25 Useful Apache ‘.htaccess’ Tricks to Secure and Customize Websites

19. Redirecting entire website to https.

Following lines will help you transfer entire website to https:

RewriteEngine ON
RewriteCond %{HTTPS} !on
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}

The above lines enable the re-write engine and then check the value of HTTPS environment variable. If it is on then re-write the entire pages of the website to https.

20. A custom redirection example

For example, redirect url ‘http://www.abc.net?p=100&q=20 ‘ to ‘http://www.abc.net/10020pq’.

RewriteEngine ON
RewriteRule ^http://www.abc.net/([0-9]+)([0-9]+)pq$ ^http://www.abc.net?p=$1&q=$2

In above lines, $1 represents the first bracket and $2 represents the second bracket.

21. Renaming the htaccess file

For preventing the .htaccess file from the intruders and other people from viewing those files you can rename that file so that it is not accessed by client’s browser. The line that does this is:

AccessFileName	htac.cess

22. How to Prevent Image Hotlinking for your Website

Another problem that is major factor of large bandwidth consumption by the websites is the problem of hot links which are links to your websites by other websites for display of images mostly of your website which consumes your bandwidth. This problem is also called as ‘bandwidth theft’.

A common observation is when a site displays the image contained in some other site due to this hot-linking your site needs to be loaded and at the stake of your site’s bandwidth, the other site’s images are displayed. To prevent this for like: images such as: .gif, .jpeg etc. following lines of code would help:

RewriteEngine ON
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERERER} !^http://(www\.)?mydomain.com/.*$ [NC]
RewriteRule \.(gif|jpeg|png)$ - [F].

The above lines check if the HTTP_REFERER is not set to blank or not set to any of the links in your websites. If this is happening then all the images in your page are replaced by 403 forbidden.

23. How to Redirect Users to Maintenance Page.

In case your website is down for maintenance and you want to notify all your clients that need to access your websites about this then for such cases you can add following lines to your .htaccess websites that allow only admin access and replace the site pages having links to any .jpg, .css, .gif, .js etc.

RewriteCond %{REQUEST_URI} !^/admin/ [NC]
RewriteCond %{REQUEST_URI} !^((.*).css|(.*).js|(.*).png|(.*).jpg)	 [NC]
RewriteRule ^(.*)$ /ErrorDocs/Maintainence_Page.html

These lines check if the Requested URL contains any request for any admin page i.e. one starting with ‘/admin/’ or any request to ‘.png, .jpg, .js, .css’ pages and for any such requests it replaces that page to ‘ErrorDocs/Maintainence_Page.html’.

24. Mapping IP Address to Domain Name

Name servers are the servers that convert a specific IP Address to a domain name. This mapping can also be specified in the .htaccess files in the following manner.

For Mapping L.M.N.O address to a domain name www.hellovisit.com
RewriteCond %{HTTP_HOST} ^L\.M\.N\.O$ [NC]
RewriteRule ^(.*)$ http://www.hellovisit.com/$1 [L,R=301]

The above lines check if the host for any page is having the IP Address as: L.M.N.O and if so the page is mapped to the domain name http://www.hellovisit.com by the third line by permanent redirection.

25. FilesMatch Tag

Like <files> tag that is used to apply conditions to a single file, <FilesMatch> can be used to match to a group of files and apply some conditions to the group of files as below:

<FilesMatch “\.(png|jpg)$”>
Order Allow, Deny 
Deny from All

  1. Hi Sir,

    Someone hacked our website and always take it index.php file instead of a different php file.

    Also, the htaccess file gets created newly even we deleted it.

  2. Great htaccess tips, Thanks for sharing this helpful article. can you please give some suggestions about .htaccess security?

    • @Sajjad,

      Use the following directive to secure and restrict access to .htaccess file on the server.

      # Protect the htaccess file
      Order Allow,Deny
      Deny from all
  3. Hey Tosin,
    i don’t think about any ebook related htaccess because htaccess is part of logic which is every one can modified using his ability.
