Summary: Regex path matching in Sling Dynamic Include
Key: SLING-7621
URL: https://issues.apache.org/jira/browse/SLING-7621
Project: Sling
Issue Type: New Feature
Affects Versions: Dynamic Include 3.0.0
Reporter: Marek Krokosinski
In some cases one might want to include external content to a page. Example of
such external content are AEM Experience Fragments or Content Fragments, or Zen
Garden Snippets.
Sometimes such 3rd party content can be categorized into two categories:
* not included by SDI - content which should not be included separately (for
example when content requires page context)
* included by SDI - content which is static, so it can be cached because it
does not change often (header, footer), or because it changes once per week and
we don't want to invalidate whole cache.
Example content structure:
* /content/my-site/my-micro-site/en_gl/content/fragments/
* /content/my-site/my-micro-site/en_gl/content/fragments/cacheable-fragments
When content is specific to market (by market I mean for example British
market, German market etc.), and we would want to include that 3rd party
content using SDI, we would have to provide one Sling Dynamic Include
configuration per market.
As you may know, one site can have 100 or more markets, it means at least 100
configuration for such simple case (and usually, it's not the only one!).
Solution for this problem is to change the way, how SDI performs check on the
path.
Currently SDI checks if requested resource path starts from the configured
path.
Instead of simple check with startsWith, SDI should support regular
expressions, which are much more flexible.
In the given scenario we would have one simple configuration with path
configured to:
^/content/my-site/([a-zA-Z-_]+)/([a-z]\{2}_[a-z]\{2})/content/fragments/cacheable-fragments$
I have created pull requests which also provides some unit tests for
Configuration and ConfigurationWhiteboard classes.
