I have built my static html on heroku. Here's the link: https://askheating.herokuapp.com/
Now when I am performing a test on GTMetrix, I have got a very bad score due to leverage browser caching.
This is my .htaccess script
AddType application/vnd.ms-fontobject .eot
AddType application/x-font-ttf .ttf
AddType application/x-font-opentype .otf
AddType application/x-font-woff .woff
AddType image/svg+xml .svg

ExpiresByType image/png "access plus 2592000 seconds"
ExpiresByType image/gif "access plus 2592000 seconds"
ExpiresByType application/x-shockwave-flash "access plus 2592000 seconds"
ExpiresByType text/css "access plus 604800 seconds"

Browser caching for .htaccess
The code below tells browsers what to cache and how long to "remember" it. It should be added to the top of your .htaccess file.
## EXPIRES CACHING ##
<IfModule mod_expires.c>
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 text/html "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 1 month"
</IfModule>
## EXPIRES CACHING ##
Save the .htaccess file and then refresh your webpage.
How to set different caching times for different file types
You can see in the above code that there are time periods like "1 year" or "1 month". These are associated with file types, as an example the above code states that a .jpg file (image) should be cached for a year.
If you want to change that and say you want your jpg images cached for a month you would simply replace "1 year" with "1 month". The values above are pretty optimized for most webpages and blogs.
Alternate caching method for .htaccess
The above method is called "Expires" and it works for most people using .htaccess so it takes care of caching for most people who are just getting started.
After you are more comfortable with caching, you may want to try Cache-Control, another method of caching which gives us more options.
It is also possible the expires method did not work for your server, in that case you may want to try to use Cache-Control.
Cache-Control
Cache-Control allows us to have a bit more control of our browser caching and many people find it easier to use once setup.
Example use in .htaccess
file:
# 1 Month for most static assets
<filesMatch ".(css|jpg|jpeg|png|gif|js|ico)$">
Header set Cache-Control "max-age=2592000, public"
</filesMatch>
The above code is setting a cache control header depending on file type.
