It works for phpBB 3.1.x, not just phpBB 3.1.6. For a national forum or global forum, it is a must to have a CDN support.
The way I used is not a formal extension or plugin. It is a hack, actually a dirty hack. If you have no experience for it, you can close this page now.
Now, let’s start.
- Backup everything of your phpBB, include files and database.\
- URL path example.
Forum url is http://www.myforum.com/
CDN url is http://myforum.kxcdn.com/ - Open /includes/functions.php
add following in line 5112// Add CDN path $cdn_cache = '//myforum.kxcdn.com/';
Find following around Line 5216
'T_ASSETS_PATH' => "{$web_path}assets", 'T_THEME_PATH' => "{$web_path}styles/" . rawurlencode($user->style['style_path']) . '/theme', 'T_TEMPLATE_PATH' => "{$web_path}styles/" . rawurlencode($user->style['style_path']) . '/template',Replace by
'T_ASSETS_PATH' => $cdn_cache."assets", 'T_THEME_PATH' => $cdn_cache."styles/" . rawurlencode($user->style['style_path']) . '/theme', 'T_TEMPLATE_PATH' => $cdn_cache."styles/" . rawurlencode($user->style['style_path']) . '/template',
Find following around Line 5230
'T_STYLESHEET_LINK' => "{$web_path}styles/" . rawurlencode($user->style['style_path']) . '/theme/stylesheet.css?assets_version=' . $config['assets_version'], 'T_STYLESHEET_LANG_LINK' => "{$web_path}styles/" . rawurlencode($user->style['style_path']) . '/theme/' . $user->lang_name . '/stylesheet.css?assets_version=' . $config['assets_version'],Replace by
'T_STYLESHEET_LINK' => $cdn_cache."styles/" . rawurlencode($user->style['style_path']) . '/theme/stylesheet.css?assets_version=' . $config['assets_version'], 'T_STYLESHEET_LANG_LINK' => $cdn_cache."styles/" . rawurlencode($user->style['style_path']) . '/theme/' . $user->lang_name . '/stylesheet.css?assets_version=' . $config['assets_version'],
Save and overwrite the original file.
- Open /includes/functions_content.php
Find following around Line 902return preg_replace('#<!\-\- s(.*?) \-\-><img src="\{SMILIES_PATH\}\/(.*?) \/><!\-\- s\1 \-\->#', '<img class="smilies" src="' . $root_path . $config['smilies_path'] . '/\2 />', $text);Replace by
return preg_replace('#<!\-\- s(.*?) \-\-><img src="\{SMILIES_PATH\}\/(.*?) \/><!\-\- s\1 \-\->#', '<img class="smilies" src="' .'//forum.kxcdn.com/forum/'.$root_path. $config['smilies_path'] . '/\2 />', $text);Save and overwrite the old file.
- Then purge cache in the ACP.
Look at the waterfall chat after this hack.
The CDN service provider is KEYCDN. You can apply through this link.
