How to use mod_rewrite in a subdomain's .htaccess? - apache

I have a domain (let the name be) mydomain.com.
I added a subdomain, sub.mydomain.com. (It's an other site, the two sites don't have anything to do with each other)
I have mapped the subdomain (with godaddy.com's tool) to /sub directory. It works well with static file paths, ex. http://sub.mydomain.com/js/script.js.php.
However, I would like to be able to use the rewrite module to get http://sub.mydomain.com/js/script.js
My .htaccess files:
.htaccess in the root directory:
RewriteEngine On
RewriteCond %{HTTP_HOST} ^sub.mydomain.com$
RewriteRule ^.*$ http://mydomain.com/sub%{REQUEST_URI} [L,P]
.htaccess in the /sub directory:
RewriteEngine on
RewriteRule ^js/script\.js$ js/script.js.php [L]
(I tried adding RewriteBase /sub/, I didn't succeed).
It seems as if Apache didn't notice the /sub's .htaccess
How can I get the rewrite work on the subdomain's paths?

SOLVED!
After a long, exhausting debugging and googling I found an Apache setting that made the trouble:
I added Options -MultiViews and voilá, it works!
/////////////////////////////////////////////
Now my configuration:
-no .htaccess in the root.
-.htaccess in the root/sub:
DirectoryIndex site/index.php
Options -MultiViews
RewriteEngine on
RewriteRule ^site/js/script.js$ /site/js/script.js.php [L]

How do I write a mod_rewrite so that it doesn't affect a subdomain that is in a subfolder

I have a site where the frontend is on the main domain and the backend is on a subdomain whose document root is a subfolder of the main domain's document root.
I have added this:
<IfModule mod_negotiation.c>
Options -MultiViews
</IfModule>
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.html$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.html [L]
</IfModule>
to the .htaccess file for the main domain because it was giving a 404 error for refreshes and direct access. The problem is that adding that config results in a 500 error on my backend. How can I solve this?
You shouldn't necessarily need to do anything with regards to the subdomain, depending on the type of requests you are making (which you've not stated).
However, you can disable mod_rewrite for the subdomain by creating an additional .htaccess file in the root of the subdomain (ie. in the subfolder off the main domain's document root) and place the following:
# /subfolder/.htaccess (subdomain)
RewriteEngine Off
.htaccess files are inherited along the filesystem path, so the .htaccess file in the root of the main domain will certainly be processed when accessing the subdomain, except that the conditions (RewriteCond directives) should already exclude any requests for actual files/directories.
So it turns out I only needed to add one line to exclude the affected subdomain.
RewriteCond %{HTTP_HOST} !example\. [NC]
That did the trick.

AllowOverride and RewriteCond/RewriteRule interactions

I'm trying to set up a site running on Apache 2.4.16 to redirect all www URLs to non-www URLs. I'm using HTML5 Boilerplate's Apache configs to do this (as well as everything else they provide).
https://github.com/h5bp/server-configs-apache/blob/master/dist/.htaccess
This happens on line 380, seen below:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTPS} !=on
RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC]
RewriteRule ^ %{ENV:PROTO}://%1%{REQUEST_URI} [R=301,L]
</IfModule>
I'm using Include to add the whole file to my vhost config for the site, as well as an AllowOverride All for another .htaccess file at my doc root (same one that comes with Laravel 5):
production.vhost.conf (relevant part)
<Directory /var/www/hostname/production>
AllowOverride All
# Include H5BP server configs
Include server-configs-apache/dist/.htaccess
</Directory>
.htaccess (at doc root)
<IfModule mod_rewrite.c>
<IfModule mod_negotiation.c>
Options -MultiViews
</IfModule>
RewriteEngine On
# Redirect Trailing Slashes If Not A Folder...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)/$ /$1 [L,R=301]
# Handle Front Controller...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]
</IfModule>
Now, almost everything from H5BP's .htaccess was working, except for the redirect from www to non-www. After poking around I noticed that the redirect was only working when I'd remove AllowOverride All from the <Directory> block in the vhost. So the doc root .htaccess was somehow overriding the rewrite conditions.
I've actually already fixed my initial issue by moving the doc root .htaccess contents into the vhost file and removing the AllowOverride, but I'm more curious as to why this was happening; more specifically how AllowOverride interacts with RewriteCond and RewriteRule.
My hunch is that the .htaccess in my doc root was overriding the www to non-www redirect, but I'm not sure why that one specifically. For example, the http -> https redirect worked without issue (line 352 of H5BP, uncommented out in mine), it seemed to be just that one redirect. I didnt even think that those rules could be overridden since RewriteCond/RewriteRules feel unique to me.
If there are any, what are the rules that determine how an .htaccess can override a rewrite rule?

Conditions and rules don't dictate how .htaccess works. AllowOverride is what allows .htaccess usage. If you have AllowOverride All then .htaccess is allowed, if you have AllowOverride None, then it's not and it will be ignored. In 2.4 None is the default.
.htaccess is per directory so it will take precedence if it's located in a directory that has rules applied as long as .htaccess file usage is allowed there. Which is confgiured in the server config in VirtualHost or Directory directives.
Also using an include for .htaccess in a vhost is a very bad configuration. If you have access to the vhost file or the config, you should create another config and include it with the .htaccess contents.
You should not be using .htaccess files at all actually with access to the server config. See this apache recommendation on not using .htaccess.

.htaccess redirect sub directory access attempts back to root

I wish to protect folders such as /css and /js from listing directory contents to snoopers. Perhaps I could do this via PHP, but I need to use .htaccess.
Desired:
Anyone browsing to http://example.com/css should not see a listing of files, but is immediately redirected back to http://example.com.
I have tried several variations on the following, but cannot seem to get it right:
.htaccess inside each private folder:
RewriteEngine On
Redirect 301 /. http://example.com
or, in the webroot:
RewriteEngine On
RewriteBase /
RewriteRule /(.*)$ /$1 [L,NC,R]
Note: I already have an .htaccess file in the webroot, which any additional mod_rewrite commands would need to accomodate:
RewriteEngine On
RewriteBase /
RewriteRule ^dev/(.*)$ /$1 [L,NC,R]
RewriteRule ^/(.*)$ /dev/$1 [L,NC]
You can create /css/.htacces with this line:
ErrorDocument 403 http://example.com/
Options -Indexes
Do same in /js/.htaccess file.

htaccess rewriterule to send a file to another file in the same directory

I have a directory that contains an index.php and an index.html file, both being published from a CMS. There's a specific IP address that will attempt to access index.html, but should instead be shown index.php in the same directory. All other traffic should act as normal.
I've been working with some variations of this code:
RewriteEngine On
RewriteCond %{REMOTE_HOST} ^123\.456\.789\.10
RewriteRule ^index\.(htm|html?)$ index.php [NC,R=301,L]
This does do the redirect, but of course it goes to the root of the site rather than staying in the same directory. It's somewhat unclear what the directory path will be in all cases, so I'd like to tell Apache to stay in the same directory it's in.
Is this possible?
Thanks,
Jonathan
If you want to have this rule for IP: 123.456.789.10 then you shouldn't have this IP with
negation like: RewriteCond %{REMOTE_HOST} !
Try this code:
Options +FollowSymLinks -MultiViews
# Turn mod_rewrite on
RewriteEngine On
RewriteBase /subdir/
RewriteCond %{REMOTE_HOST} ^123\.456\.789\.10$
RewriteRule ^index\.html?$ index.php [NC,R=302,L]

Using .htaccess file to redirect to a subdomain

In my root folder, I have a home directory. I'd like all requests for mydomain.com or www.mydomain.com to be forwarded to home.mydomain.com. In my cPanel, I have already set up the sub-domain home.mydomain.com to point to mydomain.com/home.
Here's what I currently have in my .htaccess file:
RewriteEngine On
Options +SymLinksIfOwnerMatch
RewriteRule ^(.*)$ \/home\/$1 [L]
This successfully forwards mydomain.com and www.mydomain.com to mydomain.com/home or www.mydomain.com/home, respectively. But home.mydomain.com/filename gives me an internal server error, instead of serving the file at mydomain.com/home/filename.
I'm not sure I understand the exact requirements, but it seems you want to rewrite all (www.)mydomain.com requests to the /home directory while your subdomain home.mydomain.com already points to that directory and thus should be exempt from that rewrite directive. If for some reason (www.)mydomain.com can't be set up to point to /home as well, you'd need a Rewrite Condition, something like
RewriteEngine On
Options +SymLinksIfOwnerMatch
RewriteCond %{HTTP_HOST} ^(www\.)?mydomain\.com$ [NC]
RewriteRule ^(.*)$ /home/$1 [L]
I also removed the backslashes which should not be needed. You can use the htaccess tester to check rewrite rules easily online.
