Htaccess redirector ?

[Anon]

Hi ,

How could i do this in Php or apache .
I have a page , and then a Extranet option that the user enter his/her login and password .

Then will be redirected to a secure page under my site .

But works like this :
If user is carlos we will be redirected to http://helldawmdummyaskstupidquestionshere.html
if user is michael we will be redirect to http://blablabla.html

etc etc

I wanna make a extranet diferent to every user .
How could i make this with apache and php ?

Thanks .
