A surrogate server, or altogether a factor, is a computer that acts as an mediator between the user and the target server. Key, the patient connects to the proxy server and requests the required resource located on another server. As a remedy for exempli gratia, 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, look up network exhibit, and access “isolated” resources. Individuals use proxies to anonymize above or bypass access restrictions.
Proxy process
Proxy technique
When talking more a factor, we usually assuredly a guide proxy server. Welcome's assume that we are making a petition, representing exemplar, fatiguing to suitable for to GitHub - enter the URL, press Enter. The substitute does not join us to GitHub straight away, but intercepts the kith and updates the solicit contentment next to removing the incoming IP and changing the header. As a result, GitHub believes that the demand came from another computer and sends the necessary information not to us, but to the surrogate server. The surrogate takes the GitHub bumf, verifies and sends the data to our computer.
How are representative servers used?
Tired delegate uses:
increasing network care at near encrypting requests;
preventing the interception of private message;
blocking malicious sites and advertising;
caching sites to save [url=https://www.linkedin.com/pulse/mua-proxy-gi%25C3%25A1-r%25E1%25BA%25BB-kh%25C3%25A1m-ph%25C3%25A1-s%25E1%25BB%25A9c-m%25E1%25BA%25A1nh-c%25E1%25BB%25A7a-socks5-v%25C3%25A0-http-schmidt-64psc]proxy mua[/url] above;

domain blocking;
monitoring and logging интернет requests;
testing интернет resources when accessed from different IPs.

What are the types of surrogate servers?
How a representative server works: the simplest excuse achievable
On the level delegate is the simplest type; the agent server settings are not monotonous registered in the browser. A transparent delegate modestly intercepts entering HTTP traffic. The owner gets the feeling that he is surfing the Internet without a surrogate server. Use anyhow: filtering diversion websites in an eye-opening network.
An anonymous delegate not in any way transmits the patient's IP address to the aim resource. A gentle chance if you don't lack targeted advertising to track you or your location. A excessive anonymity representative does not cable any IP lecture or particular evidence and does not equalize identify itself as a proxy. During enterprise, the IP oration changes periodically - this allows on paramount confidentiality. The TOR browser uses this genus of proxy server. Because IP changes, it is bloody obstructive to dog the provenience of requests.
