# READ THIS COMPLETELY IF YOU CHOOSE TO USE THIS FILE!

#

# The line 'Options +FollowSymLinks' may cause problems with some server configurations.

# It is required for the use of Apache mod_rewrite, but it may have already been set by

# your server administrator in a way that disallows changing it in this .htaccess file.

# If using it causes your site to produce an error, comment it out (add # to the

# beginning of the line), reload your site in your browser and test your sef urls. If

# they work, then it has been set by your server administrator and you do not need to

# set it here.

##

## MISSING CSS OR JAVASCRIPT ERRORS

#

# If your site looks strange after enabling this file, then your server is probably already

# gzipping css and js files and you should comment out the GZIP section of this file.

##

## OPENLITESPEED

#

# If you are using an OpenLiteSpeed web server then any changes made to this file will

# not take effect until you have restarted the web server.

##

## Can be commented out if causes errors, see notes above.

RewriteEngine On

## Begin - Rewrite rules to block out some common exploits.

# If you experience problems on your site then comment out the operations listed

# below by adding a # to the beginning of the line.

# This attempts to block the most common type of exploit `attempts` on Joomla!

#

# Block any script trying to base64_encode data within the URL.

RewriteCond %{QUERY_STRING} base64_encode[^(]*\([^)]*\) [OR]

# Block any script that includes a <script> tag in URL.

RewriteCond %{QUERY_STRING} (<|%3C)([^s]*s)+cript.*(>|%3E) [NC,OR]

# Block any script trying to set a PHP GLOBALS variable via URL.

RewriteCond %{QUERY_STRING} GLOBALS(=|\[|\%[0-9A-Z]{0,2}) [OR]

# Block any script trying to modify a _REQUEST variable via URL.

RewriteCond %{QUERY_STRING} _REQUEST(=|\[|\%[0-9A-Z]{0,2})

# Return 403 Forbidden header and show the content of the root home page

RewriteRule .* index.php [F]

#

## End - Rewrite rules to block out some common exploits.

## Begin - Custom redirects

#

# If you need to redirect some pages, or set a canonical non-www to

# www redirect (or vice versa), place that code here. Ensure those

# redirects use the correct RewriteRule syntax and the [R=301,L] flags.

#

## End - Custom redirects

##

# Uncomment the following line if your webserver's URL

# is not directly related to physical file paths.

# Update Your Joomla! Directory (just / for root).

#

# PHP FastCGI fix for HTTP Authorization, required for the API application

# If the requested path starts with /api, the file is not /api/index.php

## GZIP

## These directives are only enabled if the Apache mod_headers module is enabled.

## directly or fallback to gzip any asset on the fly

## If your site starts to look strange after enabling this file, and you see

## then your server is already gzipping css and js files and you don't need this

## block enabled in your .htaccess
