Leverage browser caching
16,479
Solution 1
Caching is controlled via a variety of HTTP headers. You should read Mark Nottingham's Caching Tutorial for Web Authors and Webmasters. You can set HTTP headers for documents outputted from PHP using the header function.
Solution 2
You can do something like this in your .htaccess.
## EXPIRES CACHING ##
<IfModule mod_expires>
ExpiresActive On
ExpiresByType image/jpg "access 1 year"
ExpiresByType image/jpeg "access 1 year"
ExpiresByType image/gif "access 1 year"
ExpiresByType image/png "access 1 year"
ExpiresByType text/css "access 1 month"
ExpiresByType application/pdf "access 1 month"
ExpiresByType text/x-javascript "access 1 month"
ExpiresByType application/x-shockwave-flash "access 1 month"
ExpiresByType image/x-icon "access 1 year"
ExpiresDefault "access 2 days"
</IfModule>

According to: http://code.google.com/speed/page-speed/docs/caching.html#LeverageBrowserCaching I should be using browser caching. However, I don't know how.
Do I simply add certain tags into the html section? Or is thing something I need to send via to server to the client? something to do with php headers?

Nisse Engström almost 8 years@Rikesh: Is the code above quoted from somewhere or is it your own code? I originally though it was copy/pasted from the same place as Ashraf Malik's answer, but I see now that yours was posted years earlier. Did Ashraf plagiarise your code?
