Yii2 cannot reach the backend part - yii2-advanced-app

Question

I really don't get it how can i get to that backend .. How i installed the advanced template is like the way they show it in the official site : http://www.yiiframework.com/download/ . Everything step by step. When i try frontend.dev (in my case eshop) i am redirected to the front end part but when i try backend.dev(in my case eshop/admin) i am also redirected to the frontend.
This is my host file:
# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host
# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost
# 127.0.0.1 modules
127.0.0.1 eshop
127.0.0.1 eshop/admin
0.0.0.1 mssplus.mcafee.com
And the vhost.conf:
<VirtualHost *:80>
ServerName eshop
DocumentRoot "C:/xampp/htdocs/eshop/frontend/web/"
<Directory "C:/xampp/htdocs/eshop/frontend/web/">
# use mod_rewrite for pretty URL support
RewriteEngine on
# If a directory or a file exists, use the request directly
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# Otherwise forward the request to index.php
RewriteRule . index.php
# use index.php as index file
DirectoryIndex index.php
# ...other settings...
# Apache 2.4
Require all granted
## Apache 2.2
# Order allow,deny
# Allow from all
</Directory>
</VirtualHost>
<VirtualHost *:80>
ServerName eshop/admin
DocumentRoot "C:/xampp/htdocs/eshop/backend/web/"
<Directory "C:/xampp/htdocs/eshop/backend/web/">
# use mod_rewrite for pretty URL support
RewriteEngine on
# If a directory or a file exists, use the request directly
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# Otherwise forward the request to index.php
RewriteRule . index.php
# use index.php as index file
DirectoryIndex index.php
# ...other settings...
# Apache 2.4
Require all granted
## Apache 2.2
# Order allow,deny
# Allow from all
</Directory>
</VirtualHost>
Where is my mistake ? A lot of thanks in advance!

Answer 1

Using a slash (/) in hostname is illegal, as it is defined in RFC 952. Therefore in the URL "http://eshop/admin" the server name is "eshop" and apache is using of course your first virtual server setting.
Summarized, your idea will never work. You should use eshop-admin as server name.
