如何在.htaccess中重定向？ （多語言）

Question

我有一個多語種網站和。 Htaccess，它顯示所有頁面。

我想重定向（使用代碼301）詢問RewriteEngine。例如：

site.com?lang=ru => site.com (remove `lang=ru` - Russian only) 
site.com/news.html?lang=ru => site.com/news.html 

site.com/home.html => site.com (remove `home.html` - only on the main page) 
site.com/home.html?lang=ua => site.com/?lang=ua 

site.com/rev.html?lang=ua&start=0 => site.com/rev.html?lang=ua (If start = 0, then remove `start=0`) 
site.com/rev.html?lang=ua&start=27 => site.com/rev.html?start=27&lang=ua (should be conversely) 

and so on many ... 

我對重定向的經驗很少。你可以幫助我。如何準備Apache的htaccess文件以符合此標準？該怎麼辦？

在此先感謝

刪除lang=ru

RewriteCond %{QUERY_STRING} ^(.*)&?lang=ru(.*)$ 
RewriteRule ^(.*)$ /$1?%1%2 [L,R=301] 

卸下home.html

RewriteRule ^home.html$/[L,R=301] 

刪除start=0

RewriteCond %{QUERY_STRING} ^(.*)&?start=0(.*)$ 
RewriteRule ^(.*)$ /$1?%1%2 [L,R=301] 

交換start=##和lang=##

RewriteCond %{QUERY_STRING} ^(.*)lang=(.+)&start=([0-9]+)(.*)$ 
RewriteRule ^(.*)$ /$1?%1start=%3&lang=%2%4 [L,R=301]
