Class SubdomainExtensionBasedMapper

Extends the functionality of an ExtensionBasedMapper to support identifiers containing subdomains. This is mostly only relevant in case you want to support multiple pods with subdomain identifiers in a single ResourceStore.

When converting to/from file paths, the subdomain is interpreted as a folder in the rootFilePath. The rest of the path is then interpreted relative to that folder. E.g. http://alice.test.com/foo results in the relative path /alice/foo.

In case there is no subdomain in the URL, the baseSubdomain parameter is used instead. E.g., if the baseSubdomain is "www", http://test.com/foo would result in the relative path /www/foo. This means that there is no identifier that maps to the rootFilePath itself. To prevent the possibility of 2 identifiers linking to the same file, identifiers containing the default subdomain are rejected. E.g., http://www.test.com/foo would result in a 403, even if http://test.com/foo exists.
