Proxy sites are the sites designed to give you access to the world wide web keeping your identity anonymous. basically when you visit any site from your PC , the web server gets to know your IP address, which can be used to track you or whatever. however if you visit the same site via a proxy site then your IP is not revealed to that web server. proxy server requests that page on your behalf, so IP of proxy server goes and then that page is sent to you by the proxy server.
Proxy server/sites are also used to bypass the parental control or firewall. Eg in colleges/schools if social networking sites are blocked then you can use a proxy server to request facebook/any other social networking site for you. in simple words if A cant connect to B then A sends to C , C sends to B and vice versa. thus proxy site acts intermediate

A proxy server is a server (a computer system or an application) that acts as an intermediary for requests from clients seeking resources from other servers. A client connects to the proxy server, requesting some service, such as a file, connection, web page, or other resource, available from a different server. The proxy server evaluates the request according to its filtering rules. For example, it may filter traffic by IP address or protocol. If the request is validated by the filter, the proxy provides the resource by connecting to the relevant server and requesting the service on behalf of the client. A proxy server may optionally alter the client's request or the server's response, and sometimes it may serve the request without contacting the specified server. In this case, it 'caches' responses from the remote server, and returns subsequent requests for the same content directly.
A proxy server has a large variety of potential purposes, including:
To keep machines behind it anonymous (mainly for security).
To speed up access to resources (using caching). Web proxies are commonly used to cache web pages from a web server.
To apply access policy to network services or content, e.g. to block undesired sites.
To log / audit usage, i.e. to provide company employee Internet usage reporting.
To bypass security / parental controls.
To scan transmitted content for malware before delivery.
To scan outbound content, e.g., for data leak protection.
To circumvent regional restrictions.
To allow a web site to make web requests to externally hosted resources (e.g. images, music files, etc.) when cross-domain restrictions prohibit the web site from linking directly to the outside domains.
A proxy server that passes requests and replies unmodified is usually called a gateway or sometimes tunneling proxy.
A proxy server can be placed in the user's local computer or at various points between the user and the destination servers on the Internet.
A reverse proxy is (usually) an Internet-facing proxy used as a front-end to control and protect access to a server on a private network, commonly also performing tasks such as load-balancing, authentication, decryption or caching.
A forward proxy taking requests from an internal network and forwarding them to the Internet.
Forward proxies are proxies where the client server names the target server to connect to. Forward proxies are able to retrieve from a wide range of sources (in most cases anywhere on the Internet).
The terms "forward proxy" and "forwarding proxy" are a general description of behaviour (forwarding traffic) and thus ambiguous. Except for Reverse proxy, the types of proxies described on this article are more specialized sub-types of the general forward proxy concept.
