Answer:
Server Side Includes (SSI) is a simple mechanism that allow you to add dynamic elements into your HTML file without playing with complicated scripting languages such as PHP or Perl.

<IfModule mod_include.c>
AddType text/html .shtml
AddOutputFilter INCLUDES .shtml
</IfModule>
Restart Apache to take effect

How to check which mime types are supported by your Debian/Ubuntu
Answer:
The /etc/mime.types file is the system-wide rules which defined for mapping filename suffices to mime types. Your Apache on Debian based Linux will read this file and set the correct Content-type header for these files when serving to users.
# cat /etc/mime.typesTurn on expire headers in Apache
Answer:
By turning on the expire headers, browser will cache the files serving from Apache more aggressively, so as to reduce traffic loading to the Apache web server.
Steps:
Add the following lines to the Apache configuration (httpd.conf)
<IfModule mod_expires.c>
ExpiresActive On
# Cache all files for 2 weeks after access (A).
ExpiresDefault A1209600
# Do not cache dynamically generated pages.
ExpiresByType text/html A1
</IfModule>
Restart Apache to take effect
# apachectl -k graceful
Assume the module mod_expires is enabled
