htaccess rewrite based on domain - php

Question

my project has multiple domains and I would like to redirect 100 pages for 1 of these domain.
Now I found this post on how to set up conditions for 1 domain.
RewriteCond %{HTTP_HOST} ^www\.site1\.com [NC]
RewriteRule ^(.*)$ index.php?lang=it [NC,QSA]
RewriteCond %{HTTP_HOST} ^www\.site2\.com [NC]
RewriteRule ^(.*)$ index.php?lang=en [NC,QSA]
My question would be, how can I set this up for 100 pages?
Do I have to duplicate the condition for each link?
What I want to do is this
RewriteCond %{HTTP_HOST} ^www\.site1\.com [NC]
RewriteRule ^some https://www.mypage.de/shop/some [R=301, L]
RewriteRule ^page https://www.mypage.de/shop/page [R=301, L]
RewriteRule ^settings https://www.mypage.de/shop/settings [R=301, L]

Answer 1

There are so many scenarios to do in this case , for example , you could redirect every page except specific page like this :
RewriteCond %{HTTP_HOST} ^(www\.)?site1\.com [NC]
RewriteCond %{REQUEST_URI} !^/(page1|page2|page3|whatever)
RewriteRule ^(.*)$ https://www.mypage.de/shop/$1 [R=301, L]
But , if the number of page who should be excluded is large , you could create directory , for example , new then move all files that have to be redirected at it , then make this rule
RewriteCond %{HTTP_HOST} ^(www\.)?site1\.com [NC]
RewriteCond %{REQUEST_URI} !^/new/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{DOCUMENT_ROOT}/new%{REQUEST_URI} -f
RewriteRule ^(.*)$ /new/$1 [L]
Then you could add this to redirect any URI contains new to that new location :
RewriteCond %{HTTP_HOST} ^(www\.)?site1\.com [NC]
RewriteCond %{REQUEST_URI} ^/new/
RewriteRule ^(.*)$ https://www.mypage.de/shop/$1 [R=301, L]
So code should look like this :
RewriteCond %{HTTP_HOST} ^(www\.)?site1\.com [NC]
RewriteCond %{REQUEST_URI} !^/new/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{DOCUMENT_ROOT}/new%{REQUEST_URI} -f
RewriteRule ^(.*)$ /new/$1 [L]
RewriteCond %{HTTP_HOST} ^(www\.)?site1\.com [NC]
RewriteCond %{REQUEST_URI} ^/new/
RewriteRule ^(.*)$ https://www.mypage.de/shop/$1 [R=301, L]

Answer 2

Assuming your page names are same after redirect as you've shown in your question, you can use a single rule like this as your top most rule:
RewriteEngine On
RewriteCond %{HTTP_HOST} ^www\.site1\.com$ [NC]
RewriteRule .+ https://www.mypage.de/shop/$0 [R=301,NE,L]
Make sure to use a new browser for your testing.

Answer 3

Probably Skip flag will be the best aproach.
It looks like this:
RewriteCond %{HTTP_HOST} !^www\.site1\.com [NC]
RewriteRule .? - [S=100]
RewriteRule ^some https://www.mypage.de/shop/some [R=301, L]
RewriteRule ^page https://www.mypage.de/shop/page [R=301, L]
RewriteRule ^settings https://www.mypage.de/shop/settings [R=301, L]
.....
RewriteRule ^rule_for_100nd_page https://www.mypage.de/shop/settings [R=301, L]
How this works.
Test HOST if NOT skip 100 (S=100) the next RewriteRules if YES RewriteRule .? - [S=100] is ignored
Write your 100 rules for www.site1.com source domain and go on.

Answer 4

RewriteRule ^(.*)$ https://www.mypage.de/shop/$1 [QSA]
This will redirect every single page.
If you only want 100 specific pages you must add one by one. Like other answers were provided.

Answer 5

So after testing some of the suggestions I ended up having to add the condition to each rule in order to make it work.
So as far as I can tell you can't set conditions for more than one rule if the targets are to specific.
So my solution for this issue looks like this.
Thanks for all the suggestions.
RewriteCond %{HTTP_HOST} ^www\.site1\.com [NC]
RewriteRule ^some https://www.site1.de/shop/some [R=301, L]
RewriteCond %{HTTP_HOST} ^www\.site1\.com [NC]
RewriteRule ^page https://www.site1.de/random/page [R=301, L]
RewriteCond %{HTTP_HOST} ^www\.site1\.com [NC]
RewriteRule ^settings https://www.site1.de/whatever/settings [R=301, L]
