Question

The reverse proxy provided by symfony2 is comparable to some reverse proxy applications on the market, the usability and performance of the built-in reverse proxy

Answer 1

Due to performance factors, you should consider using specialized services such as Varnish in high-load production environments. Symfony 2 provides a reverse proxy implemented in PHP for the convenience of development/testing. It was never intended to achieve any breakthrough in performance, but the significance is still significant:

• In order to provide support for application scenarios that require reverse proxy, Symfony 2 encapsulates the business logic of reverse proxy (designs corresponding programming interface).
• Professional and efficient web development requires automatic testing and continuous integration, which requires that business logic can run independently from external components such as Nginx and Varnish when needed. In short, with the reverse proxy implemented in PHP, developers no longer need to worry about configuring Varnish in the development/test environment.
• Some virtual hosts cannot install Varnish. When the load is not high, there will be no reverse proxy available.

Answer 2

= =A PHP development application framework. Reverse proxy.
Trust me, you don't want to use it.
