how do i redirect a domain name to an alternate on the same site? i.e example1.com to example2.com; both the same site via htaccess? - apache

All the examples I've found have something along the lines of
RewriteCond %{HTTP_HOST} ^olddomain.com$ [OR]
RewriteCond %{HTTP_HOST} ^www.olddomain.com$
RewriteRule (.*)$ https://www.newdomain.com/$1 [R=301,L]
But it doesn't seem to catch in my .htaccess despite online syntax checkers telling me everything is fine and it'll fire.
I have a bunch of non conflicting individual page RewriteRules that don't conflict with this and fire off fine so I know mod rewrite is working and i'm stumped.
olddomain is a domain that used to reside on a different server but its dns is being pointed at newdomain so all these rules are firing off on the same site if that matters

Why is the htaccess in my subdomain folder overriding aspects of the htaccess in my main domain?

Let me explain my setup here, I have two domains, for the sake of naming them lets call them domain1.com and domain2.com. I have shared hosting that runs cPanel.
Domain1.com is my main domain, and is what I have my hosting account setup using. I have a website hosted at that domain. Domain2.com is set as an add-on domain, and directs to a folder inside of the main domains root. That has it's own website (a Ghost blog).
That all works fine. However the websites hosted at the two domains are quite different and I did not want the subdomain to work, but as far as I can tell add-on domains in cPanel have to have a subdomain in order to be added to the account. The redirect options for the subdomains in cPanel aren't good enough for me, as I wanted anyone accessing say domain1.com/domain2 to get a 404 error as if it didn't exist. So I set up the .htaccess file for domain1.com to look like this:
RewriteEngine On
#301 (permenant) redirects all HTTP requests to HTTPS (SSL)
RewriteCond %{HTTPS} !on
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
#404 redirects all domain.com/subdomain requests
RewriteCond %{HTTP_HOST} ^(www.)?domain1.com$ [NC]
RewriteCond %{REQUEST_URI} ^/domain2/(.*)$
RewriteRule ^(.*)$ - [L,R=404]
#404 redirects all subdomain.domain.com & www.subdomain.domain.com requests
RewriteCond %{HTTP_HOST} ^domain2.domain1.co.uk$ [OR]
RewriteCond %{HTTP_HOST} ^www.domain2.domain1.co.uk$ [OR]
RewriteCond %{REQUEST_URI} ^/$
RewriteRule ^(.*)$ - [L,R=404]
This worked perfectly, anyone tryting to access domain2 via domain1 would get a 404 error. But that was before I installed Ghost on domain2 After getting Ghost installed I created an .htaccess file in the domain2 folder inside of domain1's root.I had to put this in it in order for Ghost for to run, as it uses NodeJS:
RewriteEngine on
RewriteRule ^(.*)$ http://127.0.0.1:55555555/$1 [P,L]
This also works perfectly except for one aspect. Now all requests to the domain using domain1.com have started working again. For example if I type domain2.domain1.com it will now show me the Ghost blog where as before it was correctly displaying a 404 Not Found error. Why is this and how do I go about rectifying this issue?
As a side note, I also started trying to have all http requests redirect to https. I added the following to the domain1.com htaccess file as I wanted all requests on both domains to redirect to https and I assumed this was necessary:
RewriteCond %{HTTPS} !on
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
Now this kind of works. All requests, whatever they are (with or without www for instance), redirect to https, and when I visit it in my browser I get a green the icon indicating it's secured with SSL. Again even with this the previous issue of the domain redirect still doesn't work. But I have another odd issue here.
If I type in my browser simply "domain1.com" (ie without https:// or www. or a combination of the two), it will show just "domain1.com" in the address bar but with the green icon and say it is secured. If however I type in "domain2.com" (again with no https:// or www etc.) it does the same thing except it states it is not secure, suggesting it requested http.
And yet if I type in www.domain2.com or http://domain2.com, that works and I get the secured icon. It is highly puzzling. It seems that the https redirect works on every request except for just "domain2.com" while any other variation (www.domain2.com, http://domain2.com etc) works fine. Any clues? I mean clearly I've done something wrong with the htaccess files but I don't know what, I got most of what I'd put in them from searching sites like Stackexchange, but personally I don't really know anything about them or how they work.
I think I have fixed my own problem here.
I corrected the main htaccess so the https redirect acts like this;
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteCond %{HTTPS} off
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
From what I can tell it's better to do it this way than the way I had it previously. This in itself didn't fix the problems. What fixed it for me is editing the domain2.com htaccess to look like this:
RewriteEngine on
#Force WWW if it isn't in the request
RewriteCond %{HTTP_HOST} !^www\. [NC,OR]
#Or include WWW even if it is in the request
RewriteCond %{HTTP_HOST} ^www\. [NC]
#Then Force it to use https
RewriteRule .* https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
#Defines this domain so main htaccess rules for subdomains work
RewriteCond %{HTTP_HOST} ^(.*)?domain2.com$ [NC]
#Proxy for Ghost
RewriteRule ^(.*)$ http://127.0.0.1:55555555/$1 [P,L]
Now everything works. All requests are redirected to https. All requests to the subdomain from the main domain fail with a 404. domain2.com now redirects to https://www.domain2.com or https://domain2.com so it is now always secured by SSL. I'm a novice at htaccess as is probably evident and I've no doubt some or all of this could have unnecessary elements removed or simplified so if anyone wants to correct my syntax so it's less messy I'd appreciate it.

htaccess redirect to a specific url on same domain (without looping)

I really hope you can help me out (it is driving me crazy).
I've tried dozens of setups and nothing seems to work, Googled myself dizzy and tried numerous different setups, but it all seems to result in a loop or a server error.
This is what needs to happen:
I have a site with multiple domains attached to it. What I need is that when someone visits the website via the "domain.co.uk"-domain, a redirect to the correct language parameters (among others) takes place.
To be very specific: when visiting via "www.domain.co.uk" the visitor must be redirected to "www.domain.co.uk?lang=en&noredir=1&currency=3"
I've made sure that the www is present with this:
RewriteCond %{HTTP_HOST} !^www.domain.co.uk$ [NC]
RewriteRule ^(.*)$ http://www.domain.co.uk/$1 [L,R=301]
The trouble is (I think) the redirect within the same domain without causing a loop.
I've tried stuff like this, but with no result:
RewriteCond %{HTTP_HOST} ^www.domain.co.uk$
RewriteRule ^$ http://www.domain.co.uk/?lang=en&noredir=1&currency=3 [L,R=301]
Hope you can help,
Cheers!
This will cause a loop:
RewriteCond %{HTTP_HOST} ^www.domain.co.uk$
RewriteRule ^$ http://www.domain.co.uk/?lang=en&noredir=1&currency=3 [L,R=301]
Because you're only checking the host header. Every time the redirect fires it will arrive back at the server with a host header of www.domain.co.uk and redirect again. You need to also check the query string and only redirect if it doesn't already match what you sent:
RewriteCond %{HTTP_HOST} ^www.domain.co.uk$
RewrteCond %{QUERY_STRING} !lang=en&noredir=1&currency=3
RewriteRule ^$ http://www.domain.co.uk/?lang=en&noredir=1&currency=3 [L,R=301]

Apache Mod_Rewrite needs to keep the Path but change the Domain

Background
I have a website that has several other alias domain names, in an effort to streamline and simplify I want all the domains to revert to the one domain name I now advertise -
Main name: www.explorerWorld.co.uk
Other names that load the same content but retain their own address:
www.exploreElsewhere.co.uk
www.exploitedexplodedexplorers.co.uk
what I have is that across the internet there are links in peoples blogs and elsewhere that go to specific pages on my site, but these will be under these different domains.
I have changed the domain Alises under cPanel and this works, for the base address only, but a domain for example www.exploreElsewhere.co.uk/trees.php does not redirect.
Question
I would like these pages to still work but to redirect to the main site -- www.explorerWorld.co.uk -- * but preserving their file path*
so: www.exploreElsewhere.co.uk/plants/trees.php gets seemlessly changed to www.explorerWorld.co.uk/plants/trees.php
My htaccess so far:
RewriteCond %{HTTP_HOST} !^exploreWorlds\.co\.uk$1 [NC]
RewriteRule ^(.*)$ http://www.exploreWorlds.co.uk/$1 [R=301,L]
But this seems to work in an endlessly repeating loop, How can I improve this htaccess ?
I have also looked here but this was not very helpful:
.htaccess change domain but keep path
I have found a solution to this problem was to use %{REQUEST_URI} which is the path given to the server.
(with a pointer from Arco444)
RewriteCond %{HTTP_HOST} !^(www\.)?exploreworlds\.co\.uk [NC]
RewriteRule ^(.*) http://www.exploreworlds.co.uk/%{REQUEST_URI} [R=301,L]
This successfully rewrites the domain part of the URL to force alias URL links to be redirected to my base website address + path
You have a mistake in your RewriteCond. Try
RewriteCond %{HTTP_HOST} !^www.exploreWorlds\.co\.uk$1 [NC]
RewriteRule ^(.*)$ http://www.exploreWorlds.co.uk/$1 [R=301,L]
instead, or remove the tilda from your original snippet

SSL redirection based on folder and domain

This seems like such an easy thing, yet I am having such trouble with it. I have a development server and a live server, I push, via git, from the dev server to live server once changes are tested etc...
I am using the following in my htaccess file:
RewriteCond %{HTTPS} !=on
RewriteRule ^(members/.*)$ https://live-domain.com/members/$1 [R=301,L]
Which works a treat on the live domain. But now when I go to dev-domain.com/members, it redirects to the https://live-domain.com.
What I need is it only to go to https if the members folder is called and it is live-comain.com. So I tried the following, and variants of:
RewriteCond %{HTTP_HOST} ^(.*\.)?live-domain\.com
RewriteCond %{HTTPS} !=on
RewriteRule ^(members/.*)$ https://live-domain.com/members/$1 [R=301,L]
But the above just times-out with an infinite loop error message on live-domain.com, and /members/members/members/members/members/ etc... in the url
Could someone please point me in the right direction so the https rewrite only occurs on live-domain.com.
Thanks
In case anyone else come across this question, my resolution is below.
There were various problems, the main one being I did not realise that Amazon AWS (Where my live site is) does not pass http or https info from the load balancer(where the SSL cert is) to the EC2 instance(where my script is).
You need to use HTTP:X-Forwarded-Proto to detect that. Full working htaccess below:
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteCond %{HTTP_HOST} ^(.*\.)?live-domain\.com
RewriteCond %{REQUEST_URI} members
RewriteRule ^(.*)$ https://live-domain.com/members/$1 [R,L]
The above is in the htaccess file within the members directory.
Hope it helps.

mod_rewrite remove www for all domains

I have multiple domains all pointing to the same website and depending on which domain you enter the website, will determine which categories will be selected.
For this to work I have to place any Mod_Rewrite code inside my
apache2/sites-available/primarydomain
file.
The website has the potential to host hundreds of domains so I need a system where I dont have to write a rule out for each domain eventuality.
I have seen this suggested online
RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC]
RewriteRule ^(.*)$ http://%1/$1 [R=301,L]
but it doesnt work for me.
Does any regex guru out there know if this is even achievable?
Heres hoping :-)
