HTTP 302 is not an error: it is a redirection. The thing which is wrong with that is the Location header which makes a reference to a server which is not known to the clients: webserver-internal. In other words, the backend server tells the browser to make a request for http://webserver-internal/dealer/sso/login. The browser tries to reach webserver-internal but fails to do so.
In order for the Location header in the response to be rewritten, you need to add the following line to your configuration:
ProxyPassReverse / http://webserver-internal/
Then, when the 302 response reaches the browser, the Location header will contain http://webserver/dealer/sso/login.
You can probably remove the line
ProxyPassReverse / http://ip-address/
although it probably does not hurt to leave it.

Subject: RE: [users@httpd] apache 2.0 as reverse proxy using mod_rewrite
Ok I made a mistake in the initial question
When someone goes to https://webserver it has to be redirected to http://webserver-internal/dealer/start
You were right on https://login it has no subdirectory redirect and this works without the rewrite...
I got the following 302 found error from the browser (with header display tool)
HTTP/1.1 302 Found
Date: Fri, 24 Jun 2005 10:43:25 GMT
Server: Apache/1.3.26 (Unix)
Location: http://webserver-internal/dealer/sso/login;DAX_SESSION_COOKIE=C7kFPYZikF3EPG3aKAHBhK2F8JTlnu3lZPk1pcX6A22NluGlzkFK!398064258!175689490!8000!7002
Set-Cookie: DAX_SESSION_COOKIE=C7kFPYZikF3EPG3aKAHBhK2F8JTlnu3lZPk1pcX6A22NluGlzkFK!398064258!175689490!8000!7002; path=/dealer
Content-Type: text/plain; charset=UTF-8
Connection: close
Transfer-Encoding: chunked
So it goes to the right server but it ends at dealer/sso.... With the following rewrite rule in the virtual host webserver:
<VirtualHost ip-address:443>
ServerAdmin webmaster@webserver
ServerName webserver
ProxyPass / http://webserver-internal/
ProxyPassReverse / http://ip-address/
SSLEngine on
SSLCertificateFile /etc/httpd/conf/ssl.crt/webserver.crt
SSLCertificateKeyFile /etc/httpd/conf/ssl.key/webserver.key
ErrorLog logs/error_log_webserver
TransferLog logs/access_log_webserver
RewriteEngine On
RewriteRule ^/$ https://webserver/dealer/start [R,L]
</VirtualHost>
