How to properly work with Yii htaccess and htpasswd?

Question

Yii

The first time a window popped up, but the verification failed. Now I can not repeat the focus.
Explain on the fingers pliz.

AuthName "Restricted Area" 
AuthType Basic 
AuthUserFile /home/mysite/.htpasswd 
AuthGroupFile /dev/null 
require valid-user

/home/mysite/ - in case of localhost it is /localhost/mysite/ ?
and in the case of the server /mysite.ru/mysite/ ?
Where to put htpasswd ? In a category below or above?
Is /protected enough for yii?
What about the server?
And what to do with the native htaccess? Is it easy to add?

AddDefaultCharset utf-8

Options +FollowSymLinks 
IndexIgnore */* 
RewriteEngine on

# if a directory or a file exists, use it directly 
RewriteCond %{REQUEST_FILENAME} !-f 
RewriteCond %{REQUEST_FILENAME} !-d

# otherwise forward it to index.php 
RewriteRule . index.php

php_value post_max_size 10M
php_value upload_max_filesize 10M
php_value max_execution_time 200
php_value max_input_time 200

and in general I had this -
yii (framework)
mysite (in the same folder) - here

AddDefaultCharset utf-8

Options +FollowSymLinks 
IndexIgnore */* 
RewriteEngine on

# if a directory or a file exists, use it directly 
RewriteCond %{REQUEST_FILENAME} !-f 
RewriteCond %{REQUEST_FILENAME} !-d

# otherwise forward it to index.php 
RewriteRule . index.php

php_value post_max_size 10M
php_value upload_max_filesize 10M
php_value max_execution_time 200
php_value max_input_time 200

### force www
   RewriteCond %{HTTP_HOST} ^www.(.+)$ [NC]
   RewriteRule ^(.*)$ http://%1/$1 [R=301,L]
   RewriteBase /

in the mysite/protected/.htaccess folder
deny from all
Explain on your fingers what is responsible for what and how to use it with and without yii.

Answer 1

Only applies to Yii

RewriteEngine on

# if a directory or a file exists, use it directly 
RewriteCond %{REQUEST_FILENAME} !-f 
RewriteCond %{REQUEST_FILENAME} !-d

# otherwise forward it to index.php 
RewriteRule . index.php

The rest is apache.
