Is it possible to write a web server running in a modern browser such as Chrome, Firefox, IE, Safari?

Question

In the Substratum Initial Coin Offering (ICO), the White Paper talks about solving problems of the current Internet, by allowing hosts to become web hosts.

Based on reading of the White Paper, the team looks like they're intending to write Javascript that runs on any modern browser (IE, Safari, Chrome, Firefox) on any platform (Windows, Linux, etc) to turn it into a web server.

As the White Paper is very general, I'm not sure if the team's Javascript is also having some form of access to uPnP technology that tells the nearest router to forward port 80 into the (supposed) web browser that's running on the web server.

Does anyone familiar with current web browsers know if browsers are capable of:

1. Providing access to uPnP that can tell routers to do port forwarding?
2. Running a web server using Javascript?

Thank you. (I'm familiar with general programming, just not capabilities of current web browsers. Please limit responses to capabilities of web browsers)

Answer 1

有一些JavaScript库可在浏览器中实现Web服务器，例如nohost。它基于filer JavaScript库，因此可以处理文件请求。

尽管我还没有看到关于此的演示，但是也许可以使用x86 emulator in JavaScript在浏览器中运行Linux服务器。
