NAME

This is the nginx version of apache mod_concat but enhanced.

SYNOPSIS

location /foo/ {

# turn on concatenation # (default: off) concat on;

}

location /bar/ {

# turn on concatenation # (default: off) concat on;

# max concat file number allowed # (default: 10) # concat_max_files 10;

# only files in the same content types are allowed # (default on) # concat_unique on;

# content types allowed # (default: application/x-javascript, text/css) # concat_types text/html;

}

DESCRIPTION

The idea of combining multiple files together to speed up page rendering was first brought in perlbal, by David Davis. Then mod_concat was implemented by Ian Holsman at AOL. This technique is really simple but very useful, by specifing a set of files to load in one HTTP request.

This module basically works as what its apache cousin does. Additionally, it also support maximum concat file number setting and version string (the string after the third question mark will be treated as version string and ignored).
