Nginx Unit 1.27.0 Release: HTTPS Redirection, Configurable Filenames, and Platform Updates

Nginx Unit is a dynamic application server that can run alongside or independently of Nginx Plus and the open‑source Nginx, offering a RESTful JSON API for configuration changes without service interruption and designed for distributed applications.

Redirect HTTP requests to HTTPS

With TLS support and certificate management added to Unit, plain HTTP requests can now be redirected to a TLS‑enabled listener by setting the location value in a route action. The new $request_uri variable contains the original URI path and query, as shown in the example below:

{
    "listeners": {
        "*:443": {
            "tls": {
                "certificate": "example.com"
            },
            "pass": "routes"
        },
        "*:80": {
            "pass": "routes"
        }
    },
    "routes": [
        {
            "match": {
                "scheme": "http"
            },
            "action": {
                "return": 301,
                "location": "
{host}${request_uri}"
            }
        }
    ]
}

This configuration enables Unit to listen on both plain‑text and TLS ports, ensuring any request received on the plain‑text port is redirected to the TLS port.

Provide configurable filenames for pure‑path URIs

You can now specify an index in a route action to use a different default filename. The following example demonstrates serving default.html for URIs matching /cms/* while falling back to index.html for other paths:

"routes": [
    {
        "match": {
            "uri": "/cms/*"
        },
        "action": {
            "share": "/var/cms$uri",
            "index": "default.html"
        }
    },
    {
        "action": {
            "share": "/var/www$uri"
        }
    }
]

This configuration makes Unit serve default.html for pure‑path URIs under /cms/* and index.html for all other pure‑path URIs.
