########################### HTACCESS optimization (TT's version) #################
##################################################################################
######################### ShortLink: https://git.io/v6ykm #######################
# NOTE 1: READ ALL NOTES & COMMENTS in this file, PLEASE!
# It's better if you paste this page fully in your HTACCESS.
# Suggestions are welcome! Mail me: tazotodua+github@gmail.com
# NOTE 2: In some low-quality hostings, these codes wont work in HTACCESS.
# NOTE 3: In some cases, if your hosting is limited, you can use different "CACHING" and
# "COMPRESSION" methods, rather than the my codes. For this, read the commented lines
# in "CACHING" and "COMPRESSION" blocks.
# NOTE 3: In case you dont have access to HTACCESS, see doing it with PHP: https://git.io/v6yfp
# NOTE 4: Remember, in HTACCESS, instead of ONE-LINE fileType commands, i.e.
# ExpiresByType image/jpg "access plus 3 months"
# You can use:
# <FilesMatch "\.(jpg|png)$">
# ExpiresDefault "access plus 3 months"
# </FilesMatch>
# NOTE 5: Most users wont ever need Manifest files. (Who needs them, read: http://goo.gl/3AFjt3 )
# NOTE 6: If you use this with Wordpress, it's better to insert this block before `WP` block.
# NOTE 7: Thanks to all contributors!

########### Turn off `Last-Modified` ##################
#Description: If you remove the `Last-Modified` and `ETag` header, you will totally eliminate
# `If-Modified-Since` and `If-None-Match` requests and their `304 Not Modified`
# responses, so a file will stay cached without checking for updates until the
# `Expires` header indicates new content is available!
# NOTE 1: Sometimes, your existing .htaccess may contains strange `Vary` commands (i.e. WordFence
# sets it to "Accept-Encoding, Cookie" --> https://goo.gl/9h2v52 ), so I re-set `Vary`.
# Otherwise images,js... CACHING doesnt work!
###########################################################
<ifModule mod_headers.c>
Header unset Last-Modified
Header set Vary "Accept-Encoding"

############## CACHING (`EXPIRE` method) ############
### Description: cache your files with `EXPIRES` method.
# NOTE 1: Caching explained: (a) https://goo.gl/kF3Nzb (b) https://goo.gl/USqPGl
# NOTE 2: If caching doesnt work, read the above paragraph "Turning off LAST-MODIFIED"
# NOTE 3: If your hosting cant use `EXPIRES`,try such `Cache-Control`: http://goo.gl/gME7cA
# NOTE 4: `EXPIRES` activates `mod_expires`, which automatically
# generates "Cache-Control:max-age=xxxx" header, so you dont need to add that.
# NOTE 5: Instead of "access plus 1 day" you can use A86400 (or whatever seconds you want ).
# NOTE 6: If you use FALCON/HTML caching, then remove the "text/html" line.

########### Turn off ETags (Entity tags) ##################
# Description: ETags are a mechanism to check for a newer version of a cached file. By removing
# the ETag header, you disable caches & browsers from being able to validate files,
# so they are forced to rely on your Cache-Control and Expires header.

</ifModule>
# the above "unset" is better, because `FileETag None` doesn't work always
