Example of a successful reverse proxy to APEX using Apache and Oracle HTTP

Question

If this helps anyone, I was able to set up a reverse proxy to APEX with Apache running on the reverse proxy server and Oracle HTTP server and APEX 3.2 on the APEX hosting server. I want to post this due to there is no
documentation on this that I can find. Oracle Metalink could not produce any "How To" document either.
On the reverse proxy server in the httpd.conf file:
ProxyRequests Off
SetEnv force-proxy-request-1.0.1
SetEnv proxy-nokeepalive 1
ProxyPassReverse /pls/apex/ http://apex_server:8080/pls/apex/
ProxyPass /pls/apex/ http://apex_server:8080/pls/apex/
ProxyPassReverse /i/ http://apex_server:8080/i/
ProxyPass /i/ http://apex_server:8080/i/
AddType text/xml .xbl
AddType text/x-component .htc
OR
ProxyRequests off
RewriteEngine On
RewriteRule ^/pls/apex/(.*)$ http://apex_server:8080/pls/apex/$1 [P,NE]
ProxyRequests off
ProxyPassReverse /i/ http://apex_server:8080/i/
RewriteEngine On
RewriteRule ^/i/(.*)$ http://apex_server:8080/i/$1 [P,NE]
And in the Oracle HTTP server httpd.conf file of the APEX hosting server:
NameVirtualHost 999.99.99.9:8080
<VirtualHost 999.99.99.9:8080>
ServerAdmin [email protected]
DocumentRoot "/u01/app/ora11g/product/11.1.0/http_1/ohs/htdocs"
ServerName reverse_proxy_server.com
</VirtualHost>

Here is what I saw :
I have one Web Server 7.0 instance with the following obj.conf :
<Object name="default">
<If $uri =~ "/xyz">
NameTrans fn="map" from="/" name="reverse-proxy-/xyz" to="/"
</If>
<ElseIf $uri =~ "/abc">
NameTrans fn="map" from="/" name="reverse-proxy-/abc" to="/"
</ElseIf>
</Object>
<Object ppath="*">
Service fn="proxy-retrieve" method="*"
</Object>
<Object name="reverse-proxy-/abc">
Route fn="set-origin-server" server="http://server1.sun.com:80"
</Object>
<Object name="reverse-proxy-/xyz">
Route fn="set-origin-server" server="http://server2.sun.com:80"
</Object> ...When I send a request to URI :
/abc/test1.html : the request gets served from server1 from docs/abc/test1.html.
/xyz/test2.html : the request gets served from server2 from docs/xyz/test2.html
Where as when you change obj.conf to (note the change in "from" parameter in "map" SAF)
<Object name="default">
<If $uri =~ "/xyz">
NameTrans fn="map" from="/xyz" name="reverse-proxy-/xyz" to="/"
</If>
<ElseIf $uri =~ "/abc">
NameTrans fn="map" from="/abc" name="reverse-proxy-/abc" to="/"
</ElseIf>
</Object>
<Object ppath="*">
Service fn="proxy-retrieve" method="*"
</Object>
<Object name="reverse-proxy-/abc">
Route fn="set-origin-server" server="http://server1:80"
</Object>
<Object name="reverse-proxy-/xyz">
Route fn="set-origin-server" server="http://server2:80"
</Object> ...In this case when I send a request to URI :
/abc/test1.html : the request gets served from server1 from docs/test1.html.
/xyz/test2.html : the request gets served from server2 from docs/test2.html.
