On my new site I want to have dynamic subdomains. I'm trying to make it so that the subdomains use the same web root as the main domain, all under a single CodeIgniter installation. For example, subdomain.example.com would lead to example.com/subdomain, which is actually example.com/index.php/subdomain.
I've already the DNS set up but I'm getting caught up on the .htaccess.
VirtualDocumentRoot /var/www/crashworks/public/%-3+ Is the line from my sites-available configuration just for completeness. This might also be the source of the issue.
The effect of the linked htaccess is that when navigating to any subdomain, it gets caught up in an infinite loop. (Error log after one request.) It's the same effect for www., which should just resolve to the main domain.
Did you try
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.example\.com$ [NC]
RewriteCond %{HTTP_HOST} ^([a-z0-9]+)\.example\.com$ [NC]
RewriteRule ^/(.*)$ index.php?url=%1&path=$1 [L,QSA]
Or something like this?

I'm trying to set up a test site but having real trouble getting .htaccess to redirect properly.
I want the contents of www.example.com/test to show when a user types in test.example.com. My rewrite rules allow me to use test.example.com in the address bar, but it's actually showing me the content of the root (www.example.com), not the test subfolder.
I'm not an .htaccess guru by any stretch, but I've been using Stack Overflow for 5 years and this is the first time I've been stumped enough to ask a question! Your collective wisdom is appreciated.
Here's the relevant part of my .htaccess code:
RewriteEngine On
# Rewrite for http cases
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [L]
# Rewrite for no www cases
RewriteCond %{HTTP_HOST} !www\.example\.com [NC]
#redirect for test subdomain
RewriteCond %{HTTP_HOST} !^test\.example\.com$ [NC]
RewriteRule ^(.*)$ https://www.example.com/$1 [R=301,L]
# redirect to correct for old subfolder usage
RewriteRule ^oldsubfolder/$ https://www.example.com/ [L,R=301]
I want the contents of www.example.com/test to show when a user types in test.site.com.
I assume you just have one domain and test.site.com should really be test.example.com (which would seem to be consistent with the rest of your question)?
In the code you've posted, there's nothing that really attempts to do this redirect? In the code you've posted, a request for test.example.com would not be redirected - so if it is then you may be seeing a cached response. Clear your browser cache.
You would need something like:
RewriteCond %{HTTP_HOST} ^(?:www\.)?(test)\.example\.com [NC]
RewriteRule (.*) http://www.example.com/%1/$1 [R,L]
The (?:www\.)? part simply catches an optional www subdomain of the subdomain! Depending on how this subdomain was created, both test.example.com and www.test.example.com might be accessible. (Although I suspect your SSL cert probably doesn't allow this anyway?)
%1 is a backreference to the captured group in the CondPattern (ie. test) and $1 is a backreference to the captured RewriteRule pattern. Capturing the subdomain (eg. "test") just avoids repetition, but also allows for more than one subdomain to be handled by the same rule.
This is also a temporary (302) redirect. Change this to a 301 only when you are sure it's working (if that is the intention). 301s are cached by default, so can make testing problematic.
Clear your browser cache before testing.
# Rewrite for no www cases
RewriteCond %{HTTP_HOST} !www\.example\.com [NC]
#redirect for test subdomain
RewriteCond %{HTTP_HOST} !^test\.example\.com$ [NC]
RewriteRule ^(.*)$ https://www.example.com/$1 [R=301,L]
The comment in the middle of this block would seem to be misleading (it doesn't "redirect for test subdomain"). The whole block just redirects to www, excluding the test subdomain. The other code then redirects the subdomain.
UPDATE:
I was hoping it would continue to show test.example.com in the address bar
Yes, this is possible. Providing test.example.com and www.example.com point to the same filesystem then you can simply rewrite the request without actually changing the host. For this example, I'll assume test.example.com and www.example.com point to the same document root.
Change the above redirect to the following rewrite:
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteCond %{HTTP_HOST} ^(?:www\.)?(test)\.example\.com [NC]
RewriteRule (.*) /%1/$1 [L]
The request now stays on test.example.com and will serve content from test.example.com/test (although this is hidden from the user) since test.example.com and www.example.com are really the same thing.
The check against REDIRECT_STATUS ensures we are only processing the intial request and not the rewritten request, thus avoiding a rewrite loop. REDIRECT_STATUS is empty on the initial request and set to 200 after the first successful rewrite.
However, if test.example.com points somewhere entirely different then you'll need to implement a reverse proxy and "proxy" the request to www.example.com in order to "hide" this from the user.
I have two webs on two different domains. One is on domain.com and the other web is on domain.es.
I am shutting down the web on domain.es but first I have to redirect every request to domain.es to domain.com. This is easy and I had already done it with RewriteCond & RewriteRule, like this:
www.domain.es/ -- redirects to --> www.domain.com/
But I am having a problem now. I also need to redirect one specific page from domain.es to domain.com like this:
www.domain.es/a_page/ -- redirects to --> www.domain.com/another_page/
I am having problems when redirecting with both rules, as when apache detects a request to www.domain.es/a_page it goes to www.domain.com/ and not to the specific page I need.
I have this in my virtualhost:
RewriteCond %{HTTP_HOST} ^domain.es/a_page/
RewriteRule ^(.*)& http://www.domain.com/another_page/ [R=301,L]
RewriteCond %{HTTP_HOST} ^domain.es/
RewriteRule ^(.*)& http://www.domain.com/ [R=301,L]
I've got the [L] flag so apache would stop processing rules, but this is not working.
Any help would be appreciated.
RewriteCond %{HTTP_HOST} ^domain.es/a_page/
The line above is never going to match anything - you're asking if the host is equal to domain.es/a_page/, which is a host as well as a path. You need to test against only the hostname, and then redirect based on the path, e.g.
RewriteCond %{HTTP_HOST} ^domain\.es
RewriteRule ^a_page/ http://www.domain.com/another_page/ [R=301,L]
Does anyone know a way to do a permanent redirect from a.example.com to b.example.com? I have other subdomains that need to remain as they are though. so:
first.example.com -> second.example.com
third.example.com is fine
fourth.example.com is fine
I want to do this in the <VirtualHost> block rather than an .htaccess to avoid having to redeploy again.
Any thoughts would be appreciated, thanks
Add the following RewriteRule to your VirtualHost
RewriteEngine On
RewriteCond %{HTTP_HOST} ^first.example.com$
RewriteRule ^ http://second.example.com [R=301,L]
If you wanted to redirect first.example.com/some/url to second.example.com/some/url:
RewriteEngine On
RewriteCond %{HTTP_HOST} ^first.example.com$
RewriteRule /(.*) http://second.example.com/$1 [R=301,L]
Recommend you use [R=302] whilst testing the rules to avoid problems with 301s getting cached by your browser.
I've read a lot of questions and answers about this on here but none that seem to solve my specific problem.
I want to redirect any subdomain to the subdirectory to match.
So: x.domain.com would go to domain.com/x, and y.domain.com would go to domain.com/y - But I want to do this without the URL in the address bar changing.
Here's what I have so far:
Options +FollowSymLinks
RewriteEngine on
RewriteBase /
RewriteCond %{HTTP_HOST} !^(www)\. [NC]
RewriteCond %{HTTP_HOST} ^(.*)\.domain\.com [NC]
RewriteRule ^ /%1 [P,L]
But this takes me to a website redirect loop, with an incorrect address in the URL bar where the subdomain still exists.
For example, x.domain.com takes me to x.domain.com/x and I get a redirect loop error.
I'd be grateful if anyone can point me in the right direction! Nothing I change seems to work...
First of all, make sure that the vhost in the apache configuration is properly configured and all subdomains of domain.com are in the same host configuration (wildcard):
<VirtualHost *:80>
ServerName domain.com
ServerAlias *.domain.com
...
You can get the redirect working with the following htaccess configuration:
RewriteEngine on
RewriteCond %{HTTP_HOST} ^(.*)\.domain\.com
RewriteRule ^(.*)$ http://domain.com/%1/$1 [L,NC,QSA]
Now, if you open asd.domain.com it should redirect you to domain.com/asd.
You will still have the problem, that the redirect is visible in the URL address bar. In order to prevent this, enable mod_proxy (and load the submodules) on your server and exchange the "L" flag with the "P" flag:
RewriteEngine on
RewriteCond %{HTTP_HOST} ^(.*)\.domain\.com
RewriteRule ^(.*)$ http://domain.com/%1/$1 [P,NC,QSA]
If this doesn't work, viewing the vhost configuration and the content of error.log on subdomain calling will be helpful!
References:
.htaccess rewrite subdomain to directory
http://httpd.apache.org/docs/2.2/mod/mod_proxy.html
http://httpd.apache.org/docs/2.2/rewrite/flags.html#flag_p
This can be achieved in .htaccess without mod_proxy provided your server is configured to allow wildcard subdomains. (I achieved that in JustHost by creating a subomain manually named *). Add this to your .htaccess file:
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.website\.com$
RewriteCond %{HTTP_HOST} ^(\w+)\.website\.com$
RewriteCond %{REQUEST_URI}:%1 !^/([^/]+)/([^:]*):\1
RewriteRule ^(.*)$ /%1/$1 [QSA]
I named the subdirectories under $_SERVER['DOCUMENT_ROOT'] match with my subdomains like so:
/
var/
www/
html/
.htaccess
subdomain1.domain.com/
subdomain2.domain.com/
subdomain3.domain.com/
Where /var/www/html stand as 'DOCUMENT_ROOT'. Then put following code in the .htaccess file:
RewriteEngine on
RewriteCond %{REQUEST_URI} !^/%{HTTP_HOST}/
RewriteRule (.*) /%{HTTP_HOST}/$1 [L]
It works as redirect wildcard subdomains to subdirectories, without changing URL in address bar.
Beside of vhost, you may also put the subdirectories outside root and access it using alias as described here. Then put the same .htaccess code in that location.
I have two different sites on same domain for example:
First site in the root directory http://example.com/
Second site in subfolder http://example.com/site2/
Each site have his own .htaccess
When i enter to second site (http://example.com/site2/), in log of mod_rewrite i see that apache trying to execute .htaccess of first site (http://example.com/).
So, the question is how to prevent this?
Thanks

inherit
This forces the current configuration to inherit the configuration of
the parent. In per-virtual-server context, this means that the maps,
conditions and rules of the main server are inherited. In
per-directory context this means that conditions and rules of the
parent directory's .htaccess configuration are inherited.
Rules inherited from the parent scope are applied after rules specified in the child scope.
While you can not stop the execution of the .htaccess in http://example.com
You CAN place another .htaccess in http://example.com/site2/ and any rule created here that overrides the rules in the .htaccess of the parent folder will be executed here but not in the parent folder.
For example, I recently had a case where I was rewriting any non-www version of my main site, which we'll call example.com to its www equivalent: www.example.com
The problem this caused is anyone going to my second site, which we'll call site2.com would actually redirect the user to www.example.com/site2.com/ even if the user enters site2.com OR www.site2.com OR http://www.site2.com in their browser's address input
What I had to do to fix it is makes changes in 2 .htaccess files, first in the root http://www.example.com then in a separate .htaccess located in http://www.example.com/site2.com/
1) http://www.example.com .htaccess:
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.example\.com$ [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [R=301,L]
2) http://www.site2.com (http://www.example.com/site2.com/) .htaccess(this also forces the www version of site2.com):
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.site2\.com$ [NC]
RewriteRule ^(.*)$ http://www.site2.com/$1 [R=301,L]
RewriteCond %{HTTP_HOST} ^site2\.example\.com$ [OR]
RewriteCond %{HTTP_HOST} ^www\.example\.com/site2\.com$ [OR]
RewriteCond %{HTTP_HOST} ^www\.site2\.example\.com$
RewriteRule ^/?$ "http\:\/\/www\.site2\.com\/" [R=301,L]
Feel free to rip apart my regex, I am by no means a regex master. I also realize that this can creates 2 or maybe more extra redirects but this is the only way I could get this to work, without reassigning my DocumentRoot through through the host...which is probably a better option if your host can do it, mine would/could not...
