mod_rewrite, subdomains and htaccess in CodeIgniter - .htaccess

Right now i'm working on a webshop project in codeigniter.
In the end there will be multiple webshops on subdomains, and a frontpage on the main domain.
It's supposed to be all dynamic so that the webshops get their own subdomains.
The shop information is in the database. Lets say I have a mysql table which contains info like this:
webshop: Bobs shop
webshop_subdomain: bobsshop
And so on.
Now in a .htaccess file I want to make a rewrite rule so that bobsshop.mydomain.com will be rewritten to mydomain.com/bobsshop/ since i'm working in Codeigniter with controllers.
You should bear in mind that the index.php also has to be rewritten out and there should also be the possibility to make subpages like bobsshop.mydomain.com/contact/
I will make a php script which will check if the subdomain exists in the database and if it doesn't exist then the visitor will see a 404.
My DNS setup looks like this ATM:
mydomain.com xxx.xxx.xxx.xxx
*.mydomain.com xxx.xxx.xxx.xxx
Where xxx.xxx.xxx.xxx is my server IP.
I've really never worked with htaccess / mod_rewrite before.
Can it be done? And are there anyone who can help me make this?
Sorry for my English. I hope you understand what I'm trying to do.
Thanks in advance

RewriteEngine on
RewriteCond $1 !^(index\.php|resources|robots\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{HTTP_HOST} ^((?!www\.)(?!mydomain\.com)[^\.]+)\.
RewriteRule ^(.*)$ http://www.mydomain.com/index.php?/%1/$1 [L]
Input URL - http://adasd.mydomain.com/test
1 RewriteCond %{HTTP_HOST} ^((?!www\.)(?!mydomain\.com)[^\.]+)\.
This condition was met
2 RewriteRule ^(.*)$ http://www.mydomain.com/index.php?/%1/$1 [L]
This rule was met, the new url is http://www.mydomain.com/index.php?/adasd/test
The tests are stopped, using a different host will cause a redirect
Output URL - http://www.mydomain.com/index.php?/adasd/test
You can then remove the index.php from the URL by
Open config.php from system/application/config directory and replace
$config['index_page'] = "index.php" with $config['index_page'] = ""
Implementing the above .htaccess file
In some case the default setting for uri_protocol does not work properly. To solve this problem just replace $config['uri_protocol'] = "AUTO" with $config['uri_protocol'] = "REQUEST_URI" in system/application/config/config.php

Hiding Directory in URL with htaccess is not working

I have website1.com setup so that when users visit website1.com they get redirected via a meta tag in an index.html to website1.com/directory
Then they use the website and go to links such as website1.com/directory/index.html or what ever. I am trying to hide the "directory" in the link so that users only see website1.com/index.html
I have place the htaccess which is to rewrite the url to website1.com/index.html at website1.com/directory/.htaccess
I am not doing anything else special and this should be an easy task. My current exact htaccess is as follows:
RewriteEngine On
RewriteCondition %{REQUEST_URI} !^directory/
RewriteRule ^(.*)$ directory/$1 [L]
Should be easy right..... All I get is a 404
In my server I have Mod_Rewrite & mod security and suspect one of them is causing this not to work but can't imagine why. Am I missing something here?
Your rule is incorrect since %{REQUEST_URI} variable has starting /
You need to place this in document root
Use this code in document root .htaccess:
RewriteEngine On
RewriteCondition %{REQUEST_URI} !^/directory/
RewriteRule ^(.*)$ /directory/$1 [L]

htaccess subdomain rewrite without a redirect

Using htaccess Rewrite, I want my url http://*.phoneataxi.com/ (where * is a wildcard, excluding 'www') to show in the address bar as is but get information from http://*.phoneataxi.com/test.php?c=*.
I have tried so many different things but nothing is doing exactly what I need. Most examples are redirecting the subdomain to the '/test.php' file in the address bar which I don't want to do.
I'm trying not to have to create individial subdomains and subdomain folders within my webroot.
Ideas?
I use this htaccess file to make Apache act as a proxy for another host:
IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{HTTP_HOST} ^ghost\.pileborg\.se$
RewriteRule (.*) http://vps.pileborg.se/ghost/$1 [P]
</IfModule>
It causes all access to http://ghost.pileborg.se/ to be "redirected" to http://vps.pileborg.se/ghost/.
UPDATE (2020)
Some of the answers regarding this topic is very old and no longer work as expected.
After searching for hours on something that actually works, this is what I came up with; edit as you see fit:
RewriteEngine on
RewriteBase /
RewriteCond %{HTTP_HOST} ([a-z0-9]+)\.
RewriteRule ^(.*)$ - [E=BASE:%1]
RewriteCond %{DOCUMENT_ROOT}/%{ENV:BASE}/index.php -f
RewriteRule ^(.*)$ %{ENV:BASE}/index.php [L,NC,QSA]
RewriteCond %{DOCUMENT_ROOT}/%{ENV:BASE}/index.html -f
RewriteRule ^(.*)$ %{ENV:BASE}/index.html [L,NC,QSA]
Breakdown
Make sure that the rewrite module is installed and enabled on your host
first we turn the rewrite engine on and set the path-base
then isolate the subdomain - any letters/numbers before the first dot
set a variable in this runtime environment that contains the subdomain
check if the subdomain folder and index-file exists
if it does exist -then use that file as the request-handler (no redirect)
if it does not exist then the request carries on normally
Flags
The flags used here are explained here, but the ones used above are quite simple:
[L] Last rule, ignore the rest
[NC] No Case, no uppercase/lowercase restrictions
[QSA] I remember this as "Query String Attach" :D

htaccess to add directory after domain name?

How can I use htaccess to always ADD a directory immediately after the domain name?
So for example, change requests for
http://domain.com/path-to/file.php
to
http://domain.com/added-directory/path-to/file.php
The context here is that i am migrating a site to a new server, and the domain name is not yet pointed to the new server. But the hosting company provides me with a "temporary url" based on the Shared IP and my account username, so http://216.172.172.211/~myusername/ , but all the paths in all the html are doc-root relative, like /images/logo.png, which translates to http://216.172.172.211/images/logo.png which is wrong. I need it to be http://216.172.172.211/~myusername/images/logo.png .
try adding these rules to the htaccess file in your document root:
RewriteEngine On
RewriteCond %{REQUEST_URI} !^/~myusername
RewriteRule ^(.*)$ /~myusername/$1 [L]
If you want to redirect so that URLs show the ~myusername part in the URL address bar, add an R flag to the square brackets:
RewriteRule ^(.*)$ /~myusername/$1 [L,R=301]
This worked for me perfectly
RewriteEngine on
RewriteCond %{REQUEST_URI} !^/~gye
RewriteRule ^(.*)$ https://%{HTTP_HOST}/gye/$1 [R=301,L]
If an URL comes without the /XYZ
Add https:// at the beginning and /gye/ after the domain.

htaccess command to prevent master site access via subdirectory?

I have hosting setup with a master domain (mapped to the web root) and then a number of addon domains (each with their own folder within the web root). At the moment you can visit www.masterdomain.com/addondomainsubdir and reach the same page as you would if you visited www.addondomain.com (which maps to /public_html/addondomainsubdir). I want to prevent this so if you visit www.masterdomain.com/addondomainsubdir then it will do a 301 redirect to www.addondomain.com. The new addondomain.com site is a single page site so it does not have to map any additional pages.
Adding rules to the htaccess file in the web root does notaffect anything as the subdir exists which is wierd as i thought the htaccess command should work even if there is a matching subdir (i've tried the following which works when there's no matching subdir):
RewriteRule ^addondomainsubdir?$ http://www.addondomain.com [NC,R=301,L]
Logically given it's reaching this directory I figure i need to add a command within the htaccess file in the addondomainsubdir directory however nothing appears to have any effect (i've got various other rules setup and they work fine).
I would be massively grateful if anyone explain the best way to rectify this?
Thanks so much for your help,
Dave
I know this is an old post, but it has never been successfully answered. So for all of you finding this via search, this should do what the OP is asking.
Add this line to your .htaccess file:
redirect permanent /addondomainsubdir/ http://www.addondomain.com
Try these rules in your .htaccess:
Options +FollowSymlinks -MultiViews
RewriteEngine on
# for http
RewriteCond %{HTTP_HOST} ^(www\.)?masterdomain\.com$ [NC]
RewriteCond %{SERVER_PORT} =80
RewriteRule ^([^/]+)/?$ http://www.$1.com/ [R=301,L]
# for https
RewriteCond %{HTTP_HOST} ^(www\.)?masterdomain\.com$ [NC]
RewriteCond %{SERVER_PORT} =443
RewriteRule ^([^/]+)/?$ https://www.$1.com/ [R=301,L]
Instead of putting a rule in your main .htaccess, I would make make a .htaccess for each add-on domain, putting each one in the respective subdirectory.
RewriteEngine on
RewriteCond %{HTTP_HOST} masterdomain\.com$ [NC]
RewriteRule ^addondomainsubdir(.*)$ http://www.addondomain.com/$1 [R=301,L]

.htaccess subdomains redirect is not working

Ok, now I am lost.
I am trying to do a simple .htaccess redirect of subdomains to a specific folder on the server, meaning all
subdomain.mywebsite.com
will go to
www.mywebsite.com/s_subdomain
But for some reasons this doesn't work.
I have tried a lot of settings in .htaccess but for no good. Now in my .htaccess I have:
RewriteEngine on
Options +FollowSymLinks
Options +SymlinksIfOwnerMatch
RewriteCond %{HTTP_HOST} !^(www|ftp|mail)\.mywebsite\.com
RewriteCond %{HTTP_HOST} ^([^.]+)\.mywebsite\.com
RewriteRule (.*) /s_%1/$1 [L]
Are there any other settings, or is somethig I have missed?
PS. - I don't have access to http.conf. I have to do it using only .htaccess
Thanks!
This is just a "plain" rewrite (the browser won't see it). To redirect, add the R flag to your RewriteRule.
RewriteRule (.*) /s_%1/$1 [L,R]
The rest seems right, although I haven't tested it. For debugging you could consider RewriteLog, see http://httpd.apache.org/docs/2.0/mod/mod_rewrite.html#rewritelog
So, neither solution does work? Try something simple then.
RewriteEngine on
RewriteCond ${SERVER_NAME} ^(subdomain)\.yoursite\.com$ [nc]
RewriteRule ^(.*)$ http://www.yoursite.com/s_%1/$1 [L,R]
To test if your subdomain is handled correctly, create random.html file, place it where it should be read from, and try opening it via http://subdomain.yoursite.com/random.html. Then you can try some stuff like:
RewriteRule ^random.html - [F]
...and if that blocks access to file, try prepending
RewriteCond ${SERVER_NAME} ^subdomain\.yoursite\.com$ [nc]
to previous rule, to block access to that file, to make sure that rewrite engine is actually hitting your rules. That would target only desired subdomain (www.yoursite.com/random.html should work, but access via subdomain shouldn't).
Then if those rules work, it's just a matter of adding more stuff and see when it stops working.
RewriteRules are a bitch.
The following should work:
.htaccess:
RewriteCond ${SERVER_NAME} !^(www|ftp|mail)\.example\.com$
RewriteCond ${SERVER_NAME} !^([^.]+)\.example\.com$
RewriteRule .* redirect.php?to=%1
redirect.php
<?php
$desired_server_name = 'http://example.com';
$subdir = 's_' . $_GET['to'];
$url = $desired_server_name . '/' . $to . $_SERVER['REQUEST_URI'];
// Permanent redirects
header('HTTP/1.1 301 Moved Permanently');
// Or simple redirects:
header('HTTP/1.1 302 Found');
header('Location: '.$url);
?>
Works on my server (debian 4/apache 2).
Bonus: do not EVER use HTTP_HOST! See the following request:
HTTP/1.1 GET /foo/bar.php
Host: www.host.tld"><script>alert(/Hello/)</script
Connection: close
If you use $_SERVER['HTTP_HOST'] in your .php scripts to construct links or .htaccess rules for that matter and "www.host.tld" is the virtual-host or the only host configured for Apache, the XSS in the HTTP request header will be passed down unescaped.
We have a similar thing working on our Virtual Machines, where we redirect anything.usertld to a folder for that domain, that was in httpd.conf, tried in in the .htaccess and like yours it didn't work.
Tweaking it, this works for me (my VM occupies a tld called benb, but changing it to your domain should be fine):
RewriteCond %{HTTP_HOST} !^www\.benb
RewriteCond %{HTTP_HOST} ^(.*)\.benb
RewriteCond %{REQUEST_URI} !^/{0,1}s_
RewriteRule ^(.*)$ s_%1/$1 [L]
Also this captures all the text before the domain.. you should be able to change:
RewriteCond %{HTTP_HOST} ^(.*)\.benb
to
RewriteCond %{HTTP_HOST} ^([^.]+)\.benb
to handle just 1 level of subdomain. Also your other part about (www|ftp|mail) would work fine too.
