Hi guys trying to get a 301 redirect working and having trouble. I need to redirect sub.domain1.com to www.domain2.com and make sure that any file names or parameters get sent over with it.
This is what I was trying:
RewriteCond %{HTTP_HOST} ^domain1.com [NC]
RewriteRule ^(.*)$ http://www.domain2.com/$1 [L,R=301]
I also tried this:
RewriteCond %{QUERY_STRING} ^$
RewriteRule ^sub\.domain1\.com$ /www.domain2.com? [R=301,NE,NC,L]
Where am I messing up?
回答1:
Rule of thumb for rewriterules: from the most complex to the less complex. And don't forget the QSA directive (QSA = Query String Append = "make sure that any file names or parameters get sent over with it")
RewriteCond %{HTTP_HOST} ^sub\.domain1\.com$ [NC]
RewriteRule ^(.*)$ http://www.domain2.com/$1 [QSA,R=301,L]
Tell me if it works.
回答2:
You missed the subdomain part and proper escaping.
RewriteCond %{HTTP_HOST} ^sub\.domain1\.com$ [NC]
RewriteRule ^(.*)$ http://www.domain2.com/$1 [L,R=301]
