Redirect to same domain with htaccess - apache

I want to redirect a user via htaccess when a specific HTTP_REFERRER is set. Here is my current htaccess
RewriteEngine On
RewriteCond %{HTTP_REFERER} ^(.*)\.example.org [NC]
RewriteRule ^(.*)$ https://example.com/blocked/$1 [L,R]
The problem I am facing now is that the HTTP_REFERRER still persists and I end within an endles redirection to /blocked/blocked/blocked
Is there any easy way to simple redirect/forward the user just ones to /blocked?


You need to exclude the /blocked URI in Rewrite to avoid the loop error
RewriteEngine On
RewriteCond %{HTTP_REFERER} ^(.*)\.example.org [NC]
RewriteCond %{REQUEST_URI} !/blocked
RewriteRule ^(.*)$ https://example.com/blocked/$1 [L,R]

.htaccess rewrite rule for subdomain

I would like to write a rule in my .htaccess to rewrite the url to enable my subdomain to show the content of a page from my site.
For example, I would like http://subdomain.example.org/page to show the content of the page http://example.org/subdomain/page.
I tried to write some rules as follow but it did not work
RewriteCond %{HTTP_HOST} ^subdomain.example.org$
RewriteCond %{REQUEST_URI} !^/subdomain/
RewriteRule ^(.*)$ /subdomain/$1 [L]
RewriteCond %{HTTP_HOST} ^subdomain.example.org$ [NC]
RewriteRule ^((?!subdomain).*)$ example.org/subdomain/$1 [NC,L]
Those rules end up raising an Internal Server Error
I also tried the last rule
RewriteCond %{HTTP_HOST} subdomain.example.org
RewriteRule ^(.*)$ http://example.org/subdomain$1 [L]
But this rule end up redirecting to http://example.org/subdomain and not just showing the content of the page while keeping the url.
What should be the right way to write the rule ?

Show contents of other folder based on subdomain htaccess

When i request:
subdomain1.domain.com
i want to show the contents of /httpdocs/subdomain1/
When i request
subdomain2.domain.com
i want to show the contents of /httpdocs/subdomain2/
I want to keep subdomain2.domain.com without redirect
i have a Wildcard on my Plesk, i just don´t know how to set up htaccess
i tried this so far, but is not working
RewriteCond %{HTTP_HOST} !^www\.
RewriteCond %{HTTP_HOST} ^([^\.]+)\.domain\.com$
RewriteRule ^ http://subdomain.domain.com/%1%{REQUEST_URI}

Don't use http:// in target otherwise it will do a full redirect not just silent rewrite as you want.
You can use:
RewriteEngine On
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteCond %{HTTP_HOST} ^(?!www\.)([^.]+)\.domain\.com$ [NC]
RewriteRule ^ %1%{REQUEST_URI} [L]
RewriteCond %{ENV:REDIRECT_STATUS} ^$ will ensure we rewrite only once.

Redirection is not working with mod_rewrite in htaccess

I need to redirect few URIs having query string like:
/pages/foo.bar?pageId=123456 to http://some.site/spam/egg/
/pages/foo.bar?pageId=45678 to http://another.site/spaming/egging/
I have this in my htaccess:
RewriteEngine On
RewriteCond %{REQUEST_URI} ^/pages/foo.bar$
RewriteCond %{QUERY_STRING} ^pageId=123456$
RewriteRule ^.*$ http://some.site/spam/egg/ [R=301,L]
RewriteCond %{REQUEST_URI} ^/pages/foo.bar$
RewriteCond %{QUERY_STRING} ^pageId=45678$
RewriteRule ^.*$ http://another.site/spaming/egging/ [R=301,L]
But its not working, showing 404. What am i doing wrong?

You need to move these 2 rules i.e. before all other rules just below RewriteEngine On line as other rules might be overriding this.
(Based on your comments) Your culprit rule is this rule:
RewriteRule . index.php [L]
Which is actually rewriting every request to index.php and changing value of REQUEST_URI variable to /index.php thus causing this condition to fail:
RewriteCond %{REQUEST_URI} ^/pages/foo.bar$

From your example, you get redirected to
http://some.site/spam/egg/?pageId=123456
http://another.site/spaming/egging/?pageId=45678
You can use your browser developer tools to see the redirection (in the Network tab).
Maybe the query strings in the redirected URL lead to a 404? You can add a ? at the end of your redirection to clear the query string:
RewriteCond %{REQUEST_URI} ^/pages/foo.bar$
RewriteCond %{QUERY_STRING} ^pageId=45678$
RewriteRule ^.*$ http://another.site/spaming/egging/? [R=301,L]

.htaccess rewrite rule causes endless loop

I want my .htaccess file to redirect to some page if any wildcard as a subdomain entry hit the browser. i.e. I want
sam.xyz.com
To redirect to
sam.xyz.com/view.php?id=sam
I am using following rewrite rules for redirect.
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www.xyz.com [NC]
RewriteCond %{HTTP_HOST} ^([^.]+).xyz.com
RewriteRule ^(.*)$ /view.php?id=%1 [L,R]
Problem i am facing is that it does not shift to new domain keeping query string instead it generates an endless loop
sam.xyz.com
redirects to
http://sam.xyz.com/view.php?id=sam
But doesnt move to url above without endless loop.
Kindly help me out.
Thanks in advance,

you should add a condition for redirect to prevent redirection loop:
RewriteCond %{REQUEST_URI} !^/view\.php
the whole code would be:
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www.xyz.com [NC]
RewriteCond %{HTTP_HOST} ^([^.]+).xyz.com
RewriteCond %{REQUEST_URI} !^/view\.php
RewriteRule ^(.*)$ /view.php?id=%1 [L,R]

You are redirecting to: prefix.domain.tld/view.php?id=prefix
Ensure that the url does not contain: id=prefix.
This solution prevents, that someone call's the url: aaa.example.com/view.php?id=bbb
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www.xyz.com [NC]
RewriteCond %{HTTP_HOST} ^([^.]+).xyz.com
RewriteCond %1::%{QUERY_STRING} !^([^:]+)::.*id=\1
RewriteRule ^ /view.php?id=%1 [L,R]
Note: (.*) in the rewrite rule is obsolete.
Leave the R away to do not redirect the visitor to the url (/view.php?id=%1)

.htaccess rewrite and subdomains

I have a subdomain setup as onlinedev.domain.com
I need to use htaccess to rewrite to domain.com/online_content, while still showing onlinedev.domain.com in the address bar (SSL is for onlinedev.domain.com).
this is what I currently have that is very close:
php_flag display_errors off
RewriteEngine On
RewriteCond %{HTTP_HOST} !^$
RewriteCond %{HTTP_HOST} onlinedev\.domain\.com$ [NC]
RewriteCond %{HTTP_HOST}<->%{REQUEST_URI} ^(www\.)?([^.]+).*<->/([^/]+) [NC]
RewriteCond %2<->%3 !^(.*)<->\1$ [NC]
RewriteRule ^(.+) /%2/$1 [L]
This correctly rewrites to domain.com/onlinedev, but if I try to change the RewriteRule to:
RewriteRule ^(.+) /online_content/$1 [L]
I get an error
I understand that there are typically better ways to do this subdomain work, but without getting into server config and DNS details, I need to do it with htaccess.
And yes, I do need to rewrite to a directory that has a different name than the subdomain.

Well, I figured it out.
The issue was that I was causing an infinite loop.
Once the rewrite had happened, it was still trying to rewrite to the directory.
Here is my new htaccess that took care of it:
RewriteEngine On
RewriteCond %{HTTP_HOST} !^$
RewriteCond %{HTTP_HOST} onlinedev\\.domain\\.com$ [NC]
RewriteCond %{REQUEST_URI} !^/online_content/
RewriteRule ^(.+) /online_content/$1 [L]
Notice that I added a check to make sure that the REQUEST_URI is not the name of the directory I am rewriting to.

Try this rule:
RewriteCond %{HTTP_HOST} =onlinedev.example.com [NC]
RewriteCond $0 !^online_content/
RewriteRule .+ /online_content/$0 [L]
