	h3#art-1 #[a(href='#art-1') 1. Introduction]
	p Here I'll place recipes for implementing different functionalities and notes on webserver's behaviour.

	h3#art-2 #[a(href='#art-2') 2. Userdir functionality like Apache's mod_userdir]
	p Once I wanted to have a “tilde user directories” like #[code /~user/] which is more known as Apache's #[code mod_userdir] feature. I work with NGiNX so regular expressions is the way to do that.
	p Nothing special in my case. I only need to keep files there, so others may get them. Thing is simple, but I took some time to realise what regexp to use here back then.
	p The implementation is quite simple:
	pre
		| location ~ ^/~(.+?)(/.*)?$ {
		|     alias /home/$1/pub$2;
		|     autoindex on;
		| }
	p Of course, you can choose whatever place for user's public directories. In my case you need to give a read and execute permissions to user's home directory and to public directories inside them to others (#[code chmod o=rX /home/user]), which may be a security concern.
	p #[code autoindex on] will make an index of files that lies by URL. And, of course, you can put there an #[code index.html] file.

	h3#art-3 #[a(href='#art-3') 3. Note on how NGiNX works with HTTP headers]
	p Let's say in #[code http] block you specified common headers like #[code X-Frame-Options], #[code X-XSS-Protection], and so on for all #[code server] directives to use. But, if you add some other header for a specific #[code server] or #[code location] block then all those headers would be dropped.
	p For now the only cure for it is to place all that headers in a separate file like #[code common-headers.inc] and using #[code include] directive to include them in all the #[code server] and #[code location] blocks where additional headers are added.
