url被重写而没有查询字符串

Question

任何类型为

的查询字符串的网址

www.example.com/categories/type1?var1=abc&var2=def

正在重写

而没有查询字符串部分。即

www.example.com/categories/type1

我正在使用ubuntu 12 LAMP堆栈中的apache2服务器。我的apache .conf文件有

<Directory /var/www/html>
Options Indexes FollowSymLinks MultiViews
DirectoryIndex index.php
AddType application/x-httpd .php
Order allow,deny
allow from all
</Directory>

我的.htaccess文件是

# 1 ---- Establish a custom 404 File not Found page ----    
ErrorDocument 404 /filenotfound.php

# 2 ---- Prevent directory file listing in all of your folders ----    
IndexIgnore *

RewriteEngine On
RewriteRule ^product1/([^/]*)$ /test_JSON.php?productId=$1 
RewriteRule ^api/follow/([^/]*)/([^/]*)$ /follow.php?Name=$1&user=$2 
RewriteRule ^category1/([^/]*)$ /$1.php [L]
RewriteRule ^ajax-product-collection/([^/]*)$ /ajax-product-collection.php/$1 
RewriteRule ^categories/(.*)$ /ajax-product-base1.php [L] 

有人可以告诉我导致这种行为的原因是什么吗？
