We're about to launch development of a network of sites where the host provides content for potentially hundreds of domains. We want to cache content into text files to be read, vs hitting the database with each page view. We have several options. We can a) host each domain in an IP-less account and retrieve the cached content via either CFHTTP or CFFILE; b) create sub accounts (www.ourdomain.com/theirdomain) and pull in the content via CFINCLUDEs; or c) make them subdomains (http://theirdomain.ourdomain.com) and again, use CFHTTP or CFFILE to retrieve the content. Any recommendations on this would be greatly appreciated.
