Why proxy server is used?

A proxy server may be used to access some websites that are being filtered.

You can use proxy server to access some content which does not exist in your country while this content would be blocked in your local ISP but it would be available on proxy servers based in another country. Thus, it provides protection against certain types of censorship and filtering.

Why would a hacker use a proxy server?

Why wouldn't they just use their own?

Is there any advantage to using a web proxy vs creating your own? I'm not interested in what this "hacker" is "doing" with this server (if he or she has an interest). ? In most cases you are right, they wouldn't. Proxy servers are used if they want anonymity, so that nobody knows who they are or what they are doing.

But on the other hand. For a proxy server, it is only useful if a number of users need access to it simultaneously. So if a web shop that offers VPN-access to their users can offer access via a proxy at no extra cost, it's probably worth it. In general the biggest cost is the hardware (server, network-router), that needs to be dedicated for it. But a home-user doesn't even need a proper server or dedicated hardware (well apart from the router) - as long as the connection is fast enough.

If it doesn't fit their needs, they won't. So if I see myself an attacker, I will only make something that I will use personally. I wouldn't make something my boss or my brother would use. (At least not without changing my attitude.) So I'd do it the other way around and I wouldn't make something my boss or my brother use.

As long as we are talking about proxies, some will be targeted by the police or others might just try something random. So why let them connect through that one proxy? As long as it works good for us, why bother with additional connections? Some proxies won't work as well as others. One of my clients uses a free-proxy based in Sweden. I told them, I can probably do a cheaper, faster, good VPN-connection for them, but I don't know if the IP-address will then be accessible. They couldn't care less and wanted a free service anyway.

What is an example of a proxy server?

I think this one may help you: I think it explains it quite well.

To be a bit more formal, a "proxy server" is a system which has two or more connections to the internet and acts as a firewall for requests from clients. It relays incoming requests to other servers on the internet. Clients connect to the proxy server and have their requests forwarded to the target server.

Examples of a proxy server: Web browsers: The web browser (Internet Explorer, Chrome, etc.) has a built-in proxy which forwards requests to a web server.

Mail clients (Eudora, Thunderbird, Outlook Express, etc.): Clients that send email will have their requests forwarded to a mail server. Servers: In the case of FTP servers, the proxy server could be another FTP server, and would accept the incoming connection and then forward the request to the real FTP server. Web servers: Many web servers can be configured with proxies. A web browser will connect to a proxy server which sends the request on to the correct web server.

Applications: Proxy server functionality is often built into applications to allow users to access resources behind a firewall. You can, for instance, configure your application to work through a proxy server rather than directly to a remote server.

An example is the Tor Proxy.

What happens if you don't use a proxy server?

If you connect to the internet without the use of a proxy server, then your computer's IP address (the number assigned by your ISP) will be stored in your browser's cache. This means that if you are on the same network again later and the IP address is still listed in your browser cache, then you may bypass any proxy servers at the ISP (for example, the ones at your home or office).

A good way to keep this problem from happening is by always connecting through a proxy server. What is a proxy? A proxy server is a program that rewrites an IP address and/or a port. The most common use for a proxy server is to allow multiple computers connected to a single LAN to use a single IP address for the internet. The computers connected to this single LAN could behind firewalls (at a company, for example), and yet they could still access the internet.

All major browsers, including Internet Explorer (on Windows), Google Chrome, Firefox, Safari and Opera, have a proxy server built in. Firefox has support for proxies through the add-on called the "Proxy Auto-Detection and Configuration Tool." Opera also has support for proxies.

There are also plenty of proxy servers available for download at Proxy sites like: Why do I need a proxy? To bypass firewalls, in order to maintain privacy and freedom of access, and to make it easier to connect to multiple networks that may have different kinds of connection configurations (for example, a Wi-Fi and a dial-up). How do I use a proxy? Open the browser of your choice. Then, go to Proxy Sites. (For example: go to this site and click on "Select a proxy"). Select a proxy server. For example, here are some proxy servers that support IE9: Windows 7 and Windows 8. The settings for this version of IE are stored in a special folder that you can access by going to: (Go to C:UsersYourNameHereLocal SettingsApplication DataInternet Explorerieproxy.dat) and opening the file ieproxy.dat)
