The company I work for has some paranoid security policies, some sites are blacklisted, some are whitelisted and that is ok. The problem is that 99.99% sites I visit are neither blacklisted, nor blacklisted. And when I enter such site (e.g. superuser.com or stackoverflow.com) first thing I see is a warning page, that says that this is a not white-list site, and I could proceed, but all my actions would be logged and violations prosecuted. And this page contains a "Continue" button that submits a confirmation to a corporate proxy and redirects you to the page you wanted.
This is too annoying, and I wrote a Greasemonkey script for clicking that button automatically. That solves the problem in my browser, but this is not enough.
Lots of software I use daily (as Java programmer) uses http-based services. E.g. IntelliJ IDEA or Eclipse download plugins using plain http. But the first thing they see when trying to download a plugin list is a corporate proxy warning, and of course this breaks the plugin repository interaction.
I have an idea to put some smart proxy between my software and corporate proxy, so that it would "click" the "Continue" button in background and pretend that this warning page did not appear. I.e. create a chain like (software) -> (smart proxy) -> (corporate proxy). But don't know any "smart proxy" software that can handle the problem.
