I'm using: symfony/1.1.4, Apache/2.2.9, nginx/0.7.16
I've problem when using nginx + apache.
Communication between nginx and apache are using HTTP/1.0. But symfony response is not correctly. Symfony set HTTP-version to HTTP/1.1. After that, Apache may used transfer encoding chunked (in my test, when response body is bigger than 9kb). And response content will have trash, because nginx waiting for HTTP/1.0 response.
I think you may use patch from:
http://trac.symfony-project.org/ticket/2817
Or extend API for sfWebResponse.
