Special thanks go to all of our contributors and users!

Here’s the complete change log for this version (as compared to the

  • bugfix: the on-demand handler/filter registration mechanism did not
    work fully for config reload via the HUP signal.

  • bugfix: when setting a multi-value response header to a single
    value, the single value might be repeated on each old value.

  • feature: added some debugging outputs that can be enabled by the
    –with-debug option when building nginx or ngx_openresty.

  • bugfix: we should set header hash using ngx_hash_key_lc, not simply to

    other nginx output filter modules because we did not properly prepare
    the r->cache_control array at the same time.

  • bugfix: more_set_input_headers and more_clear_input_headers did not
    handle the Accept-Encoding request headers properly. thanks ѵ].

    memory reads because Nginx request header values must be null
    terminated. thanks Maxim D…

    entries could result in data loss. thanks Chris Dumoulin for the patch
    in github issue #6.

You may want to check out the HTML version of this change log here,
which should look better:

The ngx_headers_more module allows you to add, set, or clear any
output or input header that you specify. This is an enhanced version
of the standard headers module because it provides more utilities like
resetting or clearing “builtin headers” like Content-Type,
Content-Length, and Server.
