPassReverse http://localhost:9090/seaside/test/
	   SetOutputFilter proxy-html
	   ProxyHTMLURLMap /seaside/test/ /upj/
#	   RequestHeader unset Accept-Encoding
	</Location>

#	ProxyPassReverse /upj http://localhost:9090/seaside/test
</VirtualHost>

A couple of points in particular have been unclear to me.  Should I
include the port number at various spots?  And should I use a trailing
slash or not?  For the rules above I entered "upj/" at the end of the
line in my browser.

Enabled modules: proxy, proxy_http, proxy_html, various cache,
headers.  I note that caching was explicitly outside the scope of the
reference you cited; Debian turns it on when proxying is requested.
ProxyRequests are off and ProxyVia is on globally.

If I could capture the traffic going between different spots
(browser-apache-seaside) I think things would be a lot clearer, but
I'm not sure how to do that.

Any ideas, either for how to debug this or how to solve it?
