Steven, We're currently looking at clustering our Spectra apps so I'm interested in the problems you have encountered, but don't quite understand what you are doing here. Why does refreshing the site model before adding a page help? From just quickly going through it in my head it would have to be more like this: Add new page on server 1 Call new page on server 1 (site model is updated in server scope) Tell all other servers to update site model before the page is called on them.
If your code is easily available, it'd be great to see it. Whilst we're on the subject of clustering... how do you manage to keep files (images etc.) in sync between the servers? Have you coded something in CF to automatically copy it across the cluster when a new file is uploaded.
