Hi, dear colleagues.
Is it possible prevent duplication content for increase Google ranging? I mean similar pages with different URL. For example, http:_//_site.com/vacancy and http:_//_site.com/vacancy/. Obviously, routes are absolutely similar.
Do you know how to implement automatically redirect from http:_//_site.com/vacancy to http:_//_site.com/vacancy/ with header 301?
P.S. Dear moderators, sorry for creating new topic, if such thread already exists.
For redirect you can use this snippet in .htaccess file:
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} !(.*)/$
RewriteRule ^(.*[^/])$ $1/ [L,R=301]
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} !(.*)/$
RewriteRule ^(.*[^/])$ $1/ [L,R=301]
Unfortunately, shuch snippet doesn’t works in Yii2, because Yii2 already use Rewrite Conditions in Input Point.
Давайте по-русски 
Странно, потому что у меня всё работает. Кладёте всё это в .htaccess файл, а сам файл кладёт не в корень приложения, а в директорию web.
Попробую ещё раз. Создам на русском форуме аналогичную тему. Мне казалось что надо где-то в базовом контроллере фильтры использовать.
Dear PendalF, thank you for your help. Now it works fine. There is the solution:
.htaccess file
AddDefaultCharset UTF-8
Options +FollowSymLinks
IndexIgnore */*
RewriteEngine on
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} !(.*)/$
RewriteRule ^(.*[^/])$ $1/ [L,R=301]
# if a directory or a file exists, use it directly
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# otherwise forward it to index.php
RewriteRule . index.php
And in my config:
/config/web.php file:
'urlManager' => [
'enablePrettyUrl' => true,
'showScriptName' => false,
'rules' => require(__DIR__ . '/routes.php'), // some my Router rules here
'suffix' => '/',
],
I hope, this solution will help somebody.
