General

Rule	Description
Options -Indexes	Enabled by default: Users can browse inside directory that doesn't have a index file (.html, .php, etc.). Turning it off, prevents from listing files of directories.
RewriteEngine On	Turns rewrite engine on - enable to write your own rules.
RewriteCond %{REQUEST_FILENAME} !-d	Rule condition 1, requested URL is not a directory
RewriteCond %{REQUEST_FILENAME} !-f	Rule condition 2, requested URL is not a file
RewriteRule ^([^\.]+)$ $1.html [NC,L]	If both conditions are passed (1 & 2), "Smart link" works. Request to bambit.com.pl/[name] will be identical to bambit.com.pl/[name.html]. Both URLs works, but user has not to enter full URL.
RewriteCond %{HTTPS} off [OR] RewriteCond %{HTTP_HOST} ^www. [NC]	Automatically redirects request to HTTPS. E.g. URL http://bambit.com.pl, will be changed to https://bambit.com.pl.
RewriteRule ^ https://bambit.com.pl/%{REQUEST_URI} [L,NE,R=301]	Domain prefix 'www' will be remove. E.g. URL https://www.bambit.com.pl will be changed to https://bambit.com.pl

Safety

Header name	Description
Content-Security-Policy	Content Security Policy is an effective measure to protect your site from XSS attacks. By whitelisting sources of approved content, you can prevent the browser from loading malicious assets. Analyse this policy in more detail. You can sign up for a free account on Report URI to collect reports about problems on your site.
X-Content-Type-Options	X-Content-Type-Options stops a browser from trying to MIME-sniff the content type and forces it to stick with the declared content-type. The only valid value for this header is "X-Content-Type-Options: nosniff".
X-FRAME-OPTIONS	X-Frame-Options tells the browser whether you want to allow your site to be framed or not. By preventing a browser from framing your site you can defend against attacks like clickjacking.
X-XSS-Protection	X-XSS-Protection sets the configuration for the XSS Auditor built into older browser. The recommended value was "X-XSS-Protection: 1; mode=block" but you should now look at Content Security Policy instead.
Strict-Transport-Security	HTTP Strict Transport Security is an excellent feature to support on your site and strengthens your implementation of TLS by getting the User Agent to enforce the use of HTTPS.
Referrer-Policy	Referrer Policy is a new header that allows a site to control how much information the browser includes with navigations away from a document and should be set by all sites.
Permissions-Policy	Permissions Policy is a new header that allows a site to control which features and APIs can be used in the browser.
