body: <p>I am using webpagetest to know my website  performance.I am found issue with Cache static content i.e. "Leverage browser caching of static assets: 88/100"</p>

  <p>How can i fix the issue ? </p>
  
  <p>My htaccess looks like:</p>
  
  <pre><code># compress text, html, javascript, css, xml:
  AddOutputFilterByType DEFLATE text/plain
  AddOutputFilterByType DEFLATE text/html
  AddOutputFilterByType DEFLATE text/xml
  AddOutputFilterByType DEFLATE text/css
  AddOutputFilterByType DEFLATE application/xml
  AddOutputFilterByType DEFLATE application/xhtml+xml
  AddOutputFilterByType DEFLATE application/rss+xml
  AddOutputFilterByType DEFLATE application/javascript
  AddOutputFilterByType DEFLATE application/x-javascript
  AddOutputFilterByType DEFLATE image/svg+xml
  AddOutputFilterByType DEFLATE image/png
  AddOutputFilterByType DEFLATE image/jpg
  AddOutputFilterByType DEFLATE image/gif
  
  # Or, compress certain file types by extension:
  &lt;ifModule mod_deflate.c&gt;
  &lt;filesMatch ".(js|css|html|htm|php|jpg|jpeg|woff|eot)$"&gt;
  SetOutputFilter DEFLATE
  &lt;/FilesMatch&gt;
  &lt;/ifModule&gt;
  
  # Direct Apache to send all HTML output to the mod_pagespeed output handler.
  AddOutputFilterByType MOD_PAGESPEED_OUTPUT_FILTER text/html
  </code></pre>
