By customizing your error code pages, you will also be increasing the overall security of your server. Most servers use the same error codes that the server came with. This has led to people attempting to use Google to search for all the web pages that have a certain string of text in them in order to obtain a list of all the web servers running a certain version of software that has an exploit. Customizing error codes will help you stay away from these kinds of Internet searches and the exploits that the results target.

Password protection is one of the most commonly used features of .htaccess files. It is also a bit more difficult to set up than customized error codes, but it s far more versatile in its ability to control access to directories. First, create a new file called .htpasswd in the directory you want protected. Create and save this file in the same fashion as the .htaccess file. The .htpasswd file will contain usernames and their passwords. Now, enter the username and password information into it. The information is stored in the following manner: username:password username:password charles:mypassword In the previous example, the username, a colon, and a password are on individual lines and do not have any spaces at the end of each line.
Note The username fields remain in English, but the password fields need to be encrypted to keep them
secure. Many scripts are available online that encrypt passwords for you. A quick Internet search should find plenty of scripts. We prefer to use sites such as http://www.coderz.com to find code for these types of tasks.
Once the file is created and the usernames and passwords are entered, the file must be uploaded in ASCII format and stored above your WWW or public_html folder, that is, in your online root (home) folder. (You might have to ask your host provider exactly what path this is and where it is located.) Remember that the .htaccess file will affect the current directory only, plus any subdirectories connected to it. Be sure you are placing this in the right folder. Sometimes one directory section needs protection; other times, the whole site needs it. Next, you will need to add coding to the .htaccess file for the directory you want to protect: AuthUserFile /home/pathto/.htpasswd AuthType Basic AuthName "THE Secret PlaceREALM"
<LIMIT GET POST> require valid-user </LIMIT>

Let s explore what this code means, starting with the first line: AuthUserFile /home/pathto/.htpasswd allows the browser to find the right path to your .htpasswd file. The rest of the command after AuthUserFile specifies the path leading to the actual file name. AuthType Basic defines the type of encryption to be used. There are multiple methods of encryption, but Basic is the most commonly used. However, it shouldn t be used for any systems that host high-traffic or high-security environments. AuthName "Private Realm" defines how your protected directory is referred to in the pop-up message box when the visitor hits the protected area. This name is yours to choose. The users see only what is inside the quotes. This last part of the script tells the browser to check credentials that the visitor enters into the box against the information in your .htpasswd file: <LIMIT GET POST> require valid-user </LIMIT> When visitors try to access a page within a protected directory, they will get a dialog box asking for a username and password. If they enter bad information, they will be directed to an error page. If you would rather password-protect a specific file than a folder, you can use this file name in your .htaccess file, where the AuthUserFile variable defines the specific file or web page for which you want to control access: <files "filename.cgi"> AuthUserFile /home/pathto/.htpasswd AuthType Basic AuthName "Secret Place" require valid-user </files> Finally, you can and should protect your .htaccess file from being viewed by visitors using this code in the .htaccess file: <files ".htaccess"> order allow,deny deny from all </files>
