Add A 301 Redirect to Codeigniter .htaccess - .htaccess

I've been trying to set up a redirect for a page that recently moved. The page was originally at http://example.com/foo/, but has since moved to http://example.com/foo/bar/ .
I tried the following rule in my sites .htaccess file:
RedirectMatch 301 ^/foo/$ /foo/bar/
However going to the url http://example.com/foo/ resulted in a redirect to the url http://example.com/foo/bar/?/foo/. While the url works and the page I want to redirect to loads, I would quite like to get rid of the extra ?/foo/ at the end of the url.
Here is my full .htaccess:
RewriteEngine On
RewriteBase /
# add trailing slash
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} !(.*)/$
RewriteRule ^(.*)$ $1/ [R=301,L]
# allow access to certain directories in webroot
RewriteCond $1 !^(index\.php|robots\.txt|css/|lib/|js/|images/|^(.*)/images)
# gets rid of index.php
RewriteRule ^(.*)$ index.php?/$1 [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# page redirects
RedirectMatch 301 ^/foo/$ /foo/bar/

Adding a RewriteRrule to the top of the .htaccess after the RewriteBase / file solved the problem.
RewriteRule ^foo/$ /foo/bar [R=301,L]

I found it easier to redirect from controller instead of .htaccess because .htaccess was adding a querystring at the end.
For example I've put this in my controller's action:
if ($this->uri->segment(2)==='old_url') {
redirect(base_url() . $this->lang->lang() .'/new-url', 'location', 301);
}

Implementing "friendly" URLs using .htaccess

I tried some of the other answers I could find in here, but it didn't work out. It's really simple though.
I want
/page?id=PAGENAME
to be accessible AND redirected to
/PAGENAME
Can you help me?
EDIT:
It feels like my already messed-up .htaccess file needs to be included in here. I already have basic rewriting enabled, but this feature is needed for two other "special pages". In the requested solution above, I would therefore just replace "page" with the two pagenames (it's danish names, so I thought it was easier this way).
Currently I have this. If you have any improvements to it, it's appreciated - but I just want this to work with the requested solution aswell.

Generally the URL in address bar should be like
www.siteurl.com/pagename/ for seo purpose and then read this url from .htaccess using rule which gives this query string parameter values in your php file.
.htaccess rule can be like
RewriteRule ^(.*)/$ /page?id=$1 [QSA,L]
It looks like you are wanting to implement "friendly" (or "pretty") URLs, making the URLs more friendly for you users (search engines don't really mind what your URLs look like).
The first step is to change all your on-page links to use the new "friendly" URL. So, you links should all be of the form /pagename (not /page?id=PAGENAME).
Then, in .htaccess, you need to internally rewrite this "friendly" URL into the real URL that your server understands. This can be done using mod_rewrite. In the .htaccess file in your document root:
# Enable the rewrite engine
Options +FollowSymLinks
RewriteEngine On
# Rewrite the "friendly" URL back to the real URL
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{QUERY_STRING} !^id=
RewriteRule ^([\w-]*) /page?id=$1 [L]
If the file does not exist (!-f) and does not contain the id URL param then internally rewrite the request from /<pagename> to /page?id=<pagename>. This assumes your <pagename> consists only of the characters a-z, A-Z, 0-9, _ and -.
If this is a new site and the old URLs are not already indexed or referenced by external sites then you can stop here.
However, if you are changing an existing URL structure then you also need to externally redirect the real (ugly) URL to the "friendly" URL before the above internal rewrite. (This is actually what you are asking in your question.) In order to prevent a rewrite loop we can check against %{THE_REQUEST} (which does not change when the URL is rewritten).
# Redirect real URLs to "friendly" URLs
RewriteCond %{THE_REQUEST} \?id=([\w-]*)
RewriteRule ^page$ /%1? [R=302,L]
Change the 302 (temporary) to 301 (permanent) when you are sure this is working OK. Permanent redirects are cached by the browser so can make testing a problem.
So, in summary, with the above two parts shown together:
# Enable the rewrite engine
Options +FollowSymLinks
RewriteEngine On
# Redirect real URLs to "friendly" URLs
RewriteCond %{THE_REQUEST} \?id=([\w-]*)
RewriteRule ^page$ /%1? [R=302,L]
# Rewrite the "friendly" URL back to the real URL
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{QUERY_STRING} !^id=
RewriteRule ([\w-]*) /page?id=$1 [L]
The order of directives is important. External redirects should nearly always come before internal rewrites.
UPDATE#1:
I want /concept?id=NAME to go to /NAME and /studio?id=NAME to go to /NAME - there's 5-10 different "pages" from both concept and studio. [Corrected according to later comment]
Since id=NAME maps to /NAME you can achieve all 10-20 redirects with just a single rule:
RewriteCond %{QUERY_STRING} ^id=(NAME|foo|bar|baz|abc|def|ghi)
RewriteRule ^(concept|studio)$ /%1? [R,L]
This will redirect a URL such as /studio?id=foo to /foo.
As with all external redirects this should be one of the first rules in your .htaccess file.
Change R to R=301 when you have tested that it is working OK.
To make this more "dynamic", ie. match any "NAME" then change the CondPattern, for example:
RewriteCond %{QUERY_STRING} ^id=([\w-]*)
UPDATE#2:
If the path part of the URL (ie. concept or studio) is required then you can modify the RewriteRule substitution like so:
RewriteCond %{QUERY_STRING} ^id=([\w-]*)
RewriteRule ^(concept|studio)$ /$1/%1? [R,L]
Which will redirect /concept?id=foo to /concept/foo.
Or, to be completely "dynamic" (bearing in mind this will now capture anything):
RewriteCond %{QUERY_STRING} ^id=([\w-]*)
RewriteRule ^([\w-]+)$ /$1/%1? [R,L]

URL rewrite to remove trailing folder name

We have a server, and have several folders under the /var/www/ folder.
We have pointed our domain name to the IP of the server, and by default we expect to load one folder as the website (since its not possible to point a folder with DNS).
I have written .htaccess in such a way that when you enter the IP or the domain name, the request redirects to the website folder.
However, whenever we enter the IP or the domain name, the name of the folder is getting added to the URL.
Here is the present .htaccess:
Options +FollowSymlinks -Multiviews
#DirectoryIndex folder/
RewriteEngine on
ReWriteBase /
RewriteRule ^$ /folder [L]
RewriteRule ^$ folder/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s/+folder/([^\s]+) [NC]
RewriteRule ^ %1 [R=301,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule (?!^folder/)^(.*)$ /folder/$1 [L,NC]
where the folder is the folder's website
so,
www.domain.com
becomes
www.domain.com/folder/
Is there a way to rewrite the URL to remove the folder name?
Thanks in advance :)
EDIT : Added .htaccess code
Have your rule like this in DocumentRoot/.htacess:
DirectorySlash On
Options +FollowSymlinks -MultiViews
RewriteEngine on
ReWriteBase /
# redirect /folder/abc123 to /abc123
RewriteCond %{THE_REQUEST} \s/+folder/(\S*) [NC]
RewriteRule ^ /%1 [R=301,L,NE]
# skip rewrites for real files/directories
RewriteCond %{REQUEST_FILENAME} -d [OR]
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule !^(index\.)?$ - [L]
# route everything internally to /folder
RewriteRule ^((?!folder/).*)$ folder/$1 [L,NC]
It sounds like you made an external redirect instead of an internal rewrite. An external redirect is denoted by the [R] flag (with optional parameter) and causes Apache to send a 301 or 302 header back to the client with a different url that client should request. This causes the client to show the new url in the address bar.
What you want is an internal rewrite. When you request the url, the url is internally rewritten to the place where the resource is actually located. You do this by omitting the [R] flag, and not using a domain name in the rewritten part. It typically looks something like this:
RewriteCond %{REQUEST_URI} !^/folder
RewriteRule ^(.*)$ /folder/$1 [L]

Why isn't my .htaccess 301 redirect rule working?

I use URL rewriting on my redesigned website to give my pages tidier URLs.
RewriteEngine On
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteRule ^$ index.php [L]
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteRule ^.+/$ %{REQUEST_URI}index.php [L]
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteRule ^(.+\.php|(.+/)?index)$ - [R=404,L]
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteCond %{SCRIPT_FILENAME}.php -f
RewriteRule ^(.+)$ $1.php [L]
This .htaccess file allows /filename to actually point to /filename.php. It all works fine.
However, I have now realised that I should set up 301 permanent redirects, so that the pages of the old website (before the redesign) can redirect to pages on the new site (for SEO and linking reasons). The pages have been reorganised, so multiple old pages will redirect to new pages, for example.
The old website did not use URL rewriting. Therefore, I want to create permanent redirects such as /about-page.php to /about, doing them manually with one rule per old page.
I have tried several things, such as...
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteRule ^about-page.php$ about [R=301,L]
...or...
Redirect 301 /about-page.php /about
...but it always ends up either not working at all (giving me a 404 error when I attempt to access /old-filename.php, or breaks everything with internal server errors. It seems to work fine if I use Redirect 301 /about-page.html /about instead, but unfortunately the old URLs used .php extensions, not .html extensions.
I believe the problem is related to one of the other rules, which redirect requests for /xyz to /xyz.php, possibly creating some endless loop. But I can't figure out how to fix it.
Any advice? Thank you very much.
Edit: Final, working .htaccess file:
DirectoryIndex index.php #
RewriteEngine On
# -- Use a permanent redirect to point the old page to the new page.
# -- The RewriteCond is needed, or a redirect loop happens in certain cases.
# -- The full URL seems to be needed, or it redirects incorrectly.
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteRule ^about-page.php$ http://www.mywebsite.com/about [R=301,L]
# -- Redirect most other .php files to a 404 error, to avoid duplicate content.
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteRule ^(.+\.php|(.+/)?index)$ - [R=404,L]
# -- Redirect requests without an extension, but for a valid file, to that file.
# -- I'm not sure what the RewriteCond lines are for, but they both seem necessary.
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteCond %{SCRIPT_FILENAME}.php -f
RewriteRule ^(.+)$ $1.php [L]
DirectoryIndex index.php # -- this sets index.php to be default file for a folder
RewriteEngine On
# -- RewriteRule ^(.+\.php|(.+/)?index)$ - [R=404,L]
# -- dude this above line redirects all php files to 404 error
# -- so delete this, its a problem not solution
RewriteCond %{SCRIPT_FILENAME}.php -f
RewriteRule ^(.+)$ $1.php [L]
RewriteRule ^about-page.php$ /about [R=301,L]
This should work, comment if problem occurs

301 redirect from query string to simple URL

I've had a good look through the first ten pages of search results for "301 redirects" and can't find the answer so here goes...
I've moved from a crappy old CMS that didn't give my pages nice URLs to one that does and I want to set up a 301 redirect for my key pages.
Current URL: http://www.domain.com/?pid=22
New URL: http://www.domain.com/contact/
I'm using Wordpress and my current htaccess file looks like this:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
Any help would be awesome!
Give this a try. All you need to do is check to see if you are on page X and then redirect to page Y. Consider RewriteCond statements to be 'if' statements. If you need more redirects just duplicate the last two lines and edit the paths.
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} !^www\.domain\.com\/?pid=22$ [NC]
RewriteRule ^(.*)$ http://www.domain.com/contact [L,R=301]
You have to check the query string for the value in the "pid" variable and then redirect if the value in that variable matches a page you want to redirect. You can do this with the "RewriteCond" and "RewriteRule" directives like this:
RewriteEngine On
RewriteBase /
# Redirect pid=22 to http://www.domain.com/contact
RewriteCond %{QUERY_STRING} ^pid=22$
RewriteRule ^(.*)$ http://www.domain.com/contact [R=301,L]
You can repeat the "RewriteCond" and "RewriteRule" directives to create additional redirects.

301 All aspx files to a Subdomain

We just redesigned a site for a client in EE, located at example.com (with and without www.). Their original site is ASPX. They've still got a number of ASPX pages that they want to keep, so their IT people created a subdomain, www2, which is basically a clone of their old site.
I need an htaccess rule that will check if the requested page ends in .aspx, then redirects to the www2 subdomain. It should also make sure that the requested page doesn't exist
I tried using the following rule, but it doesn't work.
RewriteRule ^http://[www\.?]example.com/(.*)\.aspx$ http://www2.example.com/$1 [R=301,L]
My htaccess file (including the above rule) looks like this:
RewriteEngine On
# redirect all .aspx pages to www2
RewriteRule ^http://[www\.?]example.com/(.*)\.aspx$ http://www2.example.com/$1 [R=301,L]
# strip index.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php/$1 [L]
Does anyone have a solution for this?
The RewriteRule directive does only test the URL path. If you want to test any other part of the requested URL, you need to use the RewriteCond directive:
RewriteCond %{HTTPS} !=on
RewriteCond %{HTTP_HOST} ^(www\.)?example\.com$
RewriteRule ^(.*)\.aspx$ http://www2.example.com/$1 [R=301,L]
