Trouble redirecting subdomains to a folder - mod-rewrite

I have got this working:
RewriteEngine on
RewriteCond %{HTTP_HOST} ^([^\.]+)\.domain\.co\.uk
RewriteRule ^(.*) http://domain.co.uk/%1 [L]
So it will redirect test.domain.co.uk to test.domain.co.uk/test
However, I would like it so that it changes the document root rather than the user seeing the redirect. I have read a few articles on here and tried a few things. But I am not sure how to debug any errors, it just doesn't work. The one other that I have tried:
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_URI} !^/-
RewriteCond %{HTTP_HOST} ^([^\./]+)
RewriteCond %{DOCUMENT_ROOT}/-%1 -d
RewriteRule ^(.*)$ -%1/$1 [L]
But this doesn't seem to work at all.
Any help would be appreciated.

Try something like this in your document root:
RewriteEngine On
# check if subdomain folder has the existing file, if so, serve it
RewriteCond %{HTTP_HOST} ^([^\.]+)\.domain\.co\.uk
RewriteCond %{DOCUMENT_ROOT}/%1%{REQUEST_URI} -f
RewriteRule ^(.*)$ /%1/$1 [L]
# check if subdomain folder has the existing directory WITH A TRAILING SLASH, if so serve it
RewriteCond %{HTTP_HOST} ^([^\.]+)\.domain\.co\.uk
RewriteCond %{DOCUMENT_ROOT}/%1%{REQUEST_URI} -d
RewriteRule ^(.*?)/$ /%1/$1/ [L]
# check if subdomain filder has the existing directory but missing trailing slash, redirect with it
RewriteCond %{REQUEST_URI} !/$
RewriteCond %{HTTP_HOST} ^([^\.]+)\.domain\.co\.uk
RewriteCond %{DOCUMENT_ROOT}/%1%{REQUEST_URI} -d
RewriteRule ^(.*)$ /$1/ [R=301,L]
This method does 2 things for you, if it's a 404, it won't try to internally rewrite, so if you go to: http://sub.domain.co.uk/this/path/does/not/exist/blah, you won't get a 404 message saying: /sub/this/path/does/not/exist/blah doesn't exist, just /this/path/does/not/exist/blah because the URI wasn't rewritten, and thus not exposing your underlying directory structure.
The second thing is that you probably have DirectorySlash turned on. Which means if you access a directory like: http://sub.domain.co.uk/this/path, missing the trailing slash, mod_dir will want to redirect and add that slash, but it'll probably do it wrong because the URI has been rewritten and will redirect you to: http://sub.domain.co.uk/sub/this/path/. We you pre-emptively add the trailing slash with the correct URI hiding the sub.

Remove particular segment from url

I am using Codeigniter for one of my apps and have a following htaccess file
DirectoryIndex index.php
RewriteEngine on
RewriteCond $1 !^(index\.php|(.*)\.swf|forums|images|css|downloads|js|robots\.txt|favicon\.ico)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ ./index.php?$1 [L,QSA]
Now i have a url which is like mydomain.com/group/username
For SEO reasons i am suppose to convert this url into mydomian.com/group/username into mydomian.com/username using 301 redirect
Also urls like mydomain.com/group/username/page1 should redirect to mydomian.com/username/page
The closest i have tried after googling is by pasting this below line at the end of the file
RewriteRule ^(.*?)/?group(.*)$ /$1 [L]
But it isnt working.. any idea where i have gone wrong ?
The answers on other questions doesnt seem to be working for me/ Am pretty bad with .htaccess
P.S - i tried this
RewriteRule ^group/username(.*)$ username/$1 [QSA,R=301,L]
It works fine but it gives consecutive slashes like mydomain.com/username//pagename
I have figured it out
RewriteRule ^group/username(.*)$ username$1 [QSA,R=301,L]
This is will simply remove the 'group' from your URL and will do 301 redirect
If
RewriteRule ^group/username(.*)$ username/$1 [QSA,R=301,L]
gives two slashes, change it to:
RewriteRule ^group/username/(.*)$ username/$1 [QSA,R=301,L]
The (.*)$ matches anything after username (including the slash) until the end.

.htaccess syntax code needing revision

1) i am trying to 301 all non www's to www's (including files)
e.g. /subdirectory/ + /subdirectory/1.jpg (all possibilities with the www.)
2) i am trying to exclude ONLY but ALL .html and .php files from showing and would like only the non trailing version to be indexed, the rest to be 301's to my domain
e.g. /example.html or .php >> /example
e.g. /example.html or .php >> to not work + to not be indexed
e.g. /example to ONLY work and to ONLY be indexed (to avoid duplicate content)
3) i am trying to 301 all dead links and 404's to my domain
e.g. /deadlink or /deadlink.pdf >> 301'd to my domain, example.com
Here is the code i currently have, however i am not sure if it's 100% proper.
Can someone please reply with a validated syntax for these 3 tasks? Thanks.
Options +FollowSymLinks
RewriteEngine On
RewriteCond %{HTTP_HOST} ^example\.com$ [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [R=301,L]
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}\.php -f
RewriteRule ^(.*)$ $1.php
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}\.html -f
RewriteRule ^(.*)$ $1.html
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule . / [L,R=301]
OK, you've got three parts you're trying for here, and I'll address them all separately.
Before we begin, you only need to have one
RewriteEngine on
It only needs to be turned on once.
You should also set:
Options -MultiViews
as MultiViews can otherwise cause some weird issues here.
Redirect to WWW
Your current rules should work, but you can simplify them a little using the != prefix on RewriteCond:
RewriteCond %{HTTP_HOST} !=www.example.com
RewriteRule ^(.*)$ http://www.example.com/$1 [R=301,L]
Removing .php and .html suffixes
You need two separate sets of rules here: one to remove suffixes from URLs, and another to readd them internally.
Let's do the second half first, since that's easier:
RewriteCond %{SCRIPT_FILENAME}.html -f
RewriteRule ^(.*)$ $1.html [L]
RewriteCond %{SCRIPT_FILENAME}.php -f
RewriteRule ^(.*)$ $1.php [L]
With this in place, though, removing suffixes is a little tricky without conflicting with the rule that goes ahead and tries to put them back on. The best approach I was able to come up with was:
RewriteCond %{THE_REQUEST} \.(html|php)
RewriteRule ^(.*)\.(html|php)$ $1 [R=301,L,NC]
But I'm open to suggestions.
301ing all dead links
Don't do that. If a link doesn't exist, it should return a page with a 404 status. If you want to redirect visitors to your home page from dead links, put a link in your 404 page.

mod_rewrite forward shortend URL

I am looking for a way to create a short URL path for a longer URL on my page
the long url is: domain.com/tagcloud/user.html?t=1234ABCD
i would like to offer a short version of the URL to easy access it:
domain.com/t/1234ABCD
I tried a few examples but I just don't get it how I could forward these rules.
RewriteRule ^(.*)/t/$ /tagcloud/user.html?t=$1 [L]
I am also using MODX so they already use rules.
in addition my htaccess file
RewriteEngine On
RewriteBase /
# Always use www
RewriteCond %{HTTP_HOST} .
RewriteCond %{HTTP_HOST} !^www\.domain\.com [NC]
RewriteRule (.*) http://www.domain.com/$1 [R=301,L]
# The Friendly URLs part
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?q=$1 [L,QSA]
I must keep the code snippets above in my htaccess file. The first one simply forwards http://domain.com requests to www.domain.com
The friendly URLs part is needed to translate the internal IDs of my CMS with the alias of the URL. This feature must remain because the entire site cannot be influencted by the changes I try to make in htaccess...
I simply would like to add a listener that only if the URL matches www.domain.com/t/abcd1234
Therefore I need something that identifies the www.domain.com/t/ URL
your help is much appreciated
Try this:
RewriteCond %{REQUEST_URI} ^/t/.*
RewriteRule ^t/(.*)$ /tagcloud/user.html?t=$1 [R=301,L]

How to redirect an url with parameters?

I'm at a total loss trying to integrate a mod_rewrite in my existing page. Currently, I am building a new site from scratch, and there i have some nice clean url's such as:
http://www.example.nl/nl/example
The old site, running Cms made simple, has some not-rewritten url's that would need to be redirected to the new pages. Those url's look like this:
http://www.example.nl/index.php?page=cake-and-pie&hl=nl_NL
But shorter versions of that like:
http://www.example.nl/index.php?page=cake-and-pie
also work.
It took me a while to figure out that url's with parameters cannot simply be redirected with "Redirect 301", like i'd normaly do. So i tried some online mod_rewrite generators like this and this, but the rules outputted by those result only in 404 errors, (the redirect doesn't work at all).
My .htaccess file current looks like this:
RewriteEngine On
RewriteBase /
# remove .php;
RewriteCond %{THE_REQUEST} ^GET\ (.*)\.php\ HTTP
RewriteRule (.*)\.php$ $1 [R=301]
# remove index
RewriteRule (.*)/index$ $1/ [R=301]
# remove slash if not directory
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} /$
RewriteRule (.*)/ $1 [R=301]
# add .php to access file, but don't redirect
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteCond %{REQUEST_URI} !/$
RewriteRule (.*) $1\.php [L]
The old pages would seize to exist.
How do i redirect the old pages to the new ones?
Thanks.
EDIT
RewriteCond %{QUERY_STRING} =page=pie
RewriteRule ^index\.php$ /nl/? [L,R=301]
RewriteCond %{QUERY_STRING} =page=pie&hl=nl_NL
RewriteRule ^index\.php$ /nl/? [L,R=301]
Seems to do the trick. This is of course manual for every url, but i only have a few.
RewriteEngine On
RewriteBase /
RewriteRule ^(.+)/([^/]+)/?$ index.php?page=$1&hl=$2
RewriteRule ^([^/]+)/?$ index.php?page=$1 [QSA]

Why subdomain rewrite does not work?

I want my subdomain to point directly to a folder.
I have found the following mod_rewrite script to setup this behavior.
Unfortunately it does not work.
When I navigate to fish.example.com, the browser displays 404 error with the following message.
"The requested URL / was not found on this server."
Do you know why?
How can I make it work?
# Internally rewrite <subdomain>.example.com/<URLpath> to example.com/subs/<subdomain/<URLpath>
RewriteEngine on
RewriteCond $1 !^fish/
RewriteCond %{HTTP_HOST} !^www\.example\.com
RewriteCond %{HTTP_HOST} ^([^.]+)\.example\.com
RewriteRule (.*) /fish/%1/$1 [L]
UPDATE
I have changed the script to the following, but in this case the browser redirects to example.com instead of example.com/fish
Do you know why?
RewriteCond $1 !^fish/
RewriteCond %{HTTP_HOST} !^www\.example\.com
RewriteCond %{HTTP_HOST} ^([^.]+)\.example\.com
RewriteRule ^fish/(.*) /fish/%1/$1 [L]
Try this:
RewriteEngine On
Rewrite Base / # Make sure it starts from the domain
RewriteCond %{HTTP_HOST} ^fish.example.com [NC] # Catch your subdomain
RewriteRule (.*)$ fish/$1 [L] # Reroute to folder.
Update:
I see... try this:
RewriteCond $1 !^fish/
RewriteCond %{HTTP_HOST} !^www\.example\.com
RewriteCond %{HTTP_HOST} ^([^.]+)\.example\.com
RewriteRule (.*) http://example.com/%1/$1 [R=301,L]
Basically a 301 redirect... %1 matches the subdomain in the previous RewriteCond, and $1 matches the original url
