You can set up a virtualhost's in your httpd.conf

NameVirtualHost *

<VirtualHost *>
DocumentRoot /var/www/html/
ServerName example.com
</VirtualHost>

<VirtualHost *>
DocumentRoot /home/user/public_html/blog/
ServerName blog.example.com
</VirtualHost>

Is there a way to do this for those of us who do not have access to http.conf? (ie .htaccess)

[lemat]

I belive you can't do this without httpd.conf

I don't have access to httpd.conf, only .htaccess
I have a linux account in a hosting company.

Here's some pseudo-code to get you going:

If REQUEST_URI contains

/blog/

and HTTP_HOST is

www.example.com.br

, redirect (301 or 302) to

http://blog.example.com.br/

.

If HTTP_HOST is

blog.example.com.com.br

, do a silent redirect to the page for

www.example.com.br/blog/

.

Paulowolf, Welcome to Webmasterworld.
Two things.
1st - you have to remove your domain name, since it violates the rules of webmasterworld. Use a pseudo-domain
2nd - I have put psuedo-code suggested by closed into working code. I do know how well this will work, and I see no serious problems caused by your web host rewrite rule.
However, here is the code that you put into your .htaccess file

RewriteCond %{HTTP_HOST} ^www\.example\.com [NC]
RewriteCond %{REQUEST_URL} ^/blog/
RewriteRule ^(.*) [blog.example.com$1...] [R=301,L]
RewriteCond %{HTTP_HOST} ^(blog)\.example\.com [NC]
RewriteRule ^(.*) [example.com...] [L]
