HTTP Footer filter module for Nginx

Introduction

This is a module that is distributed with tengine which is a distribution of Nginx that is used by the e-commerce/auction site Taobao.com. This distribution contains some modules that are new on the Nginx scene. The ngx_http_footer_filter module is one of them.

This module implements a body filter that adds a given string to the page footer.

You might say that it provides a particular case of the http sub module in the sense that it adds something to the footer. You can do the same using the http sub module but using the footer filter should be faster since there's no string matching done on the request body.

Configuration example

location / {
    ## Using the $date_gmt variable from the SSI module (prints a
    ## UNIX timestamp).
    footer "<!-- $date_gmt -->";
    index index.html;
}

location ^~ /assets/css {
    ## Add CSS to the MIME types to be added a footer.
    footer_types text/css; 

    footer "/* host: $server_name - $date_local */";
}

Module directives

default: ``

context: http, server, location

It defines the string to be printed at the footer of the request body. This string can have variables embedded.

  2. Add the module to the build configuration by adding --add-module=/path/to/nginx-http-footer-filter.

  3. Build the nginx binary.

Tagging releases

I'm tagging each release in synch with the Tengine releases.

Other tengine modules on Github

  • http concat: allows to concatenate a given set of files and ship a single response from the server. It's particularly useful for aggregating CSS and Javascript files.

  • http slice: allows to serve a file by slices. A sort of reverse byte-range. Useful for serving large files while not hogging the network.

Original documentation

The original documentation in Chinese. Note that the examples given therein rely on non-standard Nginx variables that are not available on the official Nginx source but only on tengine.
