通过.htaccess实时运行子域+从URL隐藏子目录

Question

Currently I'm trying to have an environment that allows me to create a subdomain by creating subdirectory on the fly.

Directory tree,

domain.com
  ├── 1
  |   └── product1
  |   └── index.html
  ├── 2
  │   └── product2
  └── 3
      └── product3

.htaccess rule,

#Redirect subdomain to subdirectory
RewriteCond %{HTTP_HOST} ^([^\.]+).domain.com$
RewriteCond %{DOCUMENT_ROOT}/%1 -d
RewriteRule ^ %{DOCUMENT_ROOT}/%1%{REQUEST_URI} [QSA

Now, I have managed to use the .htaccess rule above to redirect me when I type in "1.domain.com" to reach index.html under subdirectory 1.

But if I go to "1.domain.com/product1" I will reach to my product1 page but the URL will show as "1.domain.com/1/product1".

How can I hide the "1" between the domain.com and product1 such that it will still show as "1.domain.com/product1" but in the background it will access "1.domain.com/1/product1" directory?

I have done a lot of research and found that usually people will ask to hard code the name of the directory but it won't work in this case because people will create subdirectories on the fly to get different subdomains so I will need a generic .htacess rule to handle this.

How can I achieve this?

Appreciate your help!

To rewrite

• /product1

to

• /1/product1

You can use the following rule :

RewriteRule ^((?!1).+)$ /1%{REQUEST_URI} [NC,L]
