Introduction

URL Canonicalization , SEF, Error pages, SEO & Metadata, URL Redirection

The SEF Extended plugin extends the functionality of the standard System - SEF plugin without replacing it. The standard plugin must remain enabled.


Canonical

Generation and adjustment of Canonical URLs through the Joomla router, management of GET parameters, and exclusions for components and page types.

Redirects

The plugin performs 301 URL normalization. Domain redirects are based on the Site Domain value configured in Joomla's standard System - SEF plugin.
Redirects can be enabled independently for:
- protocol mismatch;
- www or non-www mismatch;
- domain mismatch;
- the presence of the .html suffix when Joomla suffixes are disabled;
- duplicate slashes in the URL.

404 Page

Displays the content of the selected menu item for a non-existent URL without changing the address in the browser and while preserving the HTTP 404 status. On multilingual sites, language associations of the selected menu item are used; if no suitable association exists, Joomla displays the standard error page. When switching languages, the original non-existent path is preserved and only the language prefix is changed.

System - SEF

The settings on this tab are directly linked to the parameters of the standard System - SEF plugin. They are saved in the standard plugin and are not duplicated in SEF Extended.

Плагин SEF Extended расширяет возможности стандартного плагина Система - SEF, не заменяя его. Стандартный плагин должен оставаться включённым.

Canonical

Формирование и корректировка Canonical через маршрутизатор Joomla, управление GET-параметрами и исключениями для компонентов и типов страниц.

Перенаправления

Плагин выполняет 301-нормализацию URL. Доменные перенаправления основываются на значении параметра Домен сайта стандартного плагина Система - SEF.
Можно отдельно включить перенаправление:
- при несовпадении протокола;
- при несовпадении варианта с www или без www;
- при несовпадении домена;
- при наличии суффикса .html, если суффиксы Joomla отключены;
- при наличии лишних косых черт в URL.

Страница 404

Отображение содержимого выбранного пункта меню для несуществующего URL без изменения адреса в браузере и с сохранением HTTP-статуса 404. На многоязычных сайтах используются языковые ассоциации выбранного пункта меню; если подходящая ассоциация отсутствует, Joomla показывает стандартную страницу ошибки. При переключении языка сохраняется исходный несуществующий путь, меняется только языковой префикс.

Система - SEF

Настройки на этой вкладке напрямую связаны с параметрами стандартного плагина Система - SEF. Они сохраняются в стандартном плагине и не дублируются в SEF Extended.
