我要重定向 http://olddomain.com 以 HTTP：/ /newdomain.com 为我所有的urls..keeping页面上相同的新领域。 我的意思是说的网址，如以下

I want to redirect http://olddomain.com to http://newdomain.com for my all urls..keeping the page on new domain same. What i mean to say is URLs such as below

http://olddomain.com/home/category/page.html
http://olddomain.com/home/mybook/page2.html
http://olddomain.com/login

should be 301 redirect to the new newdomain but same pages, like below

http://newdomain.com/home/category/page.html
http://newdomain.com/home/mybook/page2.html
http://newdomain.com/login

这是我在我的.htaccess目前

this is what i have in my .htaccess currently

RewriteEngine on
RewriteCond $1 !^(index.php|img|public|robots.txt) [NC]
RewriteRule ^(.*)$ /index.php?/$1 [L]

请帮我做这件事干净，exlpain事情的细节，因为我是新本。

Please help me to do this cleanly and exlpain things in details since i am new in this.

也没有人知道多少时间，搜索引擎可能需要从我olddomain重定向的引用搬走？我的意思是在搜索查询中的老域名的URL应该用新域的网址被替换，...​​，N旧域应该从搜索引擎消失。

also does someone know how much time search engines might take to move away from the references of my olddomain? i mean the old-domain urls in search queries should be replaced by new-domain urls... n old domain should go away from search engines.

推荐答案

添加以下code处的.htaccess的开始 -

Add following code at the beginning of .htaccess -

    RewriteEngine On

    # Redirect Entire Site to New Domain
    RewriteCond %{HTTP_HOST} ^olddomain.com$ [OR]
    RewriteCond %{HTTP_HOST} ^another.olddomain.com$ [NC]
    RewriteRule ^(.*)$ http://newdomain.com/$1 [R=301,L]
