Rewrite part of url with .htaccess - apache

I need to rewrite URL and save top level domain and query.
I tried to use these rules
RewriteEngine On
RewriteBase /
RewriteRule ^domain(.*)$ http://newdomain$1 [R=302,NE,L]
Using this testing tool I found that it works if domain.com/query?param=value is used as a request URL. But if I try to use http://domain.com/query?param=value[ it doesn't work.
Basically I don't care what protocol is (http or https), I just need to replace first occurrence of domain string and rewrite it with newdomain saving all other parts of a request URL.

As it turned out in your comment to the first answer I gave you are actually trying to replace only part of the hostname of the incoming request but keep path and query string. That was not clear to me from your question, sorry.
You have to use an additional RewriteCond for this, since as said before you caanot access the hostname at all inside a RewriteRule. So I guess the following goes into the direction of what you are actually looking for:
RewriteEngine on
RewriteBase /
RewriteCond %{HTTP_HOST} ^[^\.]+\.(.+)$
RewriteCond %{HTTP_HOST} !^newdomain\.(.+)$
RewriteRule ^(.*)$ http://newdomain.%1/$1 [R=301,L,QSA]
You may want to try this modification to preserve the original request scheme too:
RewriteEngine on
RewriteBase /
RewriteCond %{HTTP_HOST} ^[^\.]+\.(.+)$
RewriteCond %{HTTP_HOST} !^newdomain\.(.+)$
RewriteRule ^(.*)$ %{REQUEST_SCHEME}://newdomain.%1/$1 [R=301,L,QSA]

.htaccess RewriteRule from long url to show short url

Im trying to rewrite url from long to short but cant wrap my head around this.
My survey rewrite works wonderfully but after completing my survet php redirects to www.example.com/survey_thank_you.php?survey_id=1
but I would like to show url like www.example.com/thank_you
Im not even sure if this is possible.
Im new with .htaccess and i have tried almost everthing
.htaccess
Options +FollowSymLinks
Options -MultiViews
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^survey_thank_you.php?survey_name=([0-9a-zA-Z]+)/?$ Thank_you [L,NC,QSA]
RewriteRule ^([0-9a-zA-Z]+)/?$ survey_form.php?survey_name=$1 [L,NC,QSA] #works like charm.
Any help or directions will be highly appreciated.
Solution:
Options +FollowSymLinks
Options -MultiViews
RewriteEngine on
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteCond %{QUERY_STRING} ^survey_id=([0-9a-zA-Z]+)/?$
RewriteRule ^survey_thank_you\.php$ /%1/thank_you [R,L,QSD]
RewriteRule ^([0-9a-zA-Z]+)/thank_you$ survey_thank_you.php?survey_id=$1 [L,NC,QSA]
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^([0-9a-zA-Z]+)/?$ survey_form.php?survey_name=$1 [L,NC,QSA]
but after completing my survet php redirects to www.example.com/survey_thank_you.php?survey_id=1
You need to "correct" the URL that PHP is redirecting you to after the survey. If the desired URL is /thank_you (or /Thank_you?) then PHP should be redirecting to that URL.
You then use mod_rewrite in .htaccess to internally rewrite /thank_you back into the URL that your application understands. ie. /survey_thank_you.php?survey_id=1. However, therein lies another problem, where does the 1 (survey_id) come from in the query string? Presumably you don't want to hardcode this? So this would need to passed in the requested URL. eg. /1/thank_you or perhaps /thank_you/1?
However, is this really necessary? The resulting "thank you" page is not a page that should be indexed or a page that is normally navigated to by the user, so implementing a user-friendly URL here doesn't seem to be a worthwhile exercise?
RewriteRule ^survey_thank_you.php?survey_name=([0-9a-zA-Z]+)/?$ Thank_you [L,NC,QSA]
RewriteRule ^([0-9a-zA-Z]+)/?$ survey_form.php?survey_name=$1 [L,NC,QSA] #works like charm.
You are using a survey_name URL parameter (referencing an alphanumeric value) in your directives, but a survey_id ("numeric"?) URL parameter in your earlier example? So, which is it? Or are these rules unrelated?
You state that the second rule "works like charm", but how? What URL are you requesting? That would seem to rewrite /Thank_you to survey_form.php?survey_name=Thank_you - but that does not look correct?
As mentioned in comments, the RewriteRule pattern matches against the URL-path only. To match against the query string you need an additional condition that matches against the QUERY_STRING server variable. This would also need to be an external 3xx redirect, not an internal rewrite (in order to change the URL that the user sees). Therein lies another problem... if you don't change the URL that your PHP script is redirecting to then users will experience two redirects after submitting the form.
You also need to be careful to avoid a redirect loop, since you are internally rewriting the request in the opposite direction. You need to prevent the redirect being triggered after the request is rewritten. ie. Only redirect direct requests from the user should be redirected.
So, to answer your specific question, it should be rewritten something like this instead:
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteCond %{QUERY_STRING} ^survey_name=[0-9a-zA-Z]+/?$
RewriteRule ^survey_thank_you\.php$ /Thank_you [QSD,R,L]
The check against the REDIRECT_STATUS environment variable ensures that only direct requests are processed, not internally rewritten requests by the later rewrite. REDIRECT_STATUS is empty on the initial request and set to the string 200 (as in 200 OK status) after the first successful rewrite.
The QSD flag (Apache 2.4) is necessary to discard the original query string from the redirect response.
So the above would redirect /survey_thank_you.php?survey_name=<something> to /Thank_you.
But this is losing the "survey_name" (or survey_id?), so should perhaps be more like the following, in order to preserve the "survey_name":
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteCond %{QUERY_STRING} ^survey_name=([0-9a-zA-Z]+)/?$
RewriteRule ^survey_thank_you\.php$ /%1/Thank_you [QSD,R,L]
Where %1 is a backreference to the value of the survey_name URL parameter captured in the preceding CondPattern.
However, you would then need to modify your rewrite that turns this back into an understandable URL.
(But you should probably not be doing this in the first place without first changing the actual URLs in the application.)

Redirect URL (including port) with params using .htaccess

I am trying to redirect from
http://www.example.com:81/my/api/search?query=test
to
http://www.example.com:81/my/php/api.php?query=test
using
RewriteCond %{QUERY_STRING} ^query=(.*)$
RewriteRule ^api/search(.*)$ /php/api.php?%1 [L]
However, it doesn't work for me. Additionaly for testing htaccess rules I use http://htaccess.madewithlove.be/.
Possibly even better would be to check if request starts from ^api and it's GET type (I guess using RewriteCond %{REQUEST_METHOD}) then redirect to /my/php/api.php?[query params here]
Anyone can point me into right direction?
If your .htaccess is located in /my/ directory then you can use:
RewriteEngine On
RewriteBase /my/
RewriteCond %{QUERY_STRING} ^query=.
RewriteRule ^api/search/?$ php/api.php [L]
QUERY_STRING will be automatically carried over to target URL.

How to use htaccess Rewrite rule for just part of a url

I am trying to create a rewrite rule in my httacess file for part of the url. I want to rewrite the url if the request contains a specific string. For example change the url only if contains /members/
So
mydomain.com/members/
mydomain.com/members/activity/ros1...
mydomain.com/members/ay/bd...
ALL above should change to another url because matches /members/ string in the url
RewriteEngine on
RewriteCond %{THE_REQUEST} ^GET /members/(.*)
RewriteRule ^(.*)$ - [F,L]
RewriteEngine on
RewriteCond %{REQUEST_URI} ^/members(.*)
RewriteRule ^(.*)$ - [F,L]
I have tried various combinations but does not seem to work. I'm sure I'm doing something really wrong as not on expert on this. Appreciate any pointers.
RewriteCond %{REQUEST_URI} ^/members
RewriteRule ^(.*)$ http://www.google.com/$1 [R, 301]
Would be something i would try to redirect a request for /members and send them to another domain. (with the same request uri). Further info on mod_rewrite can be found https://httpd.apache.org/docs/2.4/mod/mod_rewrite.html#rewriterule
You are using the F flag in your rewrites. The flag is to send the Forbidden status back to client. If you want to redirect the user to another URL, you'll need to pass that URL as the second parameter to RewriteRule directive with the R flag:
RewriteEngine On
RewriteRule ^members\b http://some-other-website.com [R]

Mod Rewrite, Unexpected Results

We are trying to redirect everything from one domain to another with the following
RewriteEngine on
RewriteCond %{HTTP_HOST} !^www\.example\.com$ [NC]
RewriteRule .? http://www.example2.com%{REQUEST_URI} [R=301,L]
When we visit http://www.example.com/v2sc
We are being redirected to http://www.example2.comv2sc
We would like to be redirected to http://www.example2.com/v2sc considering www.example2.comv2sc is not a valid hostname
Any ideas on how we can accomplish this?
Thank you!
It seems like you're using a .htaccess file for this. In that context the leading slash is not present in %{REQUEST_URI} so it's up to you to put it back in.
RewriteEngine On
RewriteCond %{HTTP_HOST} !=www.example.com
RewriteRule ^ http://www.example2.com/%{REQUEST_URI} [R=301]
Please also note that solutions like this should be used only if you cannot edit the main server configuration file. Doing so would allow you to use a cleaner combination of vhosts and Redirect directives that would run much more quickly.

htaccess redirect all requests from subfolder to subdomain

I have the following (WordPress) URL canonical structure:
http://mysite.com/2011/10/my-post-name/
I want to send all requests from http://mysite.com/2011/... down to the same location on a subdomain.
So specifically that should be:
http://mysite.com/2011/10/my-post-name/ ---> http://subdomain.mysite.com/2011/10/my-post-name/
I'm not sure what the correct syntax is for this, does anyone know?
RewriteEngine on
RewriteCond %{HTTP_HOST} ^mysite.com$
RewriteRule (.*) http://subdomain.mysite.com$1 [R=301]
If you also need to match the first part of the path, then use
RewriteEngine on
RewriteCond %{HTTP_HOST} ^mysite.com$
RewriteRule ^/2011/(.*) http://subdomain.mysite.com/2011/$1 [R=301]
You should read the mod_rewrite documentation. It's confusing the first time, but after the 25th time or so it will make pretty good sense and serve you well.
