Hi Joshua,

thanks for the hint with the loglevel. Now here's my httpd.conf :

ProxyRequests off
ProxyPass /sunreader/ http://localhost:8080/sunreader/
ProxyHTMLURLMap http://localhost:8080/sunreader/ /sunreader
ProxyHTMLLogVerbose On
LogLevel Debug


<Location /sunreader/>
	ProxyPassReverse /
	SetOutputFilter	 proxy-html
	ProxyHTMLURLMap	 /	/sunreader/
	ProxyHTMLURLMap	 /sunreader	/sunreader
	RequestHeader 	 unset	Accept-Encoding
</Location>

<IfModule mod_rewrite.c>
 RewriteEngine On
 RewriteLog "C:\Programme\xampp\apache\logs\rewrite.log"
 RewriteLogLevel 100
 
 # Update
 RewriteCond 	%{REQUEST_URI} !-U
 RewriteRule    ^/(.*).do  http://localhost/Portal_Update.php [L]
 
 #RewriteCond   ^/conergy/(.*).do !-U
 #RewriteRule   ^/conergy/(.*).do  http://localhost/Portal_Update.php
 
 #RewriteCond   ^/suntechnics/(.*).do !-U
 #RewriteRule   ^/suntechnics/(.*).do  http://localhost/Portal_Update.php
 
 # Portal
 RewriteRule ^/conergy/(.*).do$ http://localhost/sunreader/$1.do?mandant=conergy [R,L]
 RewriteRule ^/suntechnics/(.*).do$ http://localhost/sunreader/$1.do?mandant=suntechnics [R,L]

 .....
 
</IfModule>

Note that I have mod_proxy enabled, because I want to redirect the requests with /sunreader/... to tomcat. But I tested it also with mod_jk with no difference. 
And here's the rewrite.log

Until line 10 ( [22/Aug/2006:17:39:10 +0200] /subreq] (1) go-ahead with C:/Programme/xampp/htdocs/Portal_Update.php [OK] ) it looks fine to me.  But what makes me wonder that the Portal_Update.php site won't be displayed but instead of it only error 503. 
This is the URL I executed :
  http://localhost/conergy/Welcome.do

But only once. And because of the 'Portal' rule it is rewritten to this, what is only correct if the URL  is working :
   http://localhost/sunreader/Welcome.do?mandant=conergy

Thanks, Lothar
