How to protect your web pages from non cuhk access

Dear IE Students,

If you want to protect your web pages from non cuhk access, please follow these steps:

1. mkdir a directory under your ~/public_html
2. In this directory create a file ".htaccess" file with the following lines
   

   
       <Limit GET>
       order deny,allow
       deny from all
       allow from .ie.cuhk.edu.hk 
       </Limit>
   
    

3. put the HTML documents that you want to protect under this directory
4. now these HTML documents can only be accessed by ie.cuhk.edu.hk hosts
