[opencms-dev] mod_proxy setup problems

[Shi Yusen]

If you use Apache 2.2.x, you can try the new ajp in mod_proxy.
http://httpd.apache.org/docs/2.2/mod/mod_proxy.html

Here is a sample config of www.langhua.cn, the logic behind is quite
simple:
If a uri should be proxied, then proxy it. If not, use apache.
If a uri should be prefixed with /opencms/opencms/, then add it.
If a uri should be handled by OpenCms 404 handler, then use it.
...

NameVirtualHost *:80

<VirtualHost *:80>
        ServerAdmin shijh at langhua.cn
        DocumentRoot /usr/share/tomcat5/webapps/opencms
        ServerName www.langhua.cn

        RewriteEngine on

        # The URIs don't need to proxy
        RewriteCond %{REQUEST_URI} !^/opencms/resources/.*$
        RewriteCond %{REQUEST_URI} !^/export/.*$
        RewriteCond %{REQUEST_URI} !^/forum/.*$
        RewriteRule !^/opencms/opencms/.*$ /opencms/opencms
%{REQUEST_URI} [PT]

        # Keep OpenCms handle404 function work in the integration
        RewriteCond %{REQUEST_URI} ^/export/.*$
        RewriteCond "%{DOCUMENT_ROOT}%{REQUEST_FILENAME}" !-f
        RewriteCond
"%{DOCUMENT_ROOT}%{REQUEST_FILENAME}/index_export.html" !-f
        RewriteRule .* /opencms/opencms/handle404?exporturi=
%{REQUEST_URI}&%{QUERY_STRING} [R]

        # If the request starts with /${WEBAPP_NAME}/resources, delete
the /${WEBAPP_NAME} prefix
        RewriteCond %{REQUEST_URI} ^/opencms/resources/.*$
        RewriteRule ^/opencms/(.*)$ /$1 [PT]

        ProxyRequests Off 
        ProxyPreserveHost On
        ProxyPass /opencms/opencms balancer://cluster/
stickysession=jsessionid 
        <Proxy balancer://cluster/> 
                BalancerMember ajp://127.0.0.1:8009/opencms/opencms
        </Proxy> 

        # Multiple proxies
        ProxyPass /forum balancer://forumcluster/
stickysession=jsessionid 
        <Proxy balancer://forumcluster/> 
                BalancerMember ajp://127.0.0.1:8009/forum
        </Proxy> 

</VirtualHost>

You can also add Location and other configs in the VirtualHost.

Tomcat server.xml config:
<Connector port="8009" emptySessionPath="true" URIEncoding="UTF-8" 
   enableLookups="false" redirectPort="8443" protocol="AJP/1.3" />

OpenCms opencms-importexport.xml config:
			<rfs-prefix>/export</rfs-prefix>
			<vfs-prefix></vfs-prefix>
