A question about pseudo-static, suddenly forget a piece of code

A question about pseudo-static, suddenly forget a piece of code
I want to achieve such an effect: When the index.html exists, the access to the existence of the index.html file, does not exist, the pseudo-static to go through dynamic access, configured as follows:

 
  
 
   

 
   
Rewriteengine on
   

 
   
Rewritecond%{http_host} ^ (. *) www.aaa.com$ [OR]
   
Rewritecond%{http_host} ^ ([^www]*). aaa.com$
   
Rewritecond%{document_root}%{request_filename}!-f
   
Rewriterule ^ (. *) $ http://www.aaa.com.$1 [r,qsa,l]
   

 
   
Rewriterule ^/([a-za-z]+) \.html$/run.php?controller=$1&action=$1&default=1 [L]
   

 
   
ServerAdmin [email protected]
   
DocumentRoot "E:/www/home"
   
ServerName www.aaa.com
   
Errorlog "D:/appserv/log/index_error.log"
   
Customlog "D:/appserv/log/index_access.log" common
   
ErrorDocument 404 http://www.aaa.com/error_404.html
   
ErrorDocument 403 http://www.aaa.com/error_403.html
   

 
   
    
 
   
  
    
Options Indexes FollowSymLinks
    
DirectoryIndex index.html
    
AllowOverride None
    
Order Deny,allow
    
Allow from all
    
   
 
   
 
   


  
 

But the above configuration has a problem, when the index.html exist, the system also through pseudo-static access, help.
I am sure that the effect I am going to do is achievable, I have done this before, and then I lost my configuration, and I can't think of what I wrote wrong.
Help, thank you.

------Solution--------------------
#如果目录存在就直接访问目录不进行RewriteRule
Rewritecond%{request_filename}!-d

#如果文件存在, the file is accessed directly without the following rewriterule. (Do not overwrite if file or file does not exist)
Rewritecond%{request_filename}!-f
