A delegate server, or simply a surrogate, is a computer that acts as an mediator between the user and the quarry server. First, the customer connects to the proxy server and requests the required resource located on another server. On prototype, email or html page. The agent then either connects to the specified server and obtains the resource from it, or returns the resource from its own cache.
Companies permit proxies to guarantee fastness, improve network performance, and access “remote” resources. Individuals from proxies to anonymize see trade or bypass access restrictions.
Representative approach
Surrogate process
When talking about a proxy, we regularly medium a guide agent server. Welcome's imagine that we are making a request, championing exemplar, trying to decamp a return to to GitHub - begin the URL, smooth Enter. The substitute does not stick us to GitHub instantly, but intercepts the connection and updates the request essence next to removing the incoming IP and changing the header. As a result, GitHub believes that the entreat came from another computer and sends the necessary details not to us, but to the substitute server. The proxy takes the GitHub information, verifies and sends the evidence to our computer.
How are agent servers used?
Tired delegate uses:
increasing network care on encrypting requests;
preventing the interception of intimate message;
blocking malicious sites and advertising;
caching sites to redeem proxy tĩnh số lượng lớn movement;
monitoring the exploit of a network canal;
lands blocking;
monitoring and logging web requests;
testing интернет resources when accessed from unalike IPs.

How a proxy server works: the simplest excuse tenable
See-through representative is the simplest classification; the proxy server settings are not stable registered in the browser. A crystal clear representative plainly intercepts entering HTTP traffic. The alcohol gets the atmosphere that he is surfing the Internet without a representative server. Bring into play anyhow: filtering entertainment websites in an educational network.
An anonymous proxy at no time transmits the client's IP direct to the target resource. A good option if you don't require targeted advertising to track you or your location. A high anonymity proxy does not transmit any IP location or personal evidence and does not equalize identify itself as a proxy. During operation, the IP talk to changes periodically - this allows on paramount confidentiality. The TOR browser uses this personification of proxy server. Because IP changes, it is bloody ticklish to copy the outset of requests.
