htaccess - allow multiple domain origins, force https, force www, rewrite url with subdirectory

Question

I would like to create an .htaccess to

1. allow origin (https://www.example.com and https://example.com and https://subdomain.example.com)
2. force https
3. force www
4. rewrite url with the subdirectory

---

Edit: Here is my new .htaccess file

    RewriteEngine on

    Header add Access-Control-Allow-Origin "https://www.example.com, https://example.com, https://subdomain.example.com"
    Header add Access-Control-Allow-Methods "PUT, GET, POST, DELETE, OPTIONS"
    Header add Access-Control-Allow-Headers "origin, x-requested-with, content-type, X-CSRF-Token"

    RewriteCond %{HTTP_HOST} !^www\. [NC,OR]
    RewriteCond %{HTTPS} off
    RewriteCond %{HTTP_HOST} ^(?:www\.)?(.+)$ [NC]
    RewriteRule ^ https://www.%1%{REQUEST_URI} [L,R=301,NE]

    RewriteRule ^(path/to/directory/file)/([^/]+)/?$ $1.php?u=$2 [NC,L,QSA]

Here is my .htaccess file

RewriteEngine on

Header add Access-Control-Allow-Origin "https://www.example.com, https://example.com, https://subdomain.example.com"
Header add Access-Control-Allow-Methods "PUT, GET, POST, DELETE, OPTIONS"
Header add Access-Control-Allow-Headers "origin, x-requested-with, content-type, X-CSRF-Token"

RewriteCond %{HTTP_HOST} ^example\.com$ [OR]
RewriteCond %{HTTP_HOST} ^www\.example\.com$

RewriteCond %{SERVER_PORT} 80 
RewriteRule ^(.*)$ "https\:\/\/www\.example\.com\/$1" [R=301]


RewriteRule ^path/to/directory/file/([^/]*)$ path/to/directory/file.php?u=$1 [L]

• This rule is working: (http://example.com/file/xxxx)

  RewriteRule ^file/([^/]*)$ path/to/directory/file.php?u=$1 [L]
  

• Edit: This rule is working (http://example.com/path/to/directory/file/xxxx)

  RewriteRule ^path/to/directory/file/([^/]*)$ path/to/directory/file.php?u=$1 [L]
  

Edit:

Think to remove the first slash after ^ to make it working as said in this subject.

Answer 1

Replace all of your existing code with this:

RewriteEngine on

Header add Access-Control-Allow-Origin "https://www.example.com, https://example.com"
Header add Access-Control-Allow-Methods "PUT, GET, POST, DELETE, OPTIONS"
Header add Access-Control-Allow-Headers "origin, x-requested-with, content-type, X-CSRF-Token"

RewriteCond %{HTTP_HOST} !^www\. [NC,OR]
RewriteCond %{HTTPS} off
RewriteCond %{HTTP_HOST} ^(?:www\.)?(.+)$ [NC]
RewriteRule ^ https://www.%1%{REQUEST_URI} [L,R=301,NE]

RewriteRule ^(path/to/directory/file)/([^/]+)/?$ $1.php?u=$2 [NC,L,QSA]

Make sure to clear your browser cache before testing this.

Allow Origin:

<IfModule mod_headers.c>
    Header set Access-Control-Allow-Origin "*"
</IfModule>

Force HTTPS:

RewriteEngine On
RewriteCond %{HTTPS} !=on
RewriteRule ^.*$ https://%{SERVER_NAME}%{REQUEST_URI} [R,L]

Force WWW:

Options +FollowSymLinks
RewriteEngine on
RewriteCond %{HTTP_HOST} ^example.com[nc]
RewriteRule ^(.*)$ http://www.example.com/$1 [r=301,nc]

URL to subdomain:

RewriteEngine On
RewriteCond %{HTTP_HOST} ^(www.)?example.com$
RewriteRule ^(/)?$ example [L]
