CUNY Academic Commons

Yup, this seems fine with me. Not something I would support introducing into WP core, but fine for the Commons :)

Boone, I've committed the change on the server (commit 90e7f9a), but haven't pushed it to Github because I haven't pulled the latest changes to master branch on the server yet.

Wasn't sure what the release strategy was for 1.9.22, so thought I'd touch base with you before I did a git pull on the server.

Thanks, Ray. The commit looks good.

Since it's looking like the regularly scheduled 1.9.22 release will go out before the server migration, please do keep the 1.9.x and master branches so that they continue to work properly on the existing server. That said, your HTTP_X_FORWARDED_FOR check should mean that the commit does nothing at all on the existing server (unless someone's doing something nefarious), so I don't see any harm in putting it into the mainline branch.

Actually, I'm going to revert the commit and move the code to cac-env-config.php since this code is specific to the load balancer only.
