.HTACCESS URL格式重写

Is there a way for me to make a sort of universal URL like this:

/News?Today
/News?Archive

/News?703
/News?654
/News?308 (and so on)

Instead of:

/News?which=Today
/News?which=Archive

/News?which=703
/News?which=654
/News?which=308 (and so on)

A friend gave me a following suggestion, although he is not really sure this is the correct htaccess command:

RewriteRule /News?Today /News.php?which=Today

You can use this rule in your site root .htaccess:

DirectoryIndex Ena.php

RewriteEngine On
RewriteBase /

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+)$ Ena.php?open=$1 [L,QSA]

RewriteCond %{QUERY_STRING} ^([^=]+)$ 
RewriteRule ^/?$ Ena.php?open=%1 [L]

Not tested:

RewriteRule ^/News?(.*)$ /News.php?which=$1 [L,QSA]

The whole thing:

<IfModule mod_rewrite.c>
  RewriteEngine on
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule ^/News?(.*)$ /News.php?which=$1 [L,QSA]
</IfModule>
