Hi, all. Is there a way to share configuration between multiple backends?
The use case for this is that we would like to configure different response headers for different parts of our application, based on the request URL, but otherwise route traffic the same way. Specifically, we want to specify 'X-Frame-Options: ALLOW-FROM <some site>' across most of the application, but just use 'X-Frame-Options: DENY' on the admin area. We could do this, of course, by sending the admin traffic to a different backend, and setting the response header differently in that backend, but then we'd need to repeat our server configuration, which is otherwise the same. Something like this: frontend foo listen x.x.x.x acl admin url_beg /admin default_backend foo use_backend foo_admin if admin backend foo rspadd "X-Frame-Options: ALLOW-FROM some-trusted-server.com" <potentially complex configuration goes here> backend foo_admin rspadd "X-Frame-Options: DENY" <same configuration goes here> To reduce the duplication, is it possible to have one backend delegate to another, or specify a named list of servers that can be referenced from different places? Thanks in advance. Thrawn
