Just copy and paste the lines, with or without anymodification, from the below mentioned examples in your htaccess file and you should be all set.

There are several things that developers, site owners and webmasters can do by using .htaccess file. Let’s look at some of them:

• Prevent directory browsing
• Redirect visitors from one page or directory to another
• Password protection for directories
• Change the default index pageof a directory
• Prevent hot-linking of images from your website

Since .htaccess file allows us to make changes on a per-directory basis, the following are valid places to put the .htaccess file in:

/.htaccess [placing in root folder of the site]
/content/.htaccess [placing in content folder]
/content/html/images/.htaccess [in the images folder]
