I've posted this question to another forum but no one there seems to have an answer. I"ve been reading a bit about proxy servers lately. I've been told that there are two reasons to use a proxy server. The first for security and the second for a faster connection. I'm a bit confused with both of these uses. I'll start with the security. If a computer is connected to a proxy server, why is it anymore difficult to track the IP address of the respective computer. Does it take longer for it to track the IP address? On this note is it possible and would there be a point to route a proxy server to another(that might be a stupid question...). If a computer has to go through a server to get to another server wouldn't that take longer since it has to access two parties instead of one? If a proxy server is connected to multiple computers at the same time wouldn't that make the server lag and become less efficient than just a regular connection to a website?
