Some websites are blocked in my network, so I have to use a proxy outside my local network to access them. In order to maximize the speed, only blocked sites be accessed through proxy.
Currently, my browser(with a plugin named SwitchySharp) is doing the job of unlocking the blocked sites. However, it would be much better if a proxy server, which determines whether the requested sites are blocked or not, could do the work.
I don't know if I'm understood. The diagram below expresses the same idea.
Browser || Local Proxy: If the requested URL is in black list, then use a proxy outside the network to access it. If not, go for it directly.
I am in China, where a lot of websites are blocked. If there is such software, life can be much better: once the proxy is set, phones, tablets, laptops etc. can suddenly access all the world wide web has to offer.
I am asking this because if there isn't such thing, I will write one myself.
Thank you for reading this. Best regards.
