Depends on the site
Use google to search for a proxy. You can connect to sites usually blocked by using one of these proxy sites.
A hidden proxy means that you are invisible when using the internet. This means you can surpass firewalls and browser history information.
You must use a proxy, but recently local servers have taken to blocking sites using the phrase "Proxy" to block certain sites containing that word in the HTML or even jsut in the text within the site. Some proxy's are smart enough to not use the word "Proxy" in their site at all, other are too ignorant to see that we need these sites, and that they are spoiling it by using the word ! Anonymus_Lad

By using Proxies or Proxy Sites
The sole use of a proxy is not illegal however people use proxys to download/torrent illegal material and stay hidden, so it depends on what your using it for.
When one is referring to using a new proxy, one is usually referring to using a new online server or connection. Changing a proxy is usually done to access sites that have otherwise been blocked.
There are many proxy sites available. Once you select one that is most convenient for you, you will be able to bypass firewalls and access your Yahoo email by going to www.mail.yahoo.com.
The simplest way of achieving anonymous web surfing is by using a VPN or Proxy server to mask the individual's IP address. This way the details are not passed on to the connecting sites and the identity of the individual can remain hidden.
In order to view a website using a proxy, one first has to find a proxy. You can find one of these at Hidemyass. Once you find a proxy, you simply put the url that you want to visit into the proxy and then browse the website using the proxy.
Proxy servers can steal passwords. It is very simple to do and if you connect to an open proxy and enter passwords in it, it is easy for the server to extract your password and user names. Just because they can doesn't mean that they all do, however it is advisable not to enter personal details while using proxy sites to be on the safe side
