  mod_gzip_item_include file .(html?|txt|css|js|php|pl)$
  mod_gzip_item_include handler ^cgi-script$
  mod_gzip_item_include mime ^text/.*
 mod_gzip_item_include mime ^application/x-javascript.*
 mod_gzip_item_exclude mime ^image/.*
 mod_gzip_item_exclude rspheader ^Content-Encoding:.*gzip.*

Use following code in your .htaccess file which is in your Magento root directory

<IfModule mod_headers.c>
     # YEAR
     <FilesMatch "\.(ico|gif|jpg|jpeg|png|flv|pdf)$">
          Header set Cache-Control "max-age=29030400"
     </FilesMatch>
     # WEEK
     <FilesMatch "\.(js|css|swf|woff)$">
         Header set Cache-Control "max-age=604800"
     </FilesMatch>
     # 45 MIN
     <FilesMatch "\.(html|htm|txt)$">
        Header set Cache-Control "max-age=86400"
     </FilesMatch>

     Header set Connection keep-alive

</IfModule>

<ifModule mod_gzip.c>
    mod_gzip_on Yes
    mod_gzip_dechunk Yes
    mod_gzip_item_include file \.(html?|txt|css|js|php|pl|asp|html)$
