some helpful .htaccess rules for speeding up buttcoin.org

## Keep-Alive, early in .htaccess
Header set Connection Keep-Alive
Header set Keep-Alive "timeout=7, max=25"

## About halfway through .htaccess, these preliminary rules for proper Internet Media types (MIME types)
<IfModule mod_mime.c>
 # Audio
 AddType audio/mp4 m4a f4a f4b
 AddType audio/ogg oga ogg
 # JavaScript
  # Normalize to standard type (it's sniffed in IE anyways):
  # http://tools.ietf.org/html/rfc4329#section-7.2
 AddType application/javascript            js jsonp es
 AddType application/json                  json map
 AddType application/x-ns-proxy-autoconfig pac
 # Video
 AddType video/mp4   mp4 m4v f4v f4p
 AddType video/ogg   ogv
 AddType video/webm  webm
 AddType video/x-flv flv
 # Web fonts
 AddType application/font-woff         woff
 AddType application/vnd.ms-fontobject eot
 # Browsers usually ignore the font MIME types and sniff the content,
 # however, Chrome shows a warning if other MIME types are used for the
 # following fonts.
 AddType application/x-font-ttf ttc ttf
 AddType font/opentype          otf
 # Make SVGZ fonts work on iPad:
 # https://twitter.com/FontSquirrel/status/14855840545
 AddType     image/svg+xml svg svgz
 AddEncoding gzip          svgz

 AddType text/x-vcard                        vcf
 AddType text/plain                          txt
 AddType text/css                            css
 AddType text/html                           html htm shtml shtm sht
 AddHandler server-parsed .html
 AddHandler server-parsed .htm
 AddHandler server-parsed .shtml
 AddHandler server-parsed .shtm
 AddHandler server-parsed .sht
</IfModule>

## Next, these rules for gzipping; comment out the <IfModule mod_filter.c> and following </IfModule> lines if your version of Apache doesn't have this module
<IfModule mod_deflate.c>
 # Force compression for mangled headers.
 # http://developer.yahoo.com/blogs/ydn/posts/2010/12/pushing-beyond-gzipping
 <IfModule mod_setenvif.c>
  <IfModule mod_headers.c>
   SetEnvIfNoCase ^(Accept-EncodXng|X-cept-Encoding|X{15}|~{15}|-{15})$ ^((gzip|deflate)\s*,?\s*)+|[X~-]{4,13}$ HAVE_Accept-Encoding
   RequestHeader append Accept-Encoding "gzip,deflate" env=HAVE_Accept-Encoding
  </IfModule>
 </IfModule>
 <Files ~ "^[^\.]+$">
  ForceType application/x-httpd-php
  SetOutputFilter DEFLATE
 </Files>
 # Compress all output labeled with one of the following MIME-types
 # (for Apache versions below 2.3.7, you don't need to enable `mod_filter`
 #  and can remove the `<IfModule mod_filter.c>` and `</IfModule>` lines
 #  as `AddOutputFilterByType` is still in the core directives).
 <FilesMatch "\.(js|es|jsonp?|map|pac|css|html?|xhtml?|xht|shtml?|sht|txt|appcache|manifest|php|xml|ico|bmp|otf|ttf|svg|woff)$">
  SetOutputFilter DEFLATE
 </FilesMatch>
 <IfModule mod_filter.c>
  AddOutputFilterByType DEFLATE application/atom+xml application/javascript application/json application/rdf+xml application/rss+xml application/vnd.ms-fontobject application/x-font-otf \
                                application/x-font-ttf application/x-javascript application/x-javascript-config application/x-ns-proxy-autoconfig application/x-web-app-manifest+json application/xhtml+xml \

 </IfModule>
 # Netscape 4.x has some problems...
 BrowserMatch ^Mozilla/4 gzip-only-text/html
 # Netscape 4.06-4.08 have some more problems
 BrowserMatch ^Mozilla/4\.0[678] no-gzip
 # MSIE masquerades as Netscape, but it is fine
 BrowserMatch \bMSIE !no-gzip !gzip-only-text/html
 # Don't compress images
 SetEnvIfNoCase Request_URI \.(?:gif|jpe?g|png)$ no-gzip dont-vary
 # Make sure proxies don't deliver the wrong content
 Header append Vary User-Agent env=!dont-vary
</IfModule>

## If you decide to make WebP versions of your site images available as part of your build process, here's how to serve them to browsers that support them
# Send WebP images to browsers that accept them
RewriteCond %{HTTP_USER_AGENT} !(Chrome\/[0-8]|Android\s[0-3])\.
RewriteCond %{HTTP_USER_AGENT} Chrome [OR]
RewriteCond %{HTTP_ACCEPT} \bimage/webp\b
RewriteCond %{REQUEST_URI} (.+\.)(bmp|gif|jpe?g|png)$ [NC]
RewriteCond %{DOCUMENT_ROOT}/$1webp -f
RewriteRule (.+\.)(bmp|gif|jpe?g|png)$ $1webp [T=image/webp,E=accept:1]

## Later on in .htaccess, some rules about language
AddDefaultCharset utf-8
DefaultLanguage en-US
AddLanguage en-US .html .htm .xhtml .xhtm .xht .shtml .shtm .sht .css .js .es .json .jsonp .map .pac wpad.dat .php

## Now some rules about cache-control and Expires headers
# BEGIN Expires headers
<IfModule mod_expires.c>
  ExpiresActive On
  ExpiresDefault "access plus 5 seconds"
  ExpiresByType image/x-icon "access plus 2592000 seconds"
  ExpiresByType image/jpeg "access plus 2592000 seconds"
  ExpiresByType image/png "access plus 2592000 seconds"
  ExpiresByType image/gif "access plus 2592000 seconds"
  ExpiresByType image/bmp "access plus 2592000 seconds"
  ExpiresByType image/webp "access plus 2592000 seconds"
  ExpiresByType application/pdf "access plus 2592000 seconds"
  ExpiresByType text/pdf "access plus 2592000 seconds"
  ExpiresByType application/vnd.pdf "access plus 2592000 seconds"
  ExpiresByType application/x-pdf "access plus 2592000 seconds"
  ExpiresByType application/x-shockwave-flash "access plus 2592000 seconds"
  ExpiresByType text/css "access plus 604800 seconds"
  ExpiresByType text/javascript "access plus 604800 seconds"
  ExpiresByType application/javascript "access plus 604800 seconds"
  ExpiresByType application/x-javascript "access plus 604800 seconds"
  ExpiresByType application/x-javascript-config "access plus 604800 seconds"
  ExpiresByType application/x-ns-proxy-autoconfig "access plus 604800 seconds"
  ExpiresByType text/html "access plus 600 seconds"
  ExpiresByType application/xhtml+xml "access plus 600 seconds"
  ExpiresByType text/plain "access plus 600 seconds"
</IfModule>
# END Expires headers
# BEGIN Cache-Control Headers
<IfModule mod_headers.c>
 <FilesMatch "\.(x?html?|shtml?|xhtm?|shtm?|php)$">
  Header set Cache-Control "private, must-revalidate"
 </FilesMatch>
 <FilesMatch "\.(ico|pdf|flv|jpe?g|png|gif|bmp|webp|css|css\.php|swf)$">
  Header set Cache-Control "public"
 </FilesMatch>
 <FilesMatch "\.(js|js\.php|es|jsonp?|map|pac)$">
  Header set Cache-Control "private"
 </FilesMatch>
</IfModule>
# END Cache-Control Headers

Now some rules about charsets
<IfModule mod_mime.c>
 AddCharset iso-8859-1 .pac wpad.dat
 AddCharset utf-8 .appcache .atom .css .js .es .json .jsonp .map .rss .vtt .webapp .xml
</IfModule>

## Finally, near the end, a rule about ETags (and a commented rule for turning ETags off)
#FileETag none
FileETag MTime Size
