Anyterm

Anyterm提供了基于网页的终端模拟器，采用JavaScript和服务器端守护程序方式开发。

The daemon typically runs behind an HTTP proxy; it forks a shell and communicates with the script using XMLHTTP on port 80 or securely using SSL. This provides you with shell access to your machine from almost any Web browser, even when firewalls are in the way. The my.anyterm.org service provides access without the need to install anything on your servers.
