As seen on comp.lang.python, it is apparently possible to run Web servers "behind" Apache. Since WebKit now has a Web server component, this should provide an interesting solution for serving mixed content.
Of course, even without using any built-in Web serving capability provided with WebKit, it's probably possible to run two Apache servers and to "pipeline" them. (I've seen worse things done in real life!)
Holger Krekel wrote that the configuration option is ProxyPass:
ProxyPass /sub/name/ http://localhost:7000
Written in your domain's configuration section, this would pass requests such as:
http://www.yourdomain.net/sub/name/something
to:
http://localhost:7000/something
