Question

So, I am trying to make: sub.example.com/page rewrite to http://www.example.com/sub/page

I have this code which does work (note last character):

RewriteCond %{HTTP_HOST} !www.example.com$ [NC]
RewriteCond %{HTTP_HOST} ^([a-z0-9-]+).example.com [NC]
RewriteRule ^(.*) http://www.example.com/%1/$1 [R]

And this code that does not:

RewriteCond %{HTTP_HOST} !www.example.com$ [NC]
RewriteCond %{HTTP_HOST} ^([a-z0-9-]+).example.com [NC]
RewriteRule ^(.*) http://www.example.com/%1/$1 [L]

I want the url to remain as the user typed it in, but this seems to produce a 500 error. I’ve enabled logging to try to assist, but it doesn’t provide any clues. Is this possible?

Answer 1

Try changing the last Rule to

RewriteRule ^(.*) http://www.example.com/%1/$1 [P]

If you list your directory structure to show how sub.example.com and www.example.com are related, this may also be possible via a rewrite vs the more expensive (slower) proxy solution above.
