A secure proxy like http://jumpto.com sits in your web browser and allows you to read your email when the sites blocked. I like to use that site a lot cause its keeps me anonymous. It is very important for all. There is nothing illegal about using a proxy either. All they do is let you get to the blocked website. Its only illegal when using a proxy to access an illegal site that is blocked for a reason like warez sites. Most uses of proxies are just to read email when its blocked for other reasons. You can using secure proxy. It is all the best.

It could be responsible for processing your request to connect to a file, webpage or any other service while the proxy server itself could be located anywhere in the world.

Similarly, the recipient would be oblivious of the source of the request as the only thing visible would be the request coming from the proxy server, therefore, it鈥檚 origin would be unknown. In a nutshell it allows for an indirect connection to be established between other network services. It is where the client connects to a proxy server from where a connection is requested to a different server.What is a secure proxy and how it is used in the internet?
