added following to improve page speed to .htaccess - .htaccess

Question

I input the following into my .htaccess file for www.localmarketingus.com
<ifModule mod_deflate.c>
<filesMatch "\.(css|js|x?html?|php|xml|html)$">
SetOutputFilter DEFLATE
</filesMatch>
</ifModule>
# BEGIN Turn ETags Off
<ifModule mod_headers.c>
Header unset Pragma
Header unset ETag
</ifModule>
FileETag None
# END Turn ETags Off
# BEGIN Compress text files
<ifModule mod_deflate.c>
<filesMatch "\.(css|js|x?html?|php|xml|html)$">
SetOutputFilter DEFLATE
</filesMatch>
</ifModule>
# END Compress text files

</filesMatch>
</ifModule>
# END Cache-Control Headers
# BEGIN Remove Last-Modified Header
<ifModule mod_headers.c>
Header unset Last-Modified
</ifModule>
# END Remove Last-Modified Header
However, when i ran GTMetrix and PageSpeed insights it still said that i need to leverage browser caching and vary: accept encoding??
Is there something I did wrong in the code??
Thanks,

Please add this:
#BEGIN Vary Accept Encoding
<IfModule mod_headers.c>
<FilesMatch "\.(js|css|xml|gz)$">
Header append Vary Accept-Encoding
</FilesMatch>
<FilesMatch "\.(ico|jpe?g|png|gif|swf)$">
Header set Cache-Control "public"
</FilesMatch>
<FilesMatch "\.(css)$">
Header set Cache-Control "public"
</FilesMatch>
<FilesMatch "\.(js)$">
Header set Cache-Control "private"
</FilesMatch>
<FilesMatch "\.(x?html?|php)$">
Header set Cache-Control "private, must-revalidate"
</FilesMatch>
</IfModule>
#END Vary Accept Encoding
Instead of:
#BEGIN Vary Accept Encoding
<IfModule mod_headers.c>
<FilesMatch "\.(js|css|xml|gz)$">
Header append Vary: Accept-Encoding
</FilesMatch>
</IfModule>
#END Vary Accept Encoding
You can check out my website on gtmetrix to see I scored 100 % on the "Specify a Vary: Accept-Encoding header" test. This is my website: http://www.fotoshooting.ro/
Good luck!
