Remove trailing dot in URL domain - .htaccess

We have URLs of the form:
www.dev-studio.co.uk.
www.dev-studio.co.uk./a-sample-image
With the help of .htaccess rules, I am trying to remove the trailing dot (co.uk.) in the end of the domain name but I'm failing.
This is the rule I'm trying:
RewriteCond %{HTTP_HOST} ^([a-z0-9\.-]+)(\.co\.uk\.)(.*)$
RewriteRule ^ http://www.dev-studio.co.uk/%3 [L,R=302,NE]
But the %3 which should capture the 3rd group is returning empty.
The goal is to simple redirect www.dev-studio.co.uk./a-sample-image to www.dev-studio.co.uk/a-sample-image
I have tried all the other questions over here but the solutions are not working for me.
Any help would be appreciated.

RewriteCond %{HTTP_HOST} ^([a-z0-9\.-]+)(\.co\.uk\.)(.*)$
RewriteRule ^ http://www.example.co.uk/%3 [L,R=302,NE]
The HTTP_HOST server variable contains the hostname only (ie. the value of the Host HTTP request header), it does not contain the URL-path, so the %3 backreference is always empty.
You need to either capture the URL-path from the RewriteRule pattern. For example:
RewriteRule (.*) http://www.example.co.uk/$1 [R=302,L]
Or, use the REQUEST_URI server variable (which contains the full URL-path, including slash prefix) instead:
RewriteRule ^ http://www.example.co.uk%{REQUEST_URI} [R=302,L]
This should ultimately be a 301 (permanent) redirect, once you have confirmed it works OK.
Note that since you are redirecting to a specific domain, do you need a CondPattern that matches any .co.uk hostname? You could be specific:
RewriteCond %{HTTP_HOST} =www.example.co.uk.
RewriteRule ^ http://www.example.co.uk%{REQUEST_URI} [R=302,L]
The = prefix on the CondPattern changes it to a lexicographical string comparison (not a regex), so no need to escape the dots.
If you wanted an entirely generic solution to remove the trailing . (FQDN) from any requested host then you could do something like:
RewriteCond %{HTTP_HOST} (.+)\.$
RewriteRule ^ http://%1%{REQUEST_URI} [R=302,L]
Although you might want to combine this with your canonical redirects (eg. non-www to www / HTTP to HTTPS?) to avoid multiple redirects - although they are probably unlikely to occur all at once anyway, so probably not an issue.

htaccess redirect with query string not working

enter code hereI have a WordPress website.
I have URLs for affiliates that look like this:
https://example.com/folder/?ref=23432
https://example.com/folder/?ref=13442
etc.
I would like to redirect any URL that ends in ?ref= to another domain.
For example, https://example.com/folder/?ref= should redirect to https://example.org/product/
How can I do this? I appreciate your time.
I tried
Redirect 301 example.com/folder/?ref https://example.org/product/
Thank you #MrWhite. I tried the following with no success.
RewriteEngine On
RewriteCond %{QUERY_STRING} (^|&)ref=
RewriteRule ^example.com https://www.example.org/product/$0 [R=302,L]
RewriteRule ^example.com https://www.example.org/product/$0 [R=302,L]
The RewriteRule directive matches the URL-path only (less the slash prefix). So this should be matching against folder/ (as per your example), not the hostname.
And the $0 backreference in the substitution string is not required here. So this should simply be:
:
RewriteRule ^folder/$ https://www.example.org/product/ [R=302,L]
If you do need to check the requested hostname (ie. example.com) - if example.com and example.org point to the same server - then you need a separate condition (RewriteCond directive). For example, the complete rule would then become:
RewriteCond %{HTTP_HOST} ^(www\.)?example\.com [NC]
RewriteCond %{QUERY_STRING} (^|&)ref=
RewriteRule ^folder/$ https://www.example.org/product/ [R=302,L]
Note that the regex (^|&)ref= matches the ref= URL parameter anywhere in the query string, if there happened to be other URL parameters that preceded it.

.htaccess redirect question mark with no parameters

I have several URLs with question marks that need to be removed. For example, I need to redirect this URL:
http://example.net/?/services
To this URL:
http://example.net/services
I have many more like this, so I would like something that can catch everything with the question mark and properly redirect it. Many of the answers I found were trying to use QUERY_STRING as the condition for the rewrite, but without parameters this does not help. After some digging I found a RewiteCond that works, but the RewriteRule redirects to the homepage, rather than the URL without the question mark. What I have currently is this:
# Remove question mark from string
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /(index\.php)?\?([^&\ ]+)
RewriteRule ^ /%1? [L,R=301]
# Removes index.php from ExpressionEngine URLs
RewriteCond %{THE_REQUEST} ^GET.*index\.php [NC]
RewriteRule (.*?)index\.php/*(.*) /$1$2 [R=301,NE,L]
# Directs all EE web requests through the site index file
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php?/$1 [L]
The first block is the rewrite that I have so far, and the next two are for the CMS url routing. What seems to be happening is that my rewrite in the first block is not keeping the rest of the url. I have tried several combinations and can't seem to figure out how to keep the rest of the url intact.
Many of the answers I found were trying to use QUERY_STRING as the condition for the rewrite, but without parameters this does not help.
Yes, this is exactly what the first URL, with a question mark, contains. So, I'm not sure why "this does not help"? In the URL http://example.net/?/services, /services is the query string. Whether there are key/value pairs (ie. "parameters") is irrelevant.
To redirect URLs of the form http://example.net/?/services, that consist of no URL-path and only a query string, try something like:
# Remove question mark from string
RewriteCond %{QUERY_STRING} ^/(.+)
RewriteRule ^$ /%1? [R,L]
%1 is a backreference to the captured group in the last matched CondPattern (ie. (.+), which captures services). This assumes that the query string (after the ?) always starts with a slash, as in your example. (Incidentally, this is also what your front controller is doing, in reverse, so I assume it must be correct.)
The trailing ? on the substitution removes the original query string from the request.
Make sure you clear your browser cache, as any earlier/erroneous 301s will have been cached by the browser.
If this is intended to be a permanent (301) redirect then change R to R=301, but only when you are sure it's working OK.

friend url on wildcard subdomains htacces, not working

i have wildcard subdomains sets already and works fine, now i wish have friends url for the content in thats subdomains, the structure of my site is if the user type subdomain.maindomain.com and the .htaccess redirect to
blogs/index.php?user=subdomain
where blogs/index.php receive the param and show the correct content
now i try to make the url function like this
subdomain.maindoamin.com/24/title-of-content
and then .htaccess must result
blogs/index.php?id_content=24&title=title-of-content
i have the next .htaccess
Options +FollowSymLinks
#this force to server the content always without www.
RewriteEngine on
RewriteCond %{HTTP_HOST} ^www\.(.*)$
RewriteRule ^(.*)$ http://%1/$1 [R=301]
#this is to pass the subdomain like param and show the right content of the user
RewriteCond %{HTTP_HOST} !^www\.misite\.com [NC]
RewriteCond %{HTTP_HOST} ^([a-z0-9]+)\.misite\.com
RewriteRule ^(.*)$ blogs/index.php?url=%1 [QSA,L]
#the next line i can't make work to make nice url
RewriteRule ^/(.*)/(.*)$ blogs/index.php?idP=$1&name=$2 [L]
not working because when i make in index.php
echo $_SERVER['REQUEST_URI'];
don't show idP=24 show /24/title-of-content and i need $_GET(idP)
i really apreciate some light on this stuff i am not expert on htaccess, thanks in advance to everybody.
There are two problems:
The first argument of RewriteRule matches against everything after the slash of the directory .htaccess is in, and before the query string. If .htaccess is in your www-root, and you get the url http://www.example.com/shiny/unicorns.php?are=shiny, you match against shiny/unicorns.php. It will never start with a slash, so ^/ will never match.
Rules are executed in order. If you go to http://sub.example.com/10/unicorns, the second rule will match first and rewrite the request to /blogs/index.php?url=10/unicorns. If you removed the leading slash the third rule would match, but normally you wouldn't want that. You want to have the third rule only match
You want to move the third rule up so it is the second rule. You want to make it more specific to only match with subdomains. You also know the first part contains only numbers, so use that knowledge to prevent blogs/index.php from matching your now second rule. You also need to prevent blogs/index.php from matching the now third rule to prevent it from matching itself. Last but not least I removed [L] from the now second rule, since the third rule will match anyway.
#the next line i can't make work to make nice url
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^([0-9]+)/([^/]+)$ blogs/index.php?idP=$1&name=$2
#this is to pass the subdomain like param and show the right content of the user
RewriteCond %{HTTP_HOST} !^www\.misite\.com [NC]
RewriteCond %{HTTP_HOST} ^([a-z0-9]+)\.misite\.com
RewriteCond %{REQUEST_URI} !/blogs/index\.php
RewriteRule ^ blogs/index.php?url=%1 [QSA,L]

Stop hotlinking using htaccess and non-specific domain code

I need to write an anti-hotlink command for my .htaccess file but it can not be specific to any domain name in particular. Here's what I found on another sites so far but I'm not sure exactly why it doesn't work, can anyone spot the problem?
# Stop hotlinking.
#------------------------------
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} ^https?://([^/]+)/ [NC]
# Note the # is just used as a boundary. It could be any character that isn't used in domain-names.
RewriteCond %1#%{HTTP_HOST} !^(.+)#\1$
RewriteRule \.(bmp|gif|jpe?g|png|swf)$ - [F,L,NC]
Try this.
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} ^https?://(www\.)?([^/]+)/.*$ [NC]
RewriteCond %2#%{HTTP_HOST} !^(.+)#(www\.)?\1$ [NC]
RewriteRule \.(bmp|gif|jpe?g|png|swf)$ - [F,L,NC]
Would even work when only one of the referrer or target url has a leading www.
EDIT : (how does this % thing work?)
%n references the n(th) bracket's matched content from the last matched rewrite condition.
So, in this case
%1 = either www. OR "" blank (because it's optional; used ()? to do that)
%2 = yourdomain.com (without www always)
So, now the rewrite condition actually tries to match
yourdomain.com#stealer.com OR yourdomain.com#www.stealer.com
with ^(.+)#(www\.)?\1$ which means (.+)# anything and everything before # followed by www. (but again optional); followed by \1 the first bracket's matched content (within this regex; not the rewrite condition) i.e. the exact same thing before #.
So, stealer.com would fail the regex while yourdomain.com would pass. But, since we've negated the rule with a !; stealer.com passes the condition and hence the hot-link stopper rule is applied.

how to remove parts of a url with htaccess

My url contains a broken link due to the http:// prefix not being added in places. How would I replace this using mod_rewrite:
http://website.com/www.websitelink.com
should go here:
http://www.websitelink.com
RewriteRule ^www\.websitelink\.com$ http://www.websitelink.com/ [R=301,NC,L]
In other words, if your path is /www.websitelink.com (^ is start of string,$ is end of string; in regular expressions, dots are one-character wildcards and have to be escaped)
(and [NC] matching is not case sensitive - /WwW.webSiteLink.COM would match, too),
[R=301] redirect with status "301 (Moved Permanently)"
to http://www.websitelink.com/
and [L] leave processing (no more rewrite rules are processed).
Note that this will work regardless of the site's domain (would work e.g. for http://website.com/www.websitelink.com and http://www.website.com/www.websitelink.com )
If you want to match all the paths that end with your domain, drop the starting ^:
RewriteRule www\.websitelink\.com$ http://www.websitelink.com/ [R=301,NC,L]
and if you want to match even paths without www., make it optional:
RewriteRule (www\.)?websitelink\.com$ http://www.websitelink.com/ [R=301,NC,L]
As #Litso noted, this won't match the path after the "domain-in-path"; this should match the trailing path:
RewriteRule (www\.)?websitelink\.com/(.*)$ http://www.websitelink.com/$1 [R=301,NC,L]
To match any subdomain:
RewriteRule ([a-z0-9.-]+\.)?websitelink\.com/(.*)$ http://www.websitelink.com/$1 [R=301,NC,L]
And to match any domain:
RewriteRule ([a-z0-9.-]+\.)?([a-z0-9.-]+)\.com/(.*)$ http://www.$1.com/$2 [R=301,NC,L]
