I would like to use the split segmentation extension to do a random 50/50 sampling of traffic and connect to a content modification extension. My issue is I only want to do the 50/50 split on a landing page where we are doing the content modification. People that do not access the landing page should not be included. Any ideas on how this can be accomplished? It seems the split segmentation extension when scoped to preload is global. All my website traffic will be split 50/50 vs just the web traffic accessing a specific landing page.
