Static titles plugin for YOURLS provide two options to avoid the network traffic when retrieving URL titles. You can either disable this feature entirely or provide a list of title and URLs as a cache mechanism.
Open configuration file config.php and append the following:
/*
** Personal settings would go after here.
*/
define('STATIC_TITLES_SKIP', false);
$static_titles = array(
'http://google.com' => 'Google',
);Setting STATIC_TITLES_SKIP to true will force all titles to Untitled. This will save you from bandwidth and minimize the time needed to create the short url entry.
The static_titles entry is only applicable if STATIC_TITLES_SKIP is set to false. You can define a list of URLs and title to be used by the plugin, overwriting the website title.
