Apache subdirectory as main server - apache

Question

I have a VirtualServer at api.host.com and I need to access the same content at app.host.com/api.
In Apache a have the following rule in httpd.conf :
<VirtualHost app.host.com>
DocumentRoot "C:\webserver\public\webapp"
ServerName app.host.com
<Directory "C:\webserver\public\webapp">
Options Indexes FollowSymLinks Includes ExecCGI
AllowOverride All
Require all granted
</Directory>
Alias /api/ "C:/webserver/public/api/"
<Directory "C:/webserver/public/api/">
Order allow,deny
Allow from all
Require all granted
Options Indexes FollowSymLinks
</Directory>
</VirtualHost>
And in C:/webserver/public/webapp, .htaccess is :
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php?_url=/$1 [QSA,L]
RewriteRule ^/api/(.*)$ /api/index.php?_url=/$1 [QSA,L]
RewriteRule ^api/(.*)$ api/index.php?_url=/$1 [QSA,L]
I'm getting 404 not found when I access app.host.com/api/test but in app.host.com/api it is all ok.
In C:/webserver/public/api, .htaccess is :
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php?_url=/$1 [QSA,L]
And works just fine with api.host.com/test.

Answer 1

You need to swap the order of your rules. Your first rule's ^(.*)$ regex is matching all of your requests, so you need your api stuff before that rule gets a chance to match the request. Something like this:
RewriteEngine On
RewriteRule ^/?api/(.*)$ /api/index.php?_url=/$1 [QSA,L]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php?_url=/$1 [QSA,L]

Answer 2

In httpd.conf, I changed the path to
Alias /**apicall**/ "C:/webserver/public/api/"
<Directory "C:/webserver/public/api/">
Order allow,deny
Allow from all
Require all granted
Options Indexes FollowSymLinks
</Directory>
And used Jon Lin hint, changing .htaccess rule to
RewriteRule ^api/?(.*)$ /apicall/index.php?_url=/$1 [QSA,L]
