Proxy Servers Were Created To Make Connections With Other Networks.

Proxy servers are called special-purpose computers that enable customers to create an indirect connection with other network services through a network of computer services. If you use a proxy, the first client, the connection file request to another server or other resource, you can connect to the proxy server. By connecting to a specific server from the cached resource is available through the Service. Client requests or server responses, in some cases may have been changed. After the proxy server describes the different types.

• Web Proxy

Web proxy is a proxy for common applications. The Web pages available on remote Web servers and file, we use a cache nearby. In this way, local clients can access information faster and more reliably.

Web-based URL of the proxy server to search the local cache or a specific URL is requested Web resources. If he is returned immediately to the local cache the document. In other cases, the server requests a page on a remote server, returns it to the client keeps a copy in the cache. Expiration algorithm, the access history is used to remove the document from the cache depends on the size and age. Least frequently used (LFU), and at least show (LRU) for use in this case, two algorithms are used in expires. Least frequently used documents are removed by LFU, at least recently used documents are removed by the LRU.

CGI proxy is a special web proxy. These are a special type of website that allows customers to access the desired site. To implement the proxy, or PHP will use the CGI.

Content of the Web page, Web-based filtering proxy in the case of some. May possibly reformat the page to block inappropriate content on the site mentioned by others. These types of servers can be applied in order to intercept the content of other viruses and in a remote page.

• Transparent proxy server

The transparent proxy to reveal his identity via HTTP header will be available based on IP addresses. These servers are caching the web site but they do not provide anonymity features what. However, using a transparent proxy, may lead to a simple IP ban.

• distortion of the proxy server

He will reveal himself as a proxy server using the HTTP header, provides the correct IP address when requested.

• Anonymous proxy servers

He will reveal his identity as a server, but does not provide the IP address of the source. However, to identify this type of server, it has a lot of anonymity provided by the customer.

• High-anonymous proxy server

These types of servers are not identifiable. It is also illegal to give an IP address via HTTP header, they do not provide the IP address of the source. This explains that you can use to hide the IP addresses of computers from which different types of proxies. But to turn to a computer using only the IP address of another device, it may be useful in some cases.
