HTML minification and compression
0%
Description
To improve page loading, you can use Tidy for compressing HTML code (show source code of this example).
Yes the gain will be low, but this is a good start before to minify CSS and JavaScript files.
To further improve HTML compression, you can also gzip output.
Sorry, I don't know RUBY, but in PHP, you can gzip files with output buffering.

It relates to Rails 3 support which is implemented. Currently redmine serves quite good and small source.

Hi all, I have done a beautiful code to GZIP (because Thin+lighttpd can't do this) and minify (with Tidy) HTML page!
In the application_controller.rb:
require 'base64'
...
class ApplicationController < ActionController::Base
...
after_filter :tidy
def tidy
if response.body =~ /<html/i
response.header['Content-Encoding'] = 'gzip'
response.body = `php /.../myfile.php #{Base64.encode64(response.body).gsub(/\n/, 'ø')}`
end
end
And my PHP file:
error_reporting(E_ALL);
ini_set('display_errors', 1);
$html = base64_decode(str_replace('ø', "\n", $argv[1]));
$html = str_replace('></option>', '> </option>', $html);
$html = str_replace('></button>', '> </button>', $html);
$html = myTidyFunction($html); // my custom function that call Tidy
$html = str_replace('> </option>', '></option>', $html);
$html = str_replace('> </button>', '></button>', $html);
$html = str_replace('<meta charset="utf-8"/>', '<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>', $html);
$html = gzencode($html, 9, FORCE_GZIP);
echo $html;
Yeah, it's horrible!
But it works so very good.
