in a jailed environement?

Thanks.

Define that.

I mean a standalone implementation of javascript which would be made to operate within a fixed directory, period.

No possibility to get out to create temporary files, symbolic links to files outside this directory; no possibility for example, to set cookies outside either.

No possibility to get called from within a browser which could afterwards create/manipulate files outside of that environment.

OK. Maybe (not default) could be configured to do so... ;)

mozilla.org offers two open source version of a JavaScript interpreter.
SpiderMonkey is the code-name for the Mozilla's C implementation of
JavaScript. See:

Rhino is an open-source implementation of JavaScript written entirely in
Java. See:

I knew that.

But that means go through the source and maybe modify the code so as to achieve
what I want.

Just wanted to know if anybody had done it so far.

Wouldn't be surprising in regard of the numerous exploits using javascript.
