We just implemented a new feature into papaya CMS 5. It has now a domain handling. Just direct several domains to one papaya CMS installation. You can now set up how each domain is handled in the papaya Backend. Wildcards for subdomains are possible.
Here are the 5 options.
"default" - The domain handling does nothing, default options are used
"domain" - Redirects to the requested page on another domain
"page" - Redirects to a specified page on another domain
"language" - Redirects to a language if the main page is called without a language (e.g. / or /index.html to index.de.html)
"tree" - Limits the domain to a subtree of the pages
The last option "tree" allows you to have several websites with one papaya CMS installation. They will share the users and other data but are limited to one part of the pages.
