Domain Bridge

🔍 Overview

Domain Bridge is a lightweight redirect service used together with Tracking Domain Pipelines when proxy mode is enabled.

It performs a catch-all redirect:

• reads the current host (domain)
• looks up the target domain in a dedicated Redis instance (redis-domain-bridge)
• redirects to https://<target-domain>/<path>?<query>

If no mapping exists, it returns 500.

🧩 Redis mapping

Mappings are maintained by TrackingDomainPipeline when:

• with_proxy=True
• redirect_from is set
• active_domain is set
• is_active=True

In this case Link Switcher keeps a key-value mapping:

• key: redirect_from
• value: active_domain

The mapping is synced on pipeline save/delete.

⚙️ Behavior

• Always redirects to HTTPS.
• Preserves the original path and query string.
• Intended to be used as a separate entrypoint/URLconf (apps/domain_bridge/urls_redirect.py).

🛠️ Configuration

Domain Bridge uses a dedicated Redis instance:

• REDIS_DOMAIN_BRIDGE_HOST
• REDIS_DOMAIN_BRIDGE_PORT
• REDIS_DOMAIN_BRIDGE_DB

🩺 Health check

Domain Bridge exposes a dedicated health-check endpoint:

• /ht/<HEALTH_CHECK_SECURITY_KEY>/

The check validates connectivity to redis-domain-bridge.
