我现在的htaccess：
# Use PHP 5.3
AddType application/x-httpd-php53 .php
RewriteEngine On
RewriteBase /
#Removes access to the system folder by users.
#Additionally this will allow you to create a System.php controller,
#previously this would not have been possible.
#'system' can be replaced if you have renamed your system folder.
RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$ /index.php?/$1 [L]
#Checks to see if the user is attempting to access a valid file,
#such as an image or css document, if this isn't true it sends the
#request to index.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]
# If we don't have mod_rewrite installed, all 404's
# can be sent to index.php, and everything works as normal.

ErrorDocument 404 /index.php
我需要做一个规则，如果有人输入http://www.mypage.com/blog/blablatitle
它将他重定向到http://mypage.com/blog/blablatitle
头版和所有页面都一样。
我正在使用 CodeIgniter，但我认为这在处理 htaccess 时并不那么重要。
这个建议的解决方案在 CodeIgniter 中效果不佳：
RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^(.*)$ http://%1/$1 [R=301,L]
因为它在地址中添加了 index.php，例如：当我输入：
http://www.mypage.com/blog/blablatitle
它把我重定向到：
http://mypage.com/index.php?/blog/blablatitle
我需要：
http://mypage.com/blog/blablatitle
没有这个规则是可以的（没有索引，php）例如：http://mypage.com/blog/blablatitle
那么，如何改进此重定向规则 som index.php 的任何建议都不会出现在重定向链接中？
