If you want to create a alias domain name and deliver the assets from that , please follow the steps mentioned here.

​@SrinivasCh4 you’ll find the code that builds the Dimensional Viewer URL in two places: the AEM viewer UI (server-side component + overlayable client JS) and the Scene7/Dynamic Media configuration that supplies the base host. Change options:
 

Quick locate steps

• Search the repo for the literal host "s7.scene7.com" (CRXDE / repo query). That will show the template/JS that builds the URL.
• Search for viewer code under these areas: /libs/dam/gui/components (viewer components) and /libs/dam/gui/content (asset preview UI).
• Search clientlibs for Dynamic Media/Scene7 (categories like dynamicmedia, scene7, dam.scene7) under /etc/clientlibs and /libs/clientlibs — the URL button is typically rendered with client‑side JS there.

Two places to change behavior

• Server/UI override: overlay the viewer component (copy from /libs to /apps) or override the clientlib JS that concatenates the host, and modify the output to use https://abc.com.
• Config approach (recommended): change the Scene7/Dynamic Media host mapping so AEM uses your custom host. Check OSGi config pages (/system/console/config) for Scene7/Dynamic Media settings (names like “Scene7” or “Dynamic Media”), or set up a CNAME / domain mapping in your Scene7/Dynamic Media account so the generated links use your domain (no code changes needed).

How to safely implement?

• Prefer domain mapping in Scene7 or update the OSGi Scene7 config so other features keep working.
• If you must change UI, overlay the specific viewer component or clientlib into /apps and update the JS/template. Keep backups and test in author/publish.

Note: Open an Adobe support case to request a custom alias for your Dynamic Media Classic account
