Resolved About specifying fastcgi_pass in Plesk

[Zoo3]

I wondered when I looked into Plesk's nginx.conf file.

/etc/nginx/plesk.conf.d/vhosts/hostname.com.conf
fastcgi_pass "unix:///var/www/vhosts/system/SUB-DOMAIN/php-fpm.sock";

As described above, in fastcgi_pass, slashes are input consecutively three times like "unix:///var/".
Please tell me the meaning of three consecutive slashes. Is there any difference from the single slash case?

It's like `http://`, but `unix://`.
The third slash is the root of the path `/var/www/vhosts/system/SUB-DOMAIN/php-fpm.sock`

Does this specification affect performance? This specification looks like Plesk only.
For example, "vi /var/text.txt" and "vi ///var/text.txt" will edit the same file.

In the html source, is it treated to indicate the target with either http or https?
When there is a possibility of making http connection and https connection in the same domain, it may be written like "//img/src/sample.jpg". Is this the same thing?

Does this specification affect performance?

No. It is just specification, an indication of how to exchange information. Another example file:///usr/share/doc/packet/index.html
In our case, it is a unix socket but not the file.

Excuse me, I can not understand anything. Is this a specification method that only Plesk is unique, and does not need to know the meaning?

How many slashes?
file URI scheme - Wikipedia
Or
Uniform Resource Identifier - Wikipedia
