Javascript going through a Proxy

I am working on a project right now that requires some javascript for the proper functionality we are looking for. The problem we are running into is that the clients of this web-based app can only access the site through a proxy server (due to strict policies). This proxy server is stripping the javasc开发者_如何学编程ript from the page and we are unable to replicate the exact proxy setting to determine a solution. Has anyone ran into this problem before and found a solution?

If there's a fixed set of client machines, and you can go for Firefox only, you might be able to do something using a Firefox extension or a bookmarklet that fetches the Javascript some other way that the proxy doesn't recognize (e.g. as base64 encoded data). It would however certainly require a load of work, and you may have to program the extension yourself... Probably cheaper to buy a new Proxy.

Some of our customers had these problems and we told them to access our app via HTTPS and that cleared the issue since most proxy won't filter secured traffic.
