Question

I have three folders in my document root –

localhost/myMainProject/   
localhost/myMainProjectSubdomain/  
localhost/myThirdProject/

I want to do the achieve following URL mapping –

www.mymainproject.com ---> localhost/myMainProject/
mysubdomain.mymainproject.com ---> localhost/myMainProjectSubdomain/
www.mythirdproject.com ---> localhost/myThirdProject/

I tried to change my hosts file to :

127.0.0.1/myMainProjectSubdomain mysubdomain.mymainproject.com
127.0.0.1/myMainProject www.mymainproject.com 
127.0.0.1/myThirdProject www.mythirdproject.com

But this doesnt work. I think I have to create some .htaccess file or something somewhere but have no idea how that works.

Is this possible ? Please guide me on how this can be achieved. Thanks.

Put this in your htaccess file in the document root:

RewriteEngine On

# for www.mymainproject.com
RewriteCond %{HTTP_HOST} ^(www\.)?mymainproject\.com$ [NC]
RewriteCond %{REQUEST_URI} !^/myMainProject
RewriteRule ^(.*)$ /myMainProject/$1 [L]

# for mysubdomain.mymainproject.com
RewriteCond %{HTTP_HOST} ^mysubdomain.mymainproject\.com$ [NC]
RewriteCond %{REQUEST_URI} !^/myMainProjectSubdomain
RewriteRule ^(.*)$ /myMainProjectSubdomain/$1 [L]

# for www.mythirdproject.com
RewriteCond %{HTTP_HOST} ^(www\.)?mythirdproject\.com$ [NC]
RewriteCond %{REQUEST_URI} !^/myThirdProject
RewriteRule ^(.*)$ /myThirdProject/$1 [L]
