Proxy And Details by Lucifer
What is Proxy ??
Its most common purpose is the proxy server , used to intercept network connections that a client makes a target server, for several possible reasons such as security, performance, anonymity, and so on.
What is Proxy Server ??
A proxy is a program or device that makes Internet access a task rather than another computer. A proxy is an intermediate point between a computer connected to the Internet and the server you are accessing. When we surf through a proxy, we're not actually going directly to the server, but we make a request on the proxy and it is he who connects to the server that we want to access and returns the result of the application.
What do you mean by HTTP Server ??
This type of server operates at the Application Layer of TCP / IP . The communication port of entry should be 80 / http according to IANA . 1 While generally tend to use other communication ports like 3128, 8080 or 8085.
What do you mean by HTTPS Server ??
This type of server operates at the Application Layer of TCP / IP . Unlike an HTTP server, works on encryption technologies such as SSL / TLS to provide enhanced security and anonymity. The port used varies, but should be 443 / https .
What is Web Service Proxy or Proxy ??
Its operation is based on HTTP and HTTPS proxy, but the key difference is that the request is made through a Web Application Server embedded in HTTP , which is accessed by an address DNS , that is, a website that allows these services .
What is a Proxy Cache ??
His method of operation is similar to an HTTP or HTTPS proxy. Its function is to preload the web content requested by the user to accelerate the response to future requests for Web the same information from the same machine or another.
Some of the disadvantage of Proxy are
In general (not just computers), use of an intermediary can cause:
Abuse . By being willing to receive requests from many users and answer them, you may do some work that does not touch. It therefore has to control who has access and who not to their services, which is usually very difficult.
Loading . A proxy is to do the work of many users.
Intrusion . It's a step between origin and destination, and some users may not want to go through the proxy. And if you make less cache and stores copies of data.
Inconsistency . If you cache, you may be wrong and give an answer when there is an ancient latest in the target resource. Actually, this problem does not exist with servers current proxy, and that connect to the remote server to verify that the cached version is still the same as the one on the remote server.
Irregularity . The fact that the proxy represents more than one user is problematic in many scenarios, in particular those which require a direct communication between a sender and a receiver (such as TCP / IP ).
