Proxy ConfigurationYou can set the Address and the Port for a proxy server with the option to bypass it for local addresses. If you enable Proxy Protocol, a human-readable header is added to the request header with connection information such as the source IP address, destination IP address, and port numbers. You can use Proxy Protocol to capture the source IP of your client when you are using a non-HTTP protocol, or when you are using HTTPS and not terminating the SSL connection on your load balancer.
Ideally, proxy sites are websites that able to connect to internet resources with their connection details hidden. The proxy server sits between your computer and the servers where you are requesting resources or services. A proxy server will receive your internet connection, seek resources from the requested servers and then re-route the resources to you. The browser you use can be opened and your IP address is changed to one from the software program.
An email client is a front-end computer program or an agent that acts as a client for the email server. Mail Server: It can also be called Mail Transfer Agent (MTA) and is responsible for receiving incoming email from local users and forwarding outgoing mails for delivery. A mail server application forms the heart of a messaging system that performs all the functions to keep the mails moving over the network.
The ever changing technology is making it easier to set up these servers for use. As the use of the application scales, this method of dealing with requests becomes increasingly inefficient. The Cache Server (also known as a Caching Proxy Server) receives the the initial HTTP request from a client. It will either serve a previously cached response or will proxy the request to the Origin Server. The proxy has in restore what you really needed.
