The sling mappings provide the possibility of creating a multi-tenant setup. Multiple websites can be hosted, by providing Sling mappings that point to their specific content paths. These mappings consist of domains. I.e.:
* https://my-website-a.com/ -> /content/my-website-a * https://my-website-b.com/ -> /content/my-website-b There is, however, an issue with this setup, when using sling:vanityPath. Let’s say, we have the following structure: /content/my-website-a/info/openinghours@sling:vanityPath=’/openinghours’ /content/my-website-b/test@sling:vanityPath=’/test’ Now: When requesting https://my-website-a.com/openinghours , we see the content of /content/my-website-a/info/openinghours (sling:vanityPath) – Correct When requesting https://my-website-b.com/openinghours , we see the content of /content/my-website-b/info/openinghours – Incorrect! This content does not belong to this website! There seems to be support in Apache Sling for sling:vanityPath properties containing a full URL: https://github.com/apache/sling-org-apache-sling-resourceresolver/blob/4406b8fed0fedb48202fc6472fb552c36aa06e35/src/main/java/org/apache/sling/resourceresolver/impl/mapping/MapEntries.java#L1285 This could be used to make the above work. However, that would require us to store the protocol, domain & portnumber inside the sling:vanityPath property. That does not feel right. There is another option: We could try to use custom code to put the domains in front of sling:vanityPath property values, by using a ResourceDecorator. However, the ResourceDecorator in our custom bundle would not be started yet, when Sling is starting up and doing the inventory, because our bundle is dependent on the resourceresolver-bundle. This basically leaves us without any good “hook” into this entire process. If the sling:vanityPath property value contains a path (not a URL), https://github.com/apache/sling-org-apache-sling-resourceresolver/blob/4406b8fed0fedb48202fc6472fb552c36aa06e35/src/main/java/org/apache/sling/resourceresolver/impl/mapping/MapEntries.java#L1291 , the ANY_SCHEME_HOST constant is used, which has a value of “[^/]+/[^/]+” which basically means that any scheme and any host matches. Given the usecase I just described, it means that no matter where the sling:vanityPath properties are stored, as long as they match the request *path* only, they match. Then, the first one that is encountered (through the Iterator provided by getResolveMapsIterator) – Potentially the wrong one! When handling sling:vanityPath properties, there is not really any context of domains, Sling mappings, … Purely a vanity path. I think it could be possible to take the map entries into account, when handling the vanity paths. This should mean that the ANY_SCHEME_HOST-constant would not be used as part of the regex, but instead, we determine the host at a later part, by taking into account the Sling mappings. This would make the following cases possible: 1. Scope sling:vanityPath defined in a content path covered by a mapping, to only that mapping, causing them to not be able to be requested by other domains; 2. When having found multiple content paths defining the same sling:vanityPath, be able to actually select the right one (not tackling the issue where 2 or more of the same vanity paths are defined under the same content path); 3. Add a new Sling mapping (or remove / update an existing one) and the sling:vanityPath scoping work right away. So far, I’ve been experimenting a bit with the above and it seems most of it is possible already, just that MapEntry (which is where the ANY_SCHEME_HOST + vanity path value ends up as a regex) doesn’t have any knowledge of the Sling mappings. I was thinking of making a wrapper class, to store the vanity path without the scheme/host/port and allow it to dynamically select the right one based on the request coming in. I suppose it’s a good idea to be able to toggle this functionality, so that we don’t interfere with existing setups. And also, if a content path defines a sling:vanityPath that is not covered by a Sling Mapping – Should that sling:vanityPath be global then? Or not work at all? (I think it should be global, then.) Does anyone have any thoughts about this? 😊 If we’re able to decide how we want to approach this, I can put in some effort to make the changes.
