# Source of truth: cx-deeniyat-plus-backend-api/deeplinks/  (runbook: docs/2026-09-22_deep_links.md)
# Deployed to /srv/deeplinks/ and pulled in with ONE line as the FIRST line inside the
# admin.deenlearning.in <VirtualHost *:443>, above every other directive:
#
#     Include /srv/deeplinks/apache-deeplinks.conf
#
# Apache has no inline comments: keep every comment on its own line.

# The admin panel is a React SPA whose catch-all serves index.html for unknown paths.
# A vhost-level RewriteRule runs before Alias, so let our paths through first.
# "-" means no substitution: mod_rewrite declines and the Alias lines below map the request.
# END also stops any per-directory (.htaccess) rewrite from touching them afterwards.
