A proxy server, or simply a substitute, is a computer that acts as an go-between between the purchaser and the goal server. Win initially, the shopper connects to the representative server and requests the required resource located on another server. On example, email or html page. The surrogate then either connects to the specified server and obtains the resource from it, or returns the resource from its own cache.

Companies privilege consumption proxies to make sure guarantee, repair network performance, and access “irrelevant” resources. Individuals use proxies to anonymize above or avoid access restrictions.

Proxy process
Factor technique
When talking more a representative, we usually medium a instruct delegate server. Betray’s conceive of that we are making a requisition, championing exemplar, trying to suitable for to GitHub — log the URL, press Enter. The delegate does not connect us to GitHub speedily, but intercepts the reference and updates the solicit content by removing the entering IP and changing the header. As a come about, GitHub believes that the demand came from another computer and sends the necessary information not to us, but to the substitute server. The representative takes the GitHub information, verifies and sends the data to our computer.

How are representative servers used?
Common proxy uses:

increasing network protection on encrypting requests;
preventing the interception of private message;
blocking malicious sites and advertising;
caching sites to protect gói proxy xoay traffic;
monitoring the drink of a network channel;
lands blocking;
monitoring and logging интернет requests;
testing интернет resources when accessed from unusual IPs.

What are the types of substitute servers?
How a delegate server works: the simplest excuse possible
On the level substitute is the simplest classification; the surrogate server settings are not monotonous registered in the browser. A transparent representative really intercepts new HTTP traffic. The user gets the feeling that he is surfing the Internet without a proxy server. Put anyway a lest: filtering diversion websites in an educational network.

An anonymous substitute in no way transmits the patient’s IP address to the target resource. A gentle opportunity if you don’t require targeted advertising to follow you or your location. A high anonymity delegate does not telephone any IP address or in person evidence and does not equalize recognize itself as a proxy. During project, the IP address changes periodically — this allows in compensation greatest confidentiality. The TOR browser uses this genus of factor server. Because IP changes, it is unusually ticklish to record the outset of requests.
