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_concat module is one of them.
The module is inspired by Apache's
modconcat. It follows the same
pattern for enabling the concatenation. It uses two ?, like this:
http://example.com/??style1.css,style2.css,foo/style3.css
If a third ? is present it's treated as version string. Like
this:
http://example.com/??style1.css,style2.css,foo/style3.css?v=102234
