htaccess - subdomain question

[kbc1]

Hi

I am uploading a site and CMS to a host in Korea. They do not support subdomain creation (mental I know) so they have said I need to use htaccess redirect.

Now my CMS uses tidy/friendly URL's so its normall hosted on a subdomain as such:

admin.mydomain.com

And then all the pages are served as such:

admin.mydomain.com/user-management

Now if I upload my CMS to the Korean hosts, the admin system would be accessible via:

mydomain.com/adminfolder

But this would include the 'adminfolder' within all URL's which will break my CMS.

Is there a way through htaccess that I can tell the server that any request for "admin.mydomain.com" should server pages from mydomain.com/adminfolder??

Thanks for reading.

If your host supports wildcard DNS entries, yes: you can use mod_rewrite on the subdomain part:

RewriteCond %{HTTP_HOST} ^([^\.]*)\.example\.com [NC]
RewriteRule (.*) virtualsubdomains/%1/$1 [L,QSA]

...or something like. I've done this before, but I don't have it in front of me.

Something to consider is that, if your CMS can't even re-map urls to work on a single domain, then this sort of rewriting might cause you grief as well.

*however, if they don't support subdomains, I wouldn't expect them to support widlcard DNS entries.
