Adobe Experience Manager (AEM)

The AEM platform in AEM 6 is based on Apache Jackrabbit Oak . Apache Jackrabbit Oak is an effort to implement a scalable and performant hierarchical content repository for use as the foundation of modern world-class web sites and other demanding content applications. It is the successor to Jackrabbit 2  and is used by AEM 6 as the default backend for its content repository, CRX. For more details ,visit  https://docs.adobe.com/docs/en/aem/6-2/deploy/platform.html

Cumulative Fix Pack Starting with AEM 6.1 Service Pack 2, Adobe has introduced a single delivery model for releasing fixes. Instead of releasing hot fixes for single issues, Adobe will release a Cumulative Fix Pack (CFP) every month (subject to passing quality checks), which is an aggregator content package for multiple fixes. CFPs do not include any improvements, but have the following advantages over single hotfix releases: Increased quality assurance Simplified installation (User installs a CFP as a single package that has no dependencies, except for the latest service pack) Cumulative in nature (for example, CFP3 contains fixes for CFP2 and CFP1) For more details  https://helpx.adobe.com/experience-manager/release-notes--aem-6-2-cumulative-fix-pack.html

Issue : In AEM 6.x, when we attempt to hit the static content, such as: /etc/designs/hello/1.html, it is treated like a binary download. Root cause:- This is an intended change made by Adobe engineering in AEM 6.2.  Even for 6.1, Adobe released a hotfix for it NPR-9381.  GRANITE-9550 - Extend content disposition filter protection to author. NPR-9381 - HF for GRANITE-9550 - Extend content disposition filter protection to author. This was introduced as part of Sling Security Fix . Solution:-  Open  OSGI configuration  org.apache.sling.security.impl.ContentDispositionFilter Add static file relative path (for example /etc/designs/hello/1.html ) in  Content Disposition Excluded Paths.
