We are currently migrating from one domain to another, I need to write a rewrite rule that will redirect all websites from the old domain to the new one.
I can match if the browser try to access the old domain :
RewriteCond "%{HTTP_HOST}" "^(.*).old.com$" [NC]
Now I need the rewrite rule that can extract the host before ".old.com" to create the new URL with "xx.new.com". It seems to me that a RewriteRule only contains the path of the page being accessed and not the full URL that would contain the host part.
I would like to do something like this :
RewriteRule "^https:\/\/(.*)\.old\.com(.*)$" "https://$1.new.com/$2" [R=301,L]
How can this be achieved?
Any help would be greatly appreciated.
Your condition is good but your rewrite rule is wrong: the regex pattern will be matched against the part of the URL after the hostname and port, and before the query string, so there is no hostname there.
Still, your substitution can back-reference to the pattern matched in RewriteCond:
RewriteCond "%{HTTP_HOST}" "^(.*).old.com$" [NC]
RewriteRule ^ "https://%1.new.com%{REQUEST_URI}" [R=301,L]

In my application when the url hit like
http://monohar.opens.com
it should redirect to
http://xx.xxx.xx/folder/manohar
Using htaccess rewrite rule , here domain 'monohar' will be dynamic domain name , could be changed to any thing dynamically but url always ends with 'opens.co'
Please suggest me how to achieve this
You can use this rule in your site root .htaccess or Apache config:
RewriteEngine On
RewriteCond %{HTTP_HOST} ^(.+)\.opens\.com$ [NC]
RewriteRule ^ http://xx.xx.xx/folder/%1%{REQUEST_URI} [L,NE,R=301]
%1 is back-reference of substring before first DOT in HTTP_HOST variable.
After a couple of hours of fighting, I manage to generate an htacces file to redirect all my old URLs to the URLs of my new site (same domain). I am using the following rules to manage my subfolders redirects (my new site has only a couple of pages):
RewriteRule ^es/empresa/terminos-y-condiciones.html$ http://domain/terminos-y-condiciones.html [L]
RewriteRule ^es/servicios/registro-de-dominios/.*$ http://domain/dominios.html [R=301,NC,L]
RewriteRule ^es/empresa/.*$ http://domain/nosotros.html [R=301,NC,L]
RewriteRule ^es/component/.*$ http://domain/contacto.html [R=301,NC,L]
RewriteRule ^es(/.*)?$ / [R=301,NC,L]
The problem is that when I try to access to some pages like domain.com/empresa/testimonios-de-clientesc69a.html?lang=es it redirects me to domain/?lang=es , that is my domain+the parameter after ".html".
So, I was wondering if there was a way to eliminate this parameter and redirect only to www.domain.com ?
Thanks in advance!
To truncate a query string add a '?' sign to the end of target URLs like this:
RewriteRule ^es/empresa/.*$ http://domain/nosotros.html? [R=301,NC,L]
On Apache 2.4 or later you can use the QSD flag to discard the query string (see documentation):
When the requested URI contains a query string, and the target URI
does not, the default behavior of RewriteRule is to copy that query
string to the target URI. Using the [QSD] flag causes the query string
to be discarded.
So it would look like
RewriteRule ^es/empresa/.*$ http://domain/nosotros.html [R=301,NC,L,QSD]
My goal is to redirect an entire domain to another. Every URL of the old domain shall redirect to the root URL of the new domain.
To achieve this I'am doing:
redirect 301 / http://www.google.de/
Problem is that when I test it on http://localhost/randomPath then it redirects to http://www.google.de/randomPath, but not to the root URL of google.de.
Does anyone know how to solve this?
Use mod_rewrite for finer control on rules like matching Host name etc.:
RewriteEngine On
RewriteCond %{HTTP_HOST} ^(www\.)?olddomain\.com$ [NC]
RewriteRule ^ http://www.google.de/? [L,R]
? in the end of target URI will strip off any existing query string.
Got a question about using mod_rewrite to redirect specific subdomains to use another domain. I am looking for the shortest possible way to do this without the need to create a separate rewrite rule for each of my domain names. I will be adding many new domain names (roughly 20-30 domains total).
So let's say my main domain name is example.com and I want to use that domain name for everything. So if any of my other domains are used, they will automatically be redirected to the main domain, preserving the subdomain prefix and the URL path.
Example:
test.example.org => test.example.com
test2.example.co.uk => test2.example.com
test3.example.net/hello/world.php => test3.example.com/hello/world.php
RewriteEngine on
RewriteCond %{HTTP_HOST} ^(.*)\.([a-zA-Z]+)\.(.*)$ [NC]
RewriteRule ^(.*)$ http://%1\.example.com/$1 [R=301,L]
I am unsure if the above will work correctly or if it is proper syntax. But basically, I would like to have it match the subdomain prefix, then any domain name, and any TLD (.org, .info, .biz, .co.uk, .net, etc.). I would assume it would need to make sure that it is not the correct main domain (example.com) first to prevent a infinite redirect loop.
Also, is there a possibility to check if HTTPS is ON or OFF and set the redirect correctly? If not, I can always have HTTPS set to ON.
Sorry for this confusion, although I want to make sure I get this right the first time without needing to program each and every one of the domains into the .htaccess.
Thanks! :)
(.*) is greedy so you don't want to use that, and I assume that you don't want to recreate an infinite loop.
RewriteEngine on
RewriteCond %{HTTPS}s ^..(s?)
RewriteRule ^ - [E=PROTO:http%1]
RewriteCond %{HTTP_HOST} !^\w+\.example\.com$ [NC]
RewriteCond %{HTTP_HOST} ^(\w+)\.\w+\..+ [NC]
RewriteRule ^/?(.*) %{ENV:PROTO}://%1.example.com/$1 [R=301,L]
That rule will not work because it will redirect any host ending with example.com back to example.com and you'll get a redirect loop. You need to change the regex to look like this, to match anything that doesn't end with .com:
RewriteCond %{HTTP_HOST} ^([^\.]+)\.?([a-zA-Z]+)\.(?:(?!com).)*$ [NC]
I need a mod_rewrite rule to redirect url depending on the hostname they are comming from.
The situation:
We have multiple domains pointing to a same webspace and we need to restrict what the specific host can see/download.
domainname.com/images/logo.jpg and /www.domainname.com/images/logo.jpg should transform into domainname.com/domainname_com/images/logo.jpg
So basically I need a rule/function that replaces the dots in the %{HTTP_HOST} with _ and removes/replaces the www subdomain.
Is there any way to do this with mod_rewrite?
Try these rules:
RewriteCond %{ENV:DOMAIN_DIR} ^$
RewriteCond %{HTTP_HOST} ^(www\.)?(.+)
RewriteRule ^images/.+ - [E=DOMAIN_DIR:%2]
RewriteCond %{ENV:DOMAIN_DIR} ^([^.]*)\.(.+)
RewriteRule ^images/.+ - [E=DOMAIN_DIR:%1_%2,N]
RewriteCond %{ENV:DOMAIN_DIR} ^[^.]+$
RewriteRule ^images/.+ %{ENV:DOMAIN_DIR}/$0 [L]
The first rule will take the host and store it without www. in the environment variable DOMAIN_DIR. The second rule will replace one dot at a time; the N flag allows to restart the rewriting process without incrementing the internal recursion counter. Finally, the third rule will rewrite the request to the corresponding directory.
