I have an Apache server, which main rootwebdir is '/usr/www/users/foo/' and 'foo.com' points there. However, I have some subdomains pointing within their directories:
subdomain1.foo.com ---> /usr/www/users/foo/subdomain1
subdomain2.foo.com ---> /usr/www/users/foo/subdomain2
This causes me a problem: if anyone types 'www.foo.com/subdomain1/aboutme.html', they find 'subdomain1.foo.com/aboutme.html' with another URL, and I'd like to avoid it.
I wondered if there was any way to avoid this (e.g., showing a 404 page), by using a directive within the '.htaccess' file of '/usr/www/users/foo/subdomain1'.
Any other solution is welcome. Thank you very much.
You can rewrite requests to the combination of a specific subdomain and a specific path to a custom error document. That should the easiest:
RewriteEngine on
RewriteCond %{HTTP_HOST} !^subdomain1\.foo\.com$ [NC]
RewriteRule ^subdomain1 http://foo.com/not-found.html [L]
This can be done in a .htaccess style file or in the real http servers host configuration. The second option should be preferred whenever possible. .htaccess style files are notoriously error prone, hard to debug and the really slow down the server, often for nothing. They are only provided for situations where one does not have access to the real configuration (read: "cheap hosting providers") or where an application requires to write those files itself (which certainly is a security nightmare...).
The version for the http servers host configuration would be slightly shorter and more elegant, since the host is set implicitly:
RewriteEngine on
RewriteRule ^/subdomain1 http://foo.com/not-found.html [L]
You can use this rule in any subdomain directory's i.e subdomain1/.htaccess to block access using main domain foo.com:
RewriteEngine on
RewriteCond %{HTTP_HOST} ^(www\.)?foo\.com$ [NC]
RewriteRule ^ - [F]

Ok, so I know this is a question that has been asked many times, however, I have not been able to find an answer to my particular case, so please do not shoot me down.
I have a website: http://gmcomputers.co.za.
I am redirecting this URL, using .htaccess file, to a subfolder to load the content:
RewriteEngine on
RewriteCond %{REQUEST_URI} ^/$
RewriteRule (.*) /gmcomputers/ [L,DPI,R=301]
Which works perefectly, except when I go to http://gmcomputers.co.za I get http://gmcomputers.co.za/gmcomputers/.
So my question is, how do I modify the above code to remove the /gmcomputers/ from being appended?
Please note I copied the code above from a website as I am not at all experienced in redirect, etc and am still learning. Also, the reason I am using .htaccess to redirect is due to there being other websites in the root directory and I therefore cannot edit any config files for Apache.
Thanking you.
You contradict yourself in your question. On the one hand you write that you want to redirect and that this "works perfectly", but then you write that you do not want that result.
My guess is that you actually do not want to redirect at all, but that instead you want to internally rewrite your requests to point to that server side folder. While the URL visible in the browser's URL bar does not show that folder. Is that what you are trying to ask?
If so take a look at this example:
RewriteEngine on
RewriteCond %{REQUEST_URI} !^/gmcomputers
RewriteRule ^ /gmcomputers%{REQUEST_URI} [END]
You might want to add an actual redirection to direct clients actually using the folder name in their requests:
RewriteEngine on
RewriteRule ^/?gmcomputers/(.*)$ /$1 [R=301,END]
RewriteCond %{REQUEST_URI} !^/gmcomputers
RewriteRule ^ /gmcomputers%{REQUEST_URI} [END]
Best is to implement such rules in the central http server's host configuration. If you do not have access to that you can instead use a distributed configuration file (typically called ".htaccess") located in the DOCUMENT_ROOT folder configured for the http host, if you enabled the consideration of such files in your host configuration . Though that comes with a number of disadvantages. Above implementation works likewise for both approaches.
How can i direct the search engines from one domain to other domain for better SEO optimization. I want to make 301 redirect from domain.uk to language directory of another domain domain.com/gr
How can to change last line code? Thanks!
RewriteEngine on
RewriteCond %{HTTP_HOST} ^example-old\.uk$ [NC]
RewriteRule ^(.*)$ http://example-new.com/gr [R=301,L]
RewriteCond %{HTTP_HOST} ^example-old\.uk$ [NC]
RewriteRule ^(.*)$ http://example-new.com/gr [R=301,L]
You've not actually stated the problem you are having. However, if you want to redirect to the same URL-path, but with a /gr/ path segment prefix (language code) then you are missing a backreference to the captured URL path (otherwise there's no reason to have the capturing group in the RewriteRule pattern to begin with).
For example:
RewriteRule (.*) http://example-new.com/gr/$1 [R=301,L]
The $1 backreference contains the value captured by the preceding (.*) pattern.
I assume that is what you are looking for:
RewriteEngine on
RewriteCond %{HTTP_HOST} ^example-old\.uk$ [NC]
RewriteRule ^ http://example-new.com/gr%{REQUEST_URI} [R=301,END]
It is a good idea to start out with a 302 temporary redirection and only change that to a 301 permanent redirection later, once you are certain everything is correctly set up. That prevents caching issues while trying things out...
In case you receive an internal server error (http status 500) using the rule above then chances are that you operate a very old version of the apache http server. You will see a definite hint to an unsupported [END] flag in your http servers error log file in that case. You can either try to upgrade or use the older [L] flag, it probably will work the same in this situation, though that depends a bit on your setup.
This implementation will work likewise in the http servers host configuration or inside a distributed configuration file (".htaccess" file). Obviously the rewriting module needs to be loaded inside the http server and enabled in the http host. In case you use a distributed configuration file you need to take care that it's interpretation is enabled at all in the host configuration and that it is located in the host's DOCUMENT_ROOT folder.
And a general remark: you should always prefer to place such rules in the http servers host configuration instead of using distributed configuration files (".htaccess"). Those distributed configuration files add complexity, are often a cause of unexpected behavior, hard to debug and they really slow down the http server. They are only provided as a last option for situations where you do not have access to the real http servers host configuration (read: really cheap service providers) or for applications insisting on writing their own rules (which is an obvious security nightmare).
I'm new to htaccess and I need some help
how do I change the url automatically from from .htaccses
if I write url like:
url/index.php/pages
url will change automatic to:
url/pages
Thanks in advance.
This appears to be pretty straight forward, you would have found hundreds of existing answers and examples alone here on StackOberflow...
RewriteEngine on
RewriteRule ^/?index\.php/pages/?$ /pages [R=301]
This assumes that in your question, in the given path url/index.php/pages the "url" refers to a prefix of protocol scheme and host name, so would usually be written as https://example.com/index.php/pages...
It is a good idea to start out with a 302 temporary redirection and only change that to a 301 permanent redirection later, once you are certain everything is correctly set up. That prevents caching issues while trying things out...
I dare say however that you also need the corresponding internal rewrite to again be able to process such redirected requests. Adding that the example looks like this:
RewriteEngine on
RewriteRule ^/?index\.php/pages/?$ /pages [R=301]
RewriteRule ^/?pages/?$ /index.php/pages [END]
In case you receive an internal server error (http status 500) using the rule above then chances are that you operate a very old version of the apache http server. You will see a definite hint to an unsupported [END] flag in your http servers error log file in that case. You can either try to upgrade or use the older [L] flag, it probably will work the same in this situation, though that depends a bit on your setup.
This get more complex if your question does not only target the single, specific path /index.php/pages but actually any "pages" to follow in the path after the leading /index.php/. For that you'd need something a bit more complex:
RewriteEngine on
RewriteRule ^/?index\.php/(.*)$ /$1 [R=301]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !^/index\.php/
RewriteRule ^/?(.*)$ /index.php/$1 [END]
This implementation will work likewise in the http servers host configuration or inside a dynamic configuration file (".htaccess" file). Obviously the rewriting module needs to be loaded inside the http server and enabled in the http host. In case you use a dynamic configuration file you need to take care that it's interpretation is enabled at all in the host configuration and that it is located in the host's DOCUMENT_ROOT folder.
And a general remark: you should always prefer to place such rules in the http servers host configuration instead of using dynamic configuration files (".htaccess").

Basically I need to let through requests to a specific path:
https://domainfoo.com/my-app?param1=ABC¶mY=123
Anything else, let's say,
https://domainfoo.com/aboutus
I need it redirected to
https://moodomain.io/aboutus
I need this last part to be generic.
So Far I have this two rules:
To address the first requirement:
RewriteCond %{HTTP_HOST} ^domainfoo.com$
RewriteCond %{REQUEST_URI} ^/my\-app
RewriteRule ^(my\-app)$ https://domainfoo.com/$1 [L,R=301]
Then as a second rule (if first rule is matched (the L) should redirect and stop right? The thing is apparently it doesn't and then goes into the second rule:
RewriteCond %{HTTP_HOST} ^domainfoo.com$ [OR]
RewriteCond %{HTTP_HOST} ^www.domainfoo.com$
RewriteCond %{REQUEST_URI} !^/my\-app$
RewriteRule (.*)$ https://moodomain.io/$1 [R=301,L]
But I have been dealing for hours with a looped redirect.
Ideas?
You first rule codes the rewriting loop, since you implemented an external redirection where none is required at all. Here is a simplified version:
RewriteEngine on
RewriteCond %{HTTP_HOST} ^domainfoo\.com$
RewriteRule ^/?my-app$ - [END]
RewriteCond %{HTTP_HOST} ^domainfoo\.com$
RewriteRule ^/?(.*)$ https://moodomain.io/$1 [R=301]
It is a good idea to start out with a 302 temporary redirection and only change that to a 301 permanent redirection later, once you are certain everything is correctly set up. That prevents caching issues while trying things out...

And if you need to redirect clients "back" to the first domain, as you later stated in the comments to the question, then add an explicit redirection for that:
RewriteCond %{HTTP_HOST} !^domainfoo\.com$
RewriteRule ^/?my-app$ https://domainfoo.com/my-app [R=301]
I would like to htaccess-redirect all visitors from a subfolder of a domain to the same subfolder in another domain. That should apply to all subfolders and files - but only for the folder "folder"
For example:
foo.com/folder -> bar.com/folder
and with sub-structure
foo.com/folder/subfolder/file.php -> bar.com/folder/subfolder/file.php
All the posts I found were only concerning (sub)folders and not the domains.
Thanks!
Update: Thanks to the contributers - of course I tried to search, but Drupal blocked the redirects, so I didn't think the answers I found worked. Thanks anyways for the correct answer!
This should roughly be what you are looking for:
RewriteEngine on
RewriteRule ^/?(.*)$ https://example.com/$1 [END,QSA]
That rule will work likewise in the http servers host configuration and in dynamic configuration files (".htaccess").
In case you receive an "internal server error (http status 500)" with this chances are that you operate a very old version of the apache http server. In that case will find a hint on this in the http servers error log files. You need to replace the [END] flag with the [L] flag in that case.
In case you operate both domains as virtual hosts on a single http server you need to take care not to create an endless rewriting loop. In that case add a condition to prevent such loop:
RewriteEngine on
RewriteCond %{HTTP_HOST} !^example\.com$
RewriteRule ^/?(.*)$ https://example.com/$1 [END,QSA]
A general hint: you should always prefer to place such rules inside the http servers (virtual) host configuration instead of using dynamic configuration files (.htaccess style files). Those files are notoriously error prone, hard to debug and they really slow down the server. They are only provided as a last option for situations where you do not have control over the host configuration (read: really cheap hosting service providers) or if you have an application that relies on writing its own rewrite rules (which is an obvious security nightmare).
UPDATE:
In a comment below you mention that you want to apply such redirection only to a specific subfolder in the request path. To do that you just have to modify the matching pattern:
RewriteEngine on
RewriteCond %{HTTP_HOST} !^example\.com$
RewriteRule ^/?folder/(.*)$ https://example.com/folder/$1 [END,QSA]
An alternative would be that:
RewriteEngine on
RewriteCond %{HTTP_HOST} !^example\.com$
RewriteRule ^/?(folder/.*)$ https://example.com/$1 [END,QSA]
