remapping dynamic subdomain

Hi, I'm working on a web app and want to be able to offer my users a URL such as:

username.mydomain.com

but have it map to:

mydomain.com/controller/method/username

FYI, I'm using codeigniter PHP framework, which should explain the above URL I need to map to.

I'm thinking this should be done with mod_rewrite, and I've tried various method to no avail. Any ideas on how to go about this?

Thanks for any insights!

I'm afraid you'll likely need access to the server's setup. No idea how you'd go about it, though.

Hey Markus,

I have a vps, so I can do what ever. I'm just not sure exactly how to set it up. I added a wildcard domain, so all subdomains resolve, I just need the .htaccess to pick up the slack.

I actually had something working OK, but it redirected all subdomains. There are some I do not want redirected, like the main application, the demo version, the dev version, etc...all which are on their own subdomain.

So I need like a list of domains not to remap, and anything else should get kicked to a specific url.

Thanks for your reply!

You can use the RewriteCond stuff for that. Something like this (untested):

I will do some testing to find the correct syntax.

Hey no problem Markus, I appreciate your input. Ok, so it's fairly simple it looks like, I think the hardest part is figuring out how to phrase the google query to find what I'm looking for. I should have guessed it would be ! (not) this domain.

I'll see what I can work out with this. Thanks again!

I think my above syntax is correct. For multiple sites, you could do this:

i just spent all day trying to figure this one out for myself. i started off not even knowing how to use regex to feeling like a guru on this one. i pieced this information from the internet and it has nothing to do with codeigniter but it works for me. like i said i'm still a beginner so any critique of this code is welcome

so http://ann-marie_jones.thedomain.com
displays http://www.thedomain.com/profile/?first=ann-marie&last=jones

as long as a wildcard subdomain is set up, this code should be good to go
