Hide File Extensions In Browsers Using .htaccess


Many of us programmers want to hide the file extension of server files such as .php, .jsp, .py etc….

You can easily hide these extensions with the help of a .htaccess file. This feature is only available to Apache servers.
Create a file named .htaccess if your root directory of site doesn’t have one.
Add these lines to the .htaccess file :
<span style="background-color: white; font-family: inherit;"><span class="kw1" style="border: 0px; color: #2060a0; line-height: 18.200000762939453px; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline; white-space: nowrap;">RewriteEngine</span><span style="line-height: 18.200000762939453px; white-space: nowrap;"> </span><span class="kw2" style="border: 0px; color: #2060a0; line-height: 18.200000762939453px; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline; white-space: nowrap;">on</span></span>
<span style="background-color: white; font-family: inherit;"><span class="kw1" style="border: 0px; color: #2060a0; line-height: 18.200000762939453px; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline; white-space: nowrap;">RewriteCond</span><span style="line-height: 18.200000762939453px; white-space: nowrap;"> %{REQUEST_FILENAME} !-d</span></span>
<span style="background-color: white; font-family: inherit;"><span class="kw1" style="border: 0px; color: #2060a0; line-height: 18.200000762939453px; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline; white-space: nowrap;">RewriteCond</span><span style="line-height: 18.200000762939453px; white-space: nowrap;"> %{REQUEST_FILENAME}.php -f</span></span>
<span style="background-color: white; font-family: inherit;"><span class="kw1" style="border: 0px; color: #2060a0; line-height: 18.200000762939453px; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline; white-space: nowrap;">RewriteRule</span><span style="line-height: 18.200000762939453px; white-space: nowrap;"> .* $0.php</span></span>
The above lines wll hide the PHP extension. If you want to hide the HTML and other extension too add these line after 
<span class="kw1" style="border: 0px; color: #2060a0; line-height: 18.200000762939453px; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline; white-space: nowrap;">RewriteCond</span><span style="line-height: 18.200000762939453px; white-space: nowrap;"> %{REQUEST_FILENAME}.php -f</span>
as you want. You can also replace it if you don’t want php extensions to hide.

<span class="kw1" style="border: 0px; color: #2060a0; line-height: 18.200000762939453px; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline; white-space: nowrap;">RewriteCond</span><span style="line-height: 18.200000762939453px; white-space: nowrap;"> %{REQUEST_FILENAME}.py -f</span>

JS

<span class="kw1" style="border: 0px; color: #2060a0; line-height: 18.200000762939453px; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline; white-space: nowrap;">RewriteCond</span><span style="line-height: 18.200000762939453px; white-space: nowrap;"> %{REQUEST_FILENAME}.js -f</span>
You really should go into each page and delete the extensions, but I believe you can redirect them by adding another rule :
<span style="color: #2060a0;">RewriteRule </span>(.*).<span style="color: red;">html</span> $1 [R=301,NC]
The above rule will redirect all .html pages to non .html extension page.
Replace the red highlighted text with any extension you want to redirect.
