Hi there, I've developed a few zope applications for various clients now, and I'm looking at offering them hosting facilities. I'm trying to get a handle on the best way to run multiple 'sites' from one computer. What I'd like to do is run x.com, y.com, and z.com from 3 different data.fs files. My research over the last couple of hours points me to running a master data.fs, and using the siteaccess/siteroot products to redirect incoming requests to folders which are actually external storages. Does anyone else use this approach? If so, and there any tricks or traps I should watch out for? If I wanted to replace the z.com data.fs with a new one, would I have to shut down the master.fs, or just copy the old one over the new one? Does anyone run more than one instance of zope at once to serve multiple data.fs's? What are the other approaches in use? Suggestions? Cheers! Tim.
