A proxy web page also helps to hide whatever activity or content you may be looking at throughout a blocked web page. It is sort of like being invisible while looking at a blocked web page. You can find any number of proxies just by doing a simple search on the internet and choosing one that works for you.
When you visit a proxy website, you can just type in the website that you want to view, and it will load from there. Different types of proxy sites will either allow you to view the full site or a limited version of the site you need to view. If you are trying to unblock a site that you want to view videos on such as YouTube, you may have a bit of trouble finding the right proxy, but if you keep searching you will find what you need. Many government owned computer networks will most likely only allow you to view limited parts of pages you are viewing.
The best way to actually seek and find a decent proxy site is just by doing an internet search and browsing through various sites that offer proxy sites. You may have to play around with different sites to get past what is blocked, but once you do this, you will have no problem looking at the site that you need. Keep in mind that these sites may be blocked for a reason, and although you are virtually invisible while looking around, there are still ways that someone can track what you are doing, you are not completely invisible! Proxy sites are a great way to get past certain blocks and get to information that may be crucial to what you are doing.
