I think that the Day CQ Root Mapping servlet redirects you to it configured by the rootmapping target.
Take a look at /libs/cq/core/config.publish/com.day.cq.commons.servlets.RootMappingServlet inside crxde. The rootmapping servlet configuration is for /content.html, which is allowed for / content. redirect this to your content, or if it should coexist, then create an additional JcrResourceResolverFactoryImpl configuration.
Just create config.publish/org.apache.sling.jcr.resource.internal.JcrResourceResolverFactoryImpl node below your application in the /apps/<yourappp>/config.publish/org.apache.sling.jcr.resource.internal.JcrResourceResolverFactoryImpl applications jcr: primaryType sling: OsgiConfig and add resource.resolver.mapping to yours, as the following examples demonstrate. resource.resolver.mapping = "[/ - /, / content / intranet / - / intranet - /, ....]" / ">
