如何重定向.htaccess？ （多语言）

Question

我有一个多语言网站和。 Htaccess，显示所有页面。

我想重定向（使用代码301）询问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 ...

我对重定向的经验很少。你可以帮助我。如何准备Apache的htaccess文件以满足这个标准？怎么办？

提前致谢

删除lang=ru

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

删除home.html

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

删除start=0

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

交换start=##和lang=##

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