I never really thought much of cross-scripting. I always knew there were some security involved when loading files from different domains but never really gave it much thought.

In my own dev environment everything worked fine yet deploying it to the hosting server has the exact opposite effect.

In this article I will try and capture some of my thoughts and experience as I went through the process of getting various sites to work with files hosted on different domains. This article is for Flash Player 8 (FP8) only.
