404 error while accessing sicf services via apache reverse proxy

Question

Hi,
I set up an reverse proxy with apache 2.2 and try to access SICF Services via this proxy. I got the following error message from the sap system:
Service cannot be reached
The termination occurred in system SMP with error code 404 and for the reason Not found.
The selected virtual host was 0 .
What can I do?
Please select a valid URL.
If you do not yet have a user ID, contact your system administrator.
ErrorCode:ICF-NF-http-c:000-u:SAPSYS-l:E-i:NE-SSMP01_SMP_00-v:0-s:404-r:Notfound
When I access J2EE services via the proxy it works.
Is there any configuration which have to be done in the ABAP Stack for accessing Services via the proxy server?
For tests I tried to access the simple ping service ( /default_host/sap/public/ )
Thanks and best regards,
Tim

Hi Oliver,
I allready checked the SDN posts for the reverse proxy. Maybe I missed something.
The ProxyPreserveHost is on.
I redirect to the ICM. I only redirected to the J2EE for tests. This worked by the way withe the same conifiguration.
Here is my apache config:
VirtualHost *:5443>
        ServerName      domain.com
        ServerAdmin     test.de
     ProxyPreserveHost On
     #ProxyVia On
     #AllowEncodedSlashes On
Rewrite Rules
- forward sap/public/ping?sap-client=001 -> Test Ping
- Passthrough /sap/public/ping/*
- Redirect any other URL -> Test Ping
        RewriteEngine On
        RewriteRule     ^/sap/public/ping?sap-client=001$     /sap/public/ping?sap-client=001          [R,L]
     RewriteRule     ^/sap/public/(.*)                     /sap/public/$1                    [PT,L]
     RewriteRule (.*)                               /sap/public/ping?sap-client=001          [R,L]
     RewriteLog logs/rewrite_SMP.log
     RewriteLogLevel 3
Reverse Proxy to
- Disable Forward Proxy
- Allow Connections from All
- Reverse Mapping for 302 Response
- Forward / Requests to domain.com:8000
        ProxyRequests Off
        <Proxy *>
                AddDefaultCharset off
                Order Allow,Deny
                Allow from all
        </Proxy>
Forward Rules
     ProxyPass             /sap/public/ping          http://domain.com:8000/sap/public/ping?sap-client=001
     ProxyPassReverse      /                    http://domain.com:8000/
</VirtualHost>
