What are proxies for?The most common use of an anonymous proxy server is that it allows infinite downloads and overcomes limitations imposed by servers or websites. A proxy is simply a software program with the utility of "giving service", that is, it allows some access to a machine (which is running the program) from others, but in this case, the brain functioning the service is not the final destination in communication, but only a gateway that facilitates traffic to other parts of a network.
If you want to buy a private proxy and this seems a little confusing, you allowed find useful some basics. From a computer connected to the Internet, you can run a web server, allowing former computers (clients) to connect. This consists of a particular protocol and it is linked to the information contained on a hard drive. In this case the server, your brain is the final destination of the communication required for those remote computers. However, if you install a proxy server on your machine, you don’t want other computers to pore over your hard drive, all in all, your PC will be simply acting as a gateway.
A prototypal situation in which it may be necessary to install a proxy server, is when you have a network of assorted computers and only one of them has access to the Internet possible. Leaving aside the fact that there are better systems to do so, there is always an option connect with other computers. So, yes, you can Buy Private Proxies for this purpose.
In this case, in your network, the PC that would accept direct access to the Internet would be the one amidst the installed proxy, while the others will access that computer asking you to give them ready to the Internet. The only computer that will have a public IP on the Internet endow be the one running the proxy, the others will breathe "visible" to the Internet, because it is as if there is only one computer surfing.In this example, the proxy server would have a just private utility, accessible only from the computers that are on your network, and nothing else.
Is there any public utility?
Proxy servers are open networks in Internet for a long time. One of the possibilities of "action" of these devices is to store on your hard drive (or other storage device) web pages that the client computers are asking, even if Pages on any Internet site. The "cached" file is not because exotic as it may seem, even our computers keep saving the cache pages we visit, then that if we return to a page we have seen before in the same session, the paginate will load faster, since the browser want skim it to your hard drive, where it is stored.
Depending on how you have configured your browser, these pages stored on our team, will be usable to other sessions or not. The difference is if you activate to empty the disk cache every time you close the browser (in which case it will be available from one session to another) or not activated (and then it will be available between sessions).
