Here's an example apache virtualhost config that enables static export "on
demand" with 6.0.
It's based on our Apachae httpd / mod_proxy / Tomact configuration.

<VirtualHost *>
    ServerName test.alkacon.com
    ServerAdmin a.kandzior at alkacon.com
    DocumentRoot "/var/tomcat4/webapps/ROOT/"
    ErrorLog logs/error.log

    # Redirect all request to non-existing file in the export directory to
OpenCms which will generate the files "on the fly"
    RewriteEngine     on
    RewriteCond       %{REQUEST_URI}
^/export/(.*)  [NC]
    RewriteCond       "%{DOCUMENT_ROOT}%{REQUEST_FILENAME}"
!-f
    RewriteCond
"%{DOCUMENT_ROOT}%{REQUEST_FILENAME}/index_export.html"   !-f

http://127.0.0.1:8086/opencms/handle404?exporturi=%{REQUEST_URI}&%{QUERY_STR

    # Also redirect all other 404 errors to OpenCms
    ErrorDocument     404

    ProxyPass         /opencms/                 !
