基于Web的SSH应用程序是否实用？

Question

I'm trying to make a simple web app to do SSH commands. The UI would use ajax to handle the commands and return the response. I've been looking at the SSH2 functions of PHP to handle the SSH, but I can't figure out how to keep the connection open. I don't want to have to keep logging in for every new command, and it would be hard to keep track of what directory I was in. Is there a solution to this?

Due to its architecture PHP plugged into the web server can not have persistent handles to resources (such as files, sockets etc.). Consequently the answer is simple - you need some other server (not apache + PHP) to do the job. For example, IIS on Windows and Java servers let you have per-session storage and keep handles there.
