[opencms-dev] handle404 appears on every 404 page within the export folder

Fri Aug 27 21:37:13 CEST 2010

Sorry I dont have a publically available url but the export processes does work. For example I could have this URL:
http://www.test.com/export/doesexist.gif

If I delete "export/doesexist.gif" from the RFS then its created again as soon as I visit "http://www.test.com/export/doesexist.gif".

When I attempt to go to a URL that contains the export path and the file really doesnt exist on either the VFS or RFS. It causes me to get a 404 page that mentions /handle404 e.g http://www.test.com/export/doesnotexist.gif

I installed OpenCms as the Root and followed this because I am using mod_proxy with mod_proxy_ajp and mod_proxy_balancer:
http://www.opencms-wiki.org/Avoiding_/opencms/opencms_in_the_URL_%28apache_%2B_mod_proxy%29

This means my virtual host looks like this:
< VirtualHost *:80>
    < Directory "D:/Program Files/Apache Software Foundation/Tomcat 6.0/webapps/ROOT/">
        Order allow,deny
        Allow from all
    < / Directory> 
    ServerName test.co.uk
    DocumentRoot "D:/Program Files/Apache Software Foundation/Tomcat 6.0/webapps/ROOT/"
    ErrorLog logs/error.log

    # Log only non-redirect requests in "normal" log file
    SetEnvIf Request_URI "\/opencms\/*" redirect
    CustomLog logs/test.co.uk-access.log common env=!redirect

    RewriteEngine     on
    RewriteLog logs/test.rewrite.log
    RewriteLogLevel 9

    # Redirect all request to non-existing file in the export directory to OpenCms which will generate the files "on the fly"
    RewriteCond       %{REQUEST_URI}                                            ^/export/(.*) [NC]
    RewriteCond       "%{DOCUMENT_ROOT}%{REQUEST_FILENAME}"                     !-f
    RewriteCond       "%{DOCUMENT_ROOT}%{REQUEST_FILENAME}/index_export.html"   !-f
    RewriteRule       .*     balancer://mycluster/handle404?exporturi=%{REQUEST_URI}&%{QUERY_STRING} [P]     

    # Also redirect all other 404 errors to OpenCms
    ErrorDocument     404                                /system/shared/handle404.html

    ProxyPass         /opencms/                 !
    RedirectPermanent /opencms/                 http://test.co.uk/

    ProxyPass         /resources/               !
    ProxyPass         /export/                  !

    ProxyPass         /                         balancer://mycluster/opencms/
    ProxyPassReverse  /                         balancer://mycluster/opencms/
< / VirtualHost>
