HTTP Server

http.server.api_enabled

Abbreviation

ht s a

Access

get/set

Description

Enable the HTTP Server RESTful API.

See Networking and Security, HTTP Server .

The API is enabled by default, so enabling the HTTP server with http.server.enabled also allows access to the API. To disable HTTP RESTful API calls when the HTTP server is running, set http.server.api_enabled to 0 .

Arguments

<1|true|on/0|false|off>

Default

1

http.server.auth_title

Abbreviation

ht s h

Access

get/set

Description

Configure the authentication header displayed when a user fails to enter a valid username or password. This sets the title of a web browser's authentication dialog.

Gecko OS sets the variable value in the WWW-Authenticate HTTP header:

WWW-Authenticate: Basic realm=<http.server.auth_title>

This variable should be used with http.server.username and http.server.password .

See Networking and Security, HTTP Server .

Arguments

title

http.server.cors_origin

Abbreviation

ht s c

Access

get/set

Description

Specifies origins for which the web browser same-origin policy is relaxed.

If <origin> is set to an empty string, then CORS is completely disabled.

For requests without credentials, a value of * acts as a wildcard, allowing any origin to access the resource.

If the value of http.server.cors_origin contains a # character, then the # character is replaced with the last 3 characters of the device's MAC address. This works in conjunction with using the # character in mdns.name .

See HTTP Server RESTful API, CORS .

Arguments

<origin>

Default

"" (empty string). To set the http.server.cors_origin variable to the empty string, supply an argument with two double quotes: ""

http.server.keep_alive_enabled

Abbreviation

ht s b

Access

get/set

Description

To avoid the overhead of opening and closing a new HTTP connection for each request, you can keep the HTTP connection open for a series of requests, or for a specified time.

If http.server.keep_alive_enabled is set to 1 and the HTTP request contains the header:

Connection: Keep-Alive

OR the Connection header is NOT in the request, then Gecko OS keeps the HTTP connection opened until it is manually closed by the client or device, or until no requests have been received for a period set by the http.server.keep_alive_timeout variable.

While the HTTP connection is open, the client can send additional REST API requests.

Note : If this feature is enabled AND the following header is added to the HTTP request, then the HTTP connection is closed after the HTTP response is returned.

Connection: Close
