WordPress MU

Hello,

I want to redirect my user to http://mymu.installation.com/my_blog_a/ when he types http://mymu.installation.com/

Is this possible ?

Yes.

You didn't ask how is this possible, right? ;)

Well, how is this possible ? :D

enter this in your .htaccess file located inside your root, should do the trick

Redirect 301 http://mymu.installation.com/ http://mymu.installation.com/my_blog_a/

thank you Ovidiu.

The right sintax is :

Redirect 301 /index.html http://blog.atcasa.corriere.it/salone/

my pleasure but why would you have an index.html there?
