--------

RewriteEngine on
RewriteCond %{HTTP_HOST}!^(www\\.)?example\\.com [NC]
RewriteCond %{HTTP_HOST} ^(.*)\\.example\\.com [NC]
RewriteRule .* [example.com...] [R=301,L]

Remove the double backslashes for a start:

RewriteEngine on
RewriteCond %{HTTP_HOST} !^(www\.)?example\.com [NC]
RewriteCond %{HTTP_HOST} ^(.+)\.example\.com [NC]
RewriteRule .* http://www.example.com/blog/%1 [R=301,L]

finally!

thanx, of course it would be something small...

[hershko]

darn, spoke too soon.

its redirecting ALL subdomains, including valid ones.
i.e. forum.example.com used to go to www.example.com/forum/ but now its also being rewritten by the new htaccess code...

:(

how can i include some exceptions to what i have?

thanx again!

I'm sorry... Exactly how do you define a "valid subdomain" and an "invalid subdomain"?

What information does the server have that you need to test?

valid subdomains lead to subdirectories that i have already created i.e. mail.example.com and forum.example.com

invalid subdomains lead to user-created subdirectories that are created by my site
for example:
user1.example.com leads to www.example.com/blog/user1
user2.example.com leads to www.example.com/blog/user2

the code above is correctly directing the user-created subdomains to their appropriate subdirectories, but now its also redirecting my valid subdomains like mail and forum to:
www.example.com/blog/mail
and
www.example.com/blog/forum

argh! i think i have to separately specify all my valid subdomains...

[jdMorgan]

Yes, add them to the first RewriteCond:

RewriteCond %{HTTP_HOST}!^[b]((www¦blog¦forum)\.)[/b]?example\.com [NC]

Change the broken pipe "¦" characters to solid pipe characters before use -- usually Shift-\ on the keyboard.
