Proxy
The Proxy page routes a zone's traffic to your origin and configures the core request/response settings that other features build on.
Hostnames are managed on their own page -- see Hostnames. To turn smoxy on or off for the whole zone, use the Enabled / Disabled toggle in the zone header; when the zone is disabled, smoxy passes traffic through as a plain reverse proxy without caching, optimization, or security.
Default Backend
Every zone needs a destination for traffic. On the Proxy page, you assign either a single origin server or a load balancer that distributes traffic across multiple origins.
- Navigate to your Zone in smoxy
- Open Proxy
- Select your origin or load balancer from the dropdown
This determines where smoxy sends requests by default. You can override this per-request using Conditional Rules.
INFO
Note: Origins and load balancers are created separately under Organization > Backends before they can be assigned to a zone.
Debug Headers
When enabled, smoxy adds debug information to HTTP response headers. This is useful for troubleshooting caching behavior, rule evaluation, and request routing.
Enable this during development or debugging, and disable it in production to avoid exposing internal details.
HTTP Headers
You can add custom HTTP headers that smoxy includes on every request or response for this zone.
Request Headers
Headers sent from smoxy to your origin server. Useful for passing additional context to your backend.
Format: One header per line as header-name = value
Response Headers
Headers sent from smoxy to the visitor's browser. Useful for security headers, CORS, or custom metadata.
Format: One header per line as header-name = value
Headers configured here apply to all requests on this zone. To set headers conditionally (e.g., only for specific paths or countries), use Conditional Rules.
Log Forwarding
Stream this zone's CDN access logs from the smoxy edge to your own log receiver in real time. You configure the receiver's hostname and port, the protocol and format to send in, and an optional token to authenticate. Only hostnames with the CDN enabled produce logs.
INFO
Note: Log forwarding is CDN only.
For the available protocols and formats and full setup details, see Log Forwarding.
For caching, security, image optimization and custom pages settings, see the respective feature documentation pages.
