In computer networks, a proxy server is a server (a computer system or an application program) that acts as a go-between 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. The proxy server evaluates the request according to its filtering rules. For example, it may filter traffic by IP address or protocol. If the request is validated by the filter, the proxy provides the resource by connecting to the relevant server and requesting the service on behalf of the client. A proxy server may optionally alter the client's request or the server's response, and sometimes it may serve the request without contacting the specified server. In this case, it 'caches' responses from the remote server, and returns subsequent requests for the same content directly. A proxy server has two purposes:
A proxy server that passes requests and replies unmodified is usually called a gateway or sometimes tunneling proxy. A proxy server can be placed in the user's local computer or at various points between the user and the destination servers or the Internet. A reverse proxy is a proxy used as a front-end to accelerate and cache in-demand resources (such as a web page).

Q. k9 has been great, till my kids heard about proxy servers. How do i stop this ? Asked by =42 - Tue Apr 15 01:38:20 2008 - - 4 Answers - 0 Comments A. You pretty much cant. They did a consumer report type of comparison of half a dozen parental blocks and they all can be defeated by your kids in under an hour including all the goodies you put in to monitor their activities. keyloggers , pages visited etc...The only way to stop them is complete denial of internet access but that isnt fair to them. They could install a web browser on a flash stick or get a LIVE linux distro and still get web access and it would keep their web history not on your computer where you could see. but on the flash stick or stored in Ram which will be blanked once the computer is restarted. Its a losing battle my friend and you would be wasting your money. Answered by adigitalslave - Tue Apr 15 01:52:34 2008 how to get proxy servers on my mobile internet?

Q. How does a proxy server work? Can my employer tell that I am using one and would their watchdog people be able to see the screens from a remote location? Would financial transactions with my bank account still be safe? Would passwords that I enter be private? Are there any risks to using one?

Your school or work filter can easily detect a proxy the very minute you try to use it and either block it on the fly or notify an admin to block it manually. There is no proxy that these new filter techniques cannot stop. At the end of the day all proxy's will eventually get blocked. As the filtering software gets more advanced they will get blocked faster and faster. There is also the question of the rules and laws you are breaking by trying to hack their security system. Finally even if you get a proxy to work for a short time you are inviting the proxy owner, many of whom are using the proxy for hacking purposes, to infect and or hijack your school or work network.
