Apache Mod_Rewrite保持重定向

I'm trying to setup a site on my local Windows machine (PHP, Apache 2.4) and my redirect rules are creating an inifinite loop. I can't figure out why.

My hosts file:

127.0.0.1   learn.loc
127.0.0.1   www.learn.loc

My Apache httpd-vhosts.conf:

<VirtualHost *:80>
    DocumentRoot "C:\websites\learn"
    ServerName learn.loc
    ServerAlias www.learn.loc
    ErrorLog "logs/learn.loc-error.log"
    CustomLog "logs/learn.loc-access.log" common

    LogLevel alert rewrite:trace2

    #PHP SETTINGS
    php_value auto_prepend_file "C:\websites\learn
oop.php"
    php_value open_basedir "C:\websites\learn"
    php_value error_log "C:\websites\learn\php_error.log"

    <Directory "C:\websites\learn">
      Options Indexes FollowSymLinks
      AllowOverride All
      Require all granted
    </Directory>  
</VirtualHost>

The .htaccess (located in C:\websites\learn)

RewriteEngine on
RewriteRule ^yii   /yii-v1/blog
RewriteRule ^yii/(.*)   /yii-v1/blog/$1

The webpage I'm trying to access is at C:\websites\learn\yii-v1\blog\index.php. When I enter learn.loc/yii, the web browser is redirected indefinitely. The ModRewrite trace shows:

[rid#1330178/initial] rewrite 'yii/blog/' -> '/yii/blog'
[rid#1330178/initial] trying to replace context docroot C:/websites/learn with context prefix 
[rid#1330178/initial] internal redirect with /yii/blog [INTERNAL REDIRECT]
[rid#1331880/initial/redir#1] rewrite 'yii/blog' -> '/yii/blog'
[rid#1331880/initial/redir#1] trying to replace context docroot C:/websites/learn with context prefix 
[rid#1331880/initial/redir#1] internal redirect with /yii/blog [INTERNAL REDIRECT]
[rid#1334a40/initial/redir#2] rewrite 'yii/blog' -> '/yii/blog'
[rid#1334a40/initial/redir#2] trying to replace context docroot C:/websites/learn with context prefix 
[rid#1334a40/initial/redir#2] internal redirect with /yii/blog [INTERNAL REDIRECT]
[rid#1335b88/initial/redir#3] rewrite 'yii/blog' -> '/yii/blog'
[rid#1335b88/initial/redir#3] trying to replace context docroot C:/websites/learn with context prefix 
[rid#1335b88/initial/redir#3] internal redirect with /yii/blog [INTERNAL REDIRECT]
[rid#1336e30/initial/redir#4] rewrite 'yii/blog' -> '/yii/blog'
...

Notice that the request ids (first column) are different so there is some sort of infinite recursion happening, and I can't figure out why. There are no Apache or PHP errors.

    You must anchor your regex pattern in RewriteRule to avoid this problem:

    RewriteEngine on
    
    RewriteRule ^yii/?$   /yii-v1/blog [L,NC]
    
    RewriteRule ^yii/(.+)$ /yii-v1/blog/$1 [L,NC]
    

    Your regex pattern ^yii matches any URI that starts with /yii and since your rewritten URI is also starting with /yii hence it keeps rewriting until Apache mod_rewrite module reaches max limit set at Apache server level or by default i.e. 10.

    This limit can be changed in Apache config using this directive:

    RewriteOptions MaxRedirects=20
