Usages of Proxy Server

In computer networks, a proxy server is a server (a computer system or an application) that acts as an intermediary for requests from clients seeking resources from other servers. A client connects to the proxy server, requesting some service, such as a file, connection, web page, or other resource available from a different server and the proxy server evaluates the request as a way to simplify and control its complexity. Proxies were invented to add structure and encapsulation to distributed systems. Today, most proxies are web proxies, facilitating access to content on the World Wide Web and providing anonymity.

There are 3 main types of proxy’s: Forward proxy, open, and reverse proxy. A forward proxy is the same one described above where the proxy server forwards the client’s request to the target server to establish a communication between the two. An open proxy is a type of forwarding proxy that is openly available to any Internet user. Most often, an open proxy is used by Internet users to conceal their IP address so that they remain anonymous during their web activity. Unlike a forwarding proxy where the client knows that it is connecting through a proxy, a reverse proxy appears to the client as an ordinary server. However, when the client requests resources from this server, it forwards those requests to the target server (actual server where the resources reside) so as to fetch back the requested resource and forward the same to the client. Here, the client is given an impression that it is connecting to the actual server, but in reality there exists a reverse proxy residing between the client and the actual server.

Reverse proxies are often used to reduce load on the actual server by load balancing, to enhance security and to cache static content, so that they can be served faster to the client. Often big companies like Google which get a large number of hits maintain a reverse proxy to enhance the performance of their servers. It’s not a surprise that whenever you are connecting to google.com, you are only connecting to a reverse proxy that forwards your search queries to the actual servers to return the results back to you.

TLD Domain: coming your way soon

Before we get started, for those that aren’t clear with the term, what is a TLD?
It’s one of the domains at the highest level in the hierarchical Domain Name System of the Internet. Top-Level domain names are installed in the root zone of the name space, and for all domains in the lower levels, it is the last part of the domain name. For example, in the domain name www.webairy.com, the top level domain would be COM.

The Silicon Valley giant paid ‘$25m for acquisition rights’ to the .app domain. The purchase overcomes the $5m that Amazon paid for the rights to .buy last year. In fact, it’s the most any company has ever paid for a domain this far– and so it’s a pretty safe to say that Google’s got some sort of game plan. It will also likely toss the rest of the internet into the dust. Let’s think about it: over the past decade, the tech giant has become virtually synonymous with the web. You don’t “search for it”, you Google it.

Consequently, the well-being of millions of small business depend almost entirely upon the stability of Google’s search algorithms. So after its forking of over $25m on a previously unknown TLD, it only makes sense for Google to push emerging .app websites to the top of results pages. After all, Google might have quite a sum of cash, but whoever authorized that purchase is going to have to prove some sort of return on investment.

So, where does that leave us? Sitting on a precipice, it seems. As of now, unique TLD’s haven’t taken off because of one or two major roadblocks. If anybody on earth can find a way to circumnavigate those roadblocks and monetize the system, it’s going to be Google. All we can do now is wait and see what happens. But either way, it looks like we’re about to start seeing a whole lot of new TLD’s floating about on the web frankly very soon.
