Nginx

Another Nginx module i’ve tested today, nginx-nonewlines , basically, this module same as Evan Miller’s nginx mod_strip module , Evan Miller’s mod_strip module removes unnecessary whitespace (spaces, tabs, and newlines) from HTML documents and automatically leaves comments as well as <pre></pre> tags untouched. while using using nginx-nonewlines we should define¬† <!–SC_OFF–> and ¬†<!–SC_ON–> within the html code area that we’re intend to leaves them intact.

Here’s quick and dirty compiling nginx-nonewlines module

  • download the module
https://github.com/vedang/nginx-nonewlines/archives/master
  • add this line to ./configure step, compile and install
  # ./configure \
  ....
  ....
  --add-module=/path/to/vedang-nginx-nonewlines-ba02b59
  ....
  ....
  # make && make install

add folowwing directive to nginx’s config.

        server {
                gzip on;
                no_newlines on;
                listen       80;
                server_name  www.example.com;
                access_log  /var/log/nginx/nginx-test-access.log  main;

                location / {
                        root   /home/user/public_html;
                        index  index.html index.htm;

                }
		}

example source html code before adding no_newlines directive.

So far so good, but there is one bug here. if i turn off gzip to off, it throws error like this:

ERR_INVALID_CHUNKED_ENCODING

Well, that’s it for now.
