A delegate server, or altogether a substitute, is a computer that acts as an third party between the purchaser and the object server. Key, the client connects to the proxy server and requests the required resource located on another server. For example, email or html page. The substitute 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 security, reform network performance, and access “isolated” resources. Individuals from proxies to anonymize traffic or bypass access restrictions.
Substitute process
Proxy technique
When talking about a factor, we mainly positively b in any event a head up representative server. Let's conceive of that we are making a request, representing prototype, trying to suitable for to GitHub - document the URL, impel Enter. The substitute does not join us to GitHub instantly, but intercepts the reference and updates the request essence next to removing the arriving IP and changing the header. As a fruit, GitHub believes that the demand came from another computer and sends the of the utmost importance data not to us, but to the proxy server. The surrogate takes the GitHub information, verifies and sends the evidence to our computer.
How are agent servers used?
Stock delegate uses:
increasing network security past encrypting requests;
preventing the interception of classified information;
blocking malicious sites and advertising;
caching sites to keep proxy tĩnh ping thấp traffic;
monitoring the use of a network watercourse;
kingdom blocking;
monitoring and logging интернет requests;
testing интернет resources when accessed from unalike IPs.

What are the types of substitute servers?
How a representative server works: the simplest excuse possible
Transparent representative is the simplest group; the delegate server settings are not even registered in the browser. A transparent factor simply intercepts incoming HTTP traffic. The owner gets the atmosphere that he is surfing the Internet without a factor server. Bring into play anyhow: filtering entertainment websites in an educational network.
An anonymous delegate never transmits the patron's IP location to the aim resource. A good opportunity if you don't deficiency targeted advertising to follow you or your location. A exuberant anonymity delegate does not telephone any IP lecture or close evidence and does not equal categorize itself as a proxy. During operation, the IP address changes periodically - this allows for paramount confidentiality. The TOR browser uses this type of agent server. Because IP changes, it is bloody ticklish to record the documentation of requests. |
