Caching with .htaccess and Apache will take your website and your web skills to the next level. This is some technical and advanced methods condensed to simple htaccess code examples for you. But you must take the time to understand caching with cache-control and other headers and HTTP options before you implement on a production server.
I found this very useful website with an interesting list of examples of htaccess configurations.
Caching with both mod_expires + mod_headers
# Turn on Expires and set default to 0 ExpiresActive On ExpiresDefault A0 # Set up caching on media files for 1 year (forever?) ExpiresDefault A29030400 Header append Cache-Control "public" # Set up caching on media files for 1 week ExpiresDefault A604800 Header append Cache-Control "public" # Set up 2 Hour caching on commonly updated files ExpiresDefault A7200 Header append Cache-Control "proxy-revalidate" # Force no caching for dynamic files ExpiresActive Off Header set Cache-Control "private, no-cache, no-store, proxy-revalidate, no-transform" Header set Pragma "no-cache"
Caching with mod_headers
# 1 YEAR Header set Cache-Control "max-age=29030400, public" # 1 WEEK Header set Cache-Control "max-age=604800, public" # 3 HOUR Header set Cache-Control "max-age=10800" # NEVER CACHE Header set Cache-Control "max-age=0, private, no-store, no-cache, must-revalidate"
Caching with mod_expires
ExpiresActive On ExpiresDefault A0 # 1 YEAR ExpiresDefault A29030400 # 1 WEEK ExpiresDefault A604800 # 3 HOUR ExpiresDefault A10800"

This goes in your root .htaccess file but if you have access to httpd.conf that is better.
This code uses the FilesMatch directive and the SetOutputFilter DEFLATE directive to only target files ending in .js or .css
