I have set up mod_transform as a filter in front of my proxied Plone site with the following config: FilterDeclare THEME FilterProvider THEME XSLT resp=Content-Type $text/html FilterChain THEME TransformSet /theme/compiledtheme.xsl TransformOptions +ApacheFS +HTML RewriteEngine On RewriteCond %{REQUEST_URI} !^/(theme|xdv|images|css|js|Scripts).* RewriteRule ^/(.*) \ http://localhost:8080/VirtualHostBase/http/%{SERVER_NAME}:80/Plone/VirtualHostRoot/$1 [L,P,NS] This works great for normal pages, but proxied 404 responses are not transformed. How do I instruct pass error responses through my filter chain?
