controller_admin_mailing_run_content

Serve the saved HTML copy of a mailing run for a specific language.

The admin_mailing_run_content dispatch maps /admin/mailings/run/:run_id/content/:language to this controller. The run_id identifies the mailing run and language selects its stored copy. The response contains the saved HTML directly; it does not render the current page again.

Access control

The controller requires the use mod_mailinglist permission and retrieves the copy through m_mailinglist_run:content/3. The model requires visibility of the mailed page and edit access to the mailing list. For the test mailing list, the authenticated sender can also access their own run. Missing copies and model access errors are reported as a missing resource.

Browser isolation

Responses carry cache prevention and no-index headers. A Content Security Policy sandbox blocks scripts and form submissions, restricts framing to the same site, and disallows base URLs. Images, styles, and fonts may load over HTTP or HTTPS; data images and inline styles are also allowed. This permits a preview of the saved email layout while keeping its HTML isolated from the administration UI.
