What is Proxy Server?

A proxy server is a machine that sits between the proxy users and the servers that they need access to. When a proxy user requests a certain remote resource using a URL, the proxy server receives this request and fetches the resource to fulfill the client’s request. This process enables the proxy server to store the requested content in a cache. Any new request that asks for information already in the cache no longer needs to be serviced by fetching it from the remote server. Instead, the new request is serviced from the cached data. In typical proxy scenarios, the purpose of a proxy server is to fetch the requested resource from the remote server, return it to the requesting user, and cache it in local drives.

Is it neccesary to have root access on your web hosts?

Website masters have a ton of responsibility to maintain their website and the subsequent links to it. Primarily, they have to figure it if they prefer to have access to all of the websites on their company server or if they prefer not to. When a webmaster has root access, he can virtually control anything stored on his server. This means he can access security information, user groups, and any file on the server. One might wonder why a webmaster wouldn’t want this access. Read on for the benefits and drawbacks to having root access.

When a webmaster opts to use a virtual private server hosting service, he’s choosing the less expensive option.
