htaccess file

This is the base .htaccess configuration. Please take a look for the default variables (SFC_ROOT, SFC_GZIP) and read the comments carefully.

### Begin: Static File Cache (preparation) ####

# Document root configuration
RewriteRule .* - [E=SFC_ROOT:%{DOCUMENT_ROOT}]
# RewriteRule .* - [E=SFC_ROOT:%{DOCUMENT_ROOT}/t3site] # Example if your installation is installed in a directory

# Cleanup URI
RewriteCond %{REQUEST_URI} ^.*$
RewriteRule .* - [E=SFC_URI:/%{REQUEST_URI}]
RewriteCond %{REQUEST_URI} ^/.*$
RewriteRule .* - [E=SFC_URI:%{REQUEST_URI}]
RewriteCond %{REQUEST_URI} ^/?$
RewriteRule .* - [E=SFC_URI:/]

# Cleanup HOST
RewriteCond %{HTTP_HOST} ^([^:]+)(:[0-9]+)?$
RewriteRule .* - [E=SFC_HOST:%1]

# Get scheme
RewriteCond %{SERVER_PORT} ^443$ [OR]
RewriteCond %{HTTP:X-Forwarded-Proto} https
RewriteRule .* - [E=SFC_PROTOCOL:https]
RewriteCond %{SERVER_PORT} !^443$
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteRule .* - [E=SFC_PROTOCOL:http]

# Get port (not used at the moment)
RewriteRule .* - [E=SFC_PORT:80]
RewriteCond %{SERVER_PORT} ^[0-9]*$ [OR]
RewriteRule .* - [E=SFC_PORT:%{SERVER_PORT}]

# Check if the requested file exists in the cache, otherwise default to index.html that
# set in an environment variable that is used later on
RewriteCond %{ENV:SFC_ROOT}/typo3temp/tx_staticfilecache/%{ENV:SFC_PROTOCOL}/%{ENV:SFC_HOST}%{ENV:SFC_URI} !-f
RewriteRule .* - [E=SFC_FILE:index.html]

# Note: (Please check the realurl configuration related to "appendMissingSlash". Perhaps you need an additional "/" in the rule above)
# RewriteRule .* - [E=SFC_FILE:/index.html]

# Set gzip extension into an environment variable if the visitors browser can handle gzipped content and the gz-file exists
RewriteRule .* - [E=SFC_GZIP:]
RewriteCond %{HTTP:Accept-Encoding} gzip [NC]
RewriteRule .* - [E=SFC_GZIP:.gz]
RewriteCond %{ENV:SFC_ROOT}/typo3temp/tx_staticfilecache/%{ENV:SFC_PROTOCOL}/%{ENV:SFC_HOST}%{ENV:SFC_URI}%{ENV:SFC_FILE}%{ENV:SFC_GZIP} !-f
RewriteRule .* - [E=SFC_GZIP:]

# Note: We cannot check realurl "appendMissingSlash" or other BE related settings here - in front of the delivery.
# Perhaps you have to check the "SFC_FILE" value and set it to your related configution e.g. "index.html" (without leading slash).

### Begin: Static File Cache (main) ####

# We only redirect URI's without query strings
RewriteCond %{QUERY_STRING} ^$

# It only makes sense to do the other checks if a static file actually exists.
RewriteCond %{ENV:SFC_ROOT}/typo3temp/tx_staticfilecache/%{ENV:SFC_PROTOCOL}/%{ENV:SFC_HOST}%{ENV:SFC_URI}%{ENV:SFC_FILE}%{ENV:SFC_GZIP} -f

# NO frontend or backend user is logged in. Logged in users may see different
# information than anonymous users. But the anonymous version is cached. So
# don't show the anonymous version to logged in users.
RewriteCond %{HTTP_COOKIE} !staticfilecache [NC]

# Uncomment the following line if you use MnoGoSearch
#RewriteCond %{HTTP:X-TYPO3-mnogosearch} ^$

# We only redirect GET requests

# Rewrite the request to the static file.
RewriteRule .* %{ENV:SFC_ROOT}/typo3temp/tx_staticfilecache/%{ENV:SFC_PROTOCOL}/%{ENV:SFC_HOST}%{ENV:SFC_URI}%{ENV:SFC_FILE}%{ENV:SFC_GZIP} [L]

# Do not allow direct call the cache entries
RewriteCond %{ENV:SFC_URI} ^/typo3temp/tx_staticfilecache/.*
RewriteRule .* - [F,L]

### Begin: Static File Cache (options) ####

# Set proper content type and encoding for gzipped html.
<FilesMatch "\.gz">
   <IfModule mod_headers.c>
      Header set Content-Encoding gzip

# if there are same problems with ForceType, please try the AddType alternative
# Set proper content type gzipped html
<FilesMatch "\.html\.gz">
   ForceType text/html
   # AddType "text/html" .gz
<FilesMatch "\.xml\.gz">
   ForceType text/xml
   # AddType "text/xml" .gz
<FilesMatch "\.rss\.gz">
   ForceType text/xml
   # AddType "text/xml" .gz

### End: Static File Cache ###

If you use the oldschool .htaccess rewrite rules that come with the TYPO3 dummy, then the relevant static file cache configuration should be inserted in the .htaccess file just before these lines:

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-l
RewriteRule .* index.php [L]

If the TYPO3 Installation isn´t in your root directory (say your site lives in, then you have to add the '/t3site' part to the configuration snippet. It must be placed right after %{DOCUMENT_ROOT}. Here is the line of the ruleset to illustrate:

RewriteRule .* - [E=SFC_ROOT:%{DOCUMENT_ROOT}/t3site]

You are of course free to make the rules as complex as you like.

There might be some files you never want to pull from cache even if they are indexed. For example you might have some custom realurl rules that make your RSS feed accessible as rss.xml. You can skip rewriting to static file with the following condition:

RewriteCond %{REQUEST_FILENAME} !^.*\.xml$

Keep in mind: If you are using the gzip feature of StaticFileCache you have to take care, that the output is not encoded twice. If the result of the page are cryptic chars like "�‹��í[krÛH’þ-Eô�ª¹±-¹[ À—�É${dùÙkÙ�[îé..." remove the "text/html " in the mod_deflate section of the default TYPO3 .htaccess rules.
