Web Hosting Talk : Web Hosting Main Forums : Hosting Security and Technology : Correct 301 moved permanently code

[NameSniper]

Hello,

I am trying to push my server to return Moved Permanently code and redirect these URLs to the main URL, but cant find the right code.
domain.com
w.domain.com
ww.domain.com
wwww.domain.com
to
www.domain.com

There are a number of codes available on the net and all supposed to do that, but which one is the eight one?

1)
Options +FollowSymlinks
RewriteEngine on
rewritecond %{http_host} ^domain.com [nc]
rewritecond %{http_host} ^w.domain.com [nc]
rewritecond %{http_host} ^ww.domain.com [nc]
rewritecond %{http_host} ^wwww.domain.com [nc]
rewriterule ^(.*)$ http://www.domain.com/$1 [r=301,nc]

2)
Options +FollowSymLinks
RewriteEngine on
RewriteCond %{HTTP_HOST} ^example\.com
RewriteCond %{HTTP_HOST} ^w.example\.com
RewriteCond %{HTTP_HOST} ^ww.example\.com
RewriteCond %{HTTP_HOST} ^wwww.example\.com
RewriteRule ^(.*)$ http://www.example.com/$1 [R=permanent,L]

3)
Options +FollowSymLinks
RewriteEngine On
RewriteCond %{HTTP_HOST} ^domain\.com$ [NC]
RewriteCond %{HTTP_HOST} ^w.domain\.com$ [NC]
RewriteCond %{HTTP_HOST} ^ww.domain\.com$ [NC]
RewriteCond %{HTTP_HOST} ^wwww.domain\.com$ [NC]
RewriteRule ^(.*)$ http://www.domain.com/$1 [R=301,L]

This one?

Options +FollowSymLinks
RewriteEngine On

RewriteBase /

# These first set of rules makes sure that visitors
# are viewing the WWW domain i.e. www.jhive.net
Rewritecond %{HTTP_HOST} !^www\.jhive\.net
RewriteRule (.*) http://www.jhive.net/$1/ [R=301,L]

It doesnt seems to be what I am looking for.
Anything else?

[zoticaic]

What exactly are you trying to achieve? i.e. if the domain is not like www.domain.com then redirect to that domain via 301?

I think that's exactly the solution, just have to change jhive.net to your correct domain.

No, I want domain.com/* w.domain.com/* ww.domain.com/* wwww.domain.com/* to return moved permanently and redirect to the same page but at www.domain.com
For example is someone visits domain.com/somepage he should be taken to www.domain.com/somepage. Same about w.domain.com ww and wwww.
Is it possible?

[foobic]

That's exactly what the code above does (the $1 substitutes your "somepage"). Most likely w. ww. and wwww.domain.com won't resolve though - you'd also need to add those as parked domains if you want them handled properly.

You fergot to say OR in your rules.

You're asking it to match a host which is domain.com, w.domain.com, ww.domain.com, AND wwww.domain.com (which it could only be one of)

Options +FollowSymlinks
RewriteEngine on
rewritecond %{http_host} ^domain.com [OR]
rewritecond %{http_host} ^w.domain.com [OR]
rewritecond %{http_host} ^ww.domain.com [OR]
rewritecond %{http_host} ^wwww.domain.com
rewriterule ^(.*)$ http://www.domain.com/$1 [r=301]

[foobic]

Rewritecond %{HTTP_HOST} !^www\.jhive\.net

The one condition specifies any domain that is not www.domain.com, so it automatically handles all of those without needing the extra lines and multiple [OR]s.

rewriterule ^(.*)$ http://www.domain.com/$1 [r=301]

I'll try this out, thanks.

That code will return 301 for any subdomain except www.domain.com right?
Thats not what I need as I have a number of working subdomains and dont want to affect them.

This will not affect other subdomains the rewrite rules are effective only on the current ServerName/ServerAlias

For example if you have:

ServerName domain.com
ServerAlias www.domain.com

Apache will only redirect request to the corresponding virtual host block if the the specified domain is any of the above, and then the rewriting engine kicks in.

No, namesniper's right - where the subdomain has its document root in a subdirectory of the main domain's (the default setup for several control panels) the .htaccess in the parent directory will affect the subdomain. It doesn't feel right to me that this should happen but it does, and it's documented.

Where you have a number of subdomains that you want to match and a number of others you want to leave unaffected you have a choice of either using lightwave's suggestion (specify exactly what you want to match) or modifying zoticaic's to specify all those you don't want to match, ie.

Rewritecond %{HTTP_HOST} !^www\.example\.com
Rewritecond %{HTTP_HOST} !^sub1\.example\.com
Rewritecond %{HTTP_HOST} !^sub2\.example\.com
RewriteRule (.*) http://www.example.com/$1/ [R=301,L]

[NameSniper]

This code has worked out

Options +FollowSymlinks
RewriteEngine on
rewritecond %{http_host} ^domain.com [OR]
rewritecond %{http_host} ^w.domain.com [OR]
rewritecond %{http_host} ^ww.domain.com [OR]
rewritecond %{http_host} ^wwww.domain.com
rewriterule ^(.*)$ http://www.domain.com/$1 [r=301]

I had a problem with w ww wwww domains, but this happens to be my control panel causing an issue.
In DirectAdmin you should add domain pointers like w.domain.com ww.domain.com and wwww.domain.com AND add them as an alias.

Rewritecond %{HTTP_HOST} !^sub2\.example\.com
RewriteRule (.*) http://www.example.com/$1/ [R=301,L]

Above code will exclude sub1 and sub2 from the list of moved sites?

[NameSniper]

I was also in the need of redirecting whole website except subdomain help.domain.com and this URL domain.com/admin.

Foobic suggested to use REQUEST_URI instead HTTP_HOST variable in .htaccess and it has worked out.

The code is

Options +FollowSymlinks
RewriteEngine on
RewriteCond %{REQUEST_URI} !^/admin
Rewritecond %{HTTP_HOST} !^help\.domain\.com
RewriteRule (.*) http://www.domain2.com/$1 [R=301,L]

Thanks for sharing.
