As solidot reported in October this year, the University of Massachusetts Amherst researchers have proposed a proxy server does not require access to the Internet system CacheBrowser, get bypassed DNS interference directly from content hosting one CDN provider's server shielding content. The advantage of this approach is that under load delay was much smaller than the Tor of class methods, but the drawback is only applicable to the use of CDN is blocked sites, and fortunately most large websites are blocked in China are using the CDN. CacheBrowser: CDN content caching Internet use But the Internet is evolving, more and more sites start using CDN hosted content, improve content access performance, reliability and security. IP masking traditional website content is valid, but for CDN hosted content, reviewers can not simply be masked, because this will bring huge collateral damage.

CacheBrowser now released a beta version of Chrome and Firefox plugin, source code released on Github. Before being shielded China's most popular Web site in 1000 to 80% can be used to bypass the plug-blockade.
