pulling CI into another system

[eluser]Colin Williams[/eluser]
[quote author="phazei" date="1245317576"]It seems what I was attempting to work around it won't work. The app does a header redirect to the auth page with the return url as a get variable on the string, which won't work with my CI install. Something like /controller/model/?return_url=encoded url
CI just gives 404. I can't post the data.

So if this external app could somehow include what's needed to access the CI super global, that would be great...

Anyone know?[/quote]

The front controller, index.php. Still, this is a bad route to go.
