mod_rewrite to redirect/index.whatever to/is not working

我想将index.html_php_php5的所有请求重定向到 http://www.domain.co.uk/ 使用mod_rewrite,我已经用php逐字地从一本关于搜索引擎优化的书中复制了代码,然后添加到php5选项中,但它不起作用。这是我的完整.htaccess文件:

RewriteEngine On

#translate any .html ending into .php5
RewriteRule ^(.*)\.html$ /$1\.php5

RewriteCond %{THE_REQUEST} ^GET\ .*/index\.(php5|php|html)\HTTP
RewriteRule ^(.*)index\.(php5|php|html)$ /$1 [R=301,L]

#change / for ?
RewriteRule ^(.*)\.html/(.*)$ /$1\.html?$2

#strip .html from search res page
RewriteRule ^(.*)search/(.*)$ /$1search_results\.html/search=$2

#translate product details link from search res page
RewriteRule ^products/(.*)/(.*)/(.*)$ /product_details.php5?category=$1&title=$2&id=$3 [L]

#Translate products/psorisis/chamomile-skin-cream-P[x] to productview.php5?id=1
RewriteRule ^products/.*-P([0-9]+) /productview.php5?id=$1 [L]

我不知道那有什么问题,其余的都很好,很漂亮。有人有什么想法吗?
