Unit 1.3 Released§


I’m glad to announce a new release of NGINX Unit.

Changes with Unit 1.3                                            13 Jul 2018

    *) Change: UTF-8 characters are now allowed in request header field

    *) Feature: configuration of the request body size limit.

    *) Feature: configuration of various HTTP connection timeouts.

    *) Feature: Ruby module now automatically uses Bundler where possible.

    *) Feature: http.Flusher interface in Go module.

    *) Bugfix: various issues in HTTP connection errors handling.

    *) Bugfix: requests with body data might be handled incorrectly in PHP

    *) Bugfix: individual PHP configuration options specified via control
       API were reset to previous values after the first request in
       application process.

Here’s an example configuration with new parameters:

    "settings": {
        "http": {
            "header_read_timeout": 30,
            "body_read_timeout": 30,
            "send_timeout": 30,
            "idle_timeout": 180,
            "max_body_size": 8388608

    "listeners": {
        "": {
            "application": "mercurial"

    "applications": {
        "mercurial": {
            "type": "python 2",
            "module": "hgweb",
            "path": "/data/hg"

All timeouts values are specified in seconds. The max_body_size value is specified in bytes.

Please note that the parameters of the http object in this example are set to their default values. So, there’s no need to set them explicitly if you are happy with the values above.

Binary Linux packages and Docker images are available here:
