How to Bypass Internet
Censor ship

There are a number of techniques to get past Internet filtering.

Using alternate domain names or URLs
One of the most common ways to censor a Web
site is to block access to its domain name, for
example, "news.bbc.co.uk". However, sites are
often accessible at other domain names, such as
"newsrss.bbc.co.uk". If one domain name is
blocked, try to find out if the content is available
at another domain.

You could also try to access special versions that
some Web sites create for smartphones. These
are often the same URL with the addition of "m"
or "mobile" at the beginning, for example:
http://m.google.com/mail (Gmail)
http://mobile.twitter.com
http://m.facebook.com or http://
touch.facebook.com
http://m.flickr.com
http://m.spiegel.de
http://m.hushmail.com

For instance http://twitter.com/ has been blocked
in Burma, whereas https://twitter.com/ has been
accessible.
