HTAccess“镜像域”，尊重SSL，尊重co.uk + .com，保留子域和request_uri

Question

I would like to map multiple domains onto a main one for SEO and simplicity purposes.

My three domains are

webdevguru.co.uk
t3chguy.co.uk
mortie.org

I want both of the example domains to get redirected to the main domain, keeping their subdomain and the file and query string the client accessed.

For example:

str.webdevguru.co.uk => str.webdevguru.co.uk/
webdevguru.co.uk     => www.webdevguru.co.uk/
fusion.t3chguy.co.uk => fusion.webdevguru.co.uk/
mortie.org/foo?bar   => www.webdevguru.co.uk/foo?bar
https://mortie.org/  => https://www.webdevguru.co.uk/

Basically, I want ALL traffic redirected to the main domain, this also has to respect HTTPS as the domain cms gets transferred to a different URL, my subfolder containing the cms subdirectory files has the following code in the .htaccess.

RewriteEngine on
RewriteCond %{HTTP_HOST} ^cms\.webdevguru\.co\.uk$ [NC]
RewriteRule .* https://secure24447.qnop.net/~t3chguy/tools/cms%{REQUEST_URI} [R=301,L]

This second code works absolutely fine I am just showing it to further explain my example. I keep having issues with any regex I keep trying, it works in one way but not in another, could some people please suggest what I could do to get the above functionality?

Thanks in Advance

Answer 1

Ok, I give it a try :

# simple rule to redirect mainexample.co.uk to www.mainexample.co.uk
RewriteCond %{HTTPS} !=on [NC]
RewriteCond %{HTTP_HOST} ^[^\.]+\.(com|co\.uk|org)$ [NC]
RewriteRule ^(.*)$ http://www.mainexample.co.uk/$1 [R=301,QSA,L]

# same, with HTTPS
RewriteCond %{HTTPS} =on [NC]
RewriteCond %{HTTP_HOST} ^[^\.]+\.(com|co\.uk|org)$ [NC]
RewriteRule ^(.*)$ https://www.mainexample.co.uk/$1 [R=301,QSA,L]

# here comes the funny part
RewriteCond %{HTTPS} !=on [NC] # no HTPPS
RewriteCond %{HTTP_HOST} ^(.+)\.(.+)\.(com|co\.uk|org) [NC] # capture the subdomain
RewriteCond %{HTTP_HOST} !mainexample\.co\.uk$ [NC] # we are not on mainexample.co.uk
RewriteRule ^(.*)$ http://%1.mainexample.co.uk/$1 [R=301,QSA,L] # 301 redirection to mainexample keeping the subdomain and the request uri

# same, for HTTPS
RewriteCond %{HTTPS} =on [NC]
RewriteCond %{HTTP_HOST} ^(.+)\.(.+)\.(com|co\.uk|org) [NC]
RewriteCond %{HTTP_HOST} !mainexample\.co\.uk$ [NC]
RewriteRule ^(.*)$ https://%1.mainexample.co.uk/$1 [R=301,QSA,L]

There no need to duplicate rules for http and https, but I don't know how to do one only rule.

Edit regarding your HTTPS issue :

RewriteCond %{HTTPS} =on [NC]
RewriteCond %{HTTP_HOST} ^(cms|fusion)\.[^\.]+\.(com|co\.uk|org)$ [NC]
RewriteRule ^(.*)$ https://secure27.qnop.net/~t3chguy/%1/$1 [R=301,QSA,L]

Answer 2

You can use these rules:

RewriteEngine on

RewriteCond %{HTTP_HOST} ^cms\.mainexample\.co\.uk$ [NC]
RewriteRule .* https://secure24447.qnop.net/~t3chguy/tools/cms%{REQUEST_URI} [R=301,L]

RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteCond %{HTTP_HOST} ^[^.]+\.webdevguru\. [NC]
RewriteRule ^ - [L]

RewriteCond %{HTTP_HOST} ^webdevguru\. [NC,OR]
RewriteCond %{HTTP_HOST} ^(?:www\.)?mortie\.org$ [NC]
RewriteRule ^ http%{ENV:protossl}://www.webdevguru.co.uk%{REQUEST_URI} [R=301,L,NE]

RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteCond %{HTTP_HOST} ^([^.]+)\.[^.]+\.[^.]+\. [NC]
RewriteRule ^ http%{ENV:protossl}://%1.webdevguru.co.uk%{REQUEST_URI} [R=301,L,NE]
