Implementing url rewriting using .htaccess file without affecting $_SERVER['SCRIPT_NAME']

Question

I want to setup a SaaS(Software as a Service) version of my ERP product. Each of the user who purchases the product can access the product using a url which will be specific for each user (For Example: erp.com/user1/). But there will not be a physical folder created for each user, it will be a virtual one and there will be a single copy of the program file will be there and which will be in the root directory.

I have tried with a htaccess file and here with include the code i have written, it is not generic solution it will work only for the case of 'folder1'

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule ^folder1/(.*)$ /$1 [QSA]
</IfModule> 

The problem is when I implement the $_SERVER['SCRIPT_NAME'] returns 'erp.com/', instead of this i need to get 'erp.com/folder1/' also please suggest me a generic solution for the problem.

Thank you.

Answer 1

Instead of $_SERVER["SCRIPT_NAME"] you need to use:

$_SERVER["REQUEST_URI"]

that will have value:

/folder1/foobar

Generic Rule:

RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^[^/]+/(.*)$ /$1 [L]
