Thank you. I have other questions: 1- When I configured a Reverse Proxy and want to use "ModSecurity", then I just need to install the ModSecurity on Reverse Proxy server or I must install ModSecurity on both of the Front-End and Back-End servers? 2- With ATS (Apache Traffic Server), need I to install Apache Web Server on the Front-End server? 3- Can anyone tell me what is the main difference between the Forward Proxy and Reverse Proxy?

Is it kind of load balancing or CDN? No. Whether you have one back-end server or a hundred, you have to allow for the fact that under certain circumstances the reverse proxy may not be able to contact any of them, and therefore has to return some response to the requesting client.
