Pass subdomain as parameter - regex

I'm new to ISAPI_Rewrite & I'm terrible with regular expressions. I'm in need of a rewrite rule for ISAPI_Rewrite that will remove the subdomain and pass it as a parameter. For example:
mysubdomain.mydomain.com
should become
mydomain.com/Landing.aspx?ID=mysubdomain
I've found a regex that seems to match all subdomains except www, but I'm not sure how to then pass the subdomain as a parameter as the example above shows.
^((?:(?!www).)*)
Any help would be appreciated.
Note: I'm using the full version of ISAPI_Rewrite so this rule will be at the site-level.
Global rule:
# Helicon ISAPI_Rewrite configuration file
# Version 3.1.0.89
#Disable extentionless processing for ASP.Net v 4.0
RewriteRule (.*)eurl.axd/.* $1
# Don't rewrite urls that are inside the assets folder or have the following extentions
RewriteRule ((^/Assets/.*)|(.*\.axd.*)|(.*\.asmx.*)|(.*\.png.*)) $1 [NC,L]
#Rewrite URL, pass last portion of URL to Landing.aspx + purl
RewriteRule (.*) $2/landing.aspx\?id=$1 [NC]

Something like this may work for you:
# Turn mod_rewrite on
RewriteEngine On
RewriteBase /
RewriteCond %{QUERY_STRING} ^$
RewriteCond %{HTTP_HOST} ([^.]+)(?<!^www)(\.|$) [NC]
RewriteRule ^ Landing.aspx?ID=%1 [L,QSA]
PS: Looks like your global rule is in conflict with above rule of mine. I would therefore suggest you to have your global rule like this to avoid conflict:
RewriteCond %{QUERY_STRING} ^$
RewriteCond %{HTTP_HOST} !mydomain\.com$ [NC]
RewriteRule ^(.*)$ landing.aspx?id=$1 [L]

Try using the following:
RewriteEngine on
RewriteBase /
RewriteCond %{HTTP:Host} !^www\.mydomain\.com$
RewriteCond %{HTTP:Host} ^([^.]+)\.mydomain\.com$
RewriteRule ^$ /Landing.aspx?ID=%1 [NC,L]
You did not specify if you want a 301-redirect or a rewrite,so in case you want it to be redirect, use [NC,R=301,L] instead of [NC,L].

Handle one query parameter specifically

I need to handle one query parameter specifically.
The url can look like the following:
https://example.com/?app=egov&map=1337
https://example.com/?app=egov&map=1337&showoptions=true
https://example.com/?app=egov&map=1337&showoptions=true&anotherparam=helloWorld
The redirect should point to
https://example.com/contextName/resources/apps/egov/index.html?map=1337
https://example.com/contextName/resources/apps/egov/index.html?map=1337&showoptions=true
https://example.com/contextName/resources/apps/egov/index.html?map=1337&anotherparam=helloWorld
As you can see, the app-Parameter needs to be used as an URL-part; the others need to be used like traditional query-params.
I've figured out, how to implement the first part, where https://example.com/?app=egov points to https://example.com/contextName/resources/apps/egov/index.html using the following
RewriteCond %{REQUEST_URI} ^/$
RewriteCond %{QUERY_STRING} ^app\=(.+)
RewriteRule ^/$ "/contextName/resources/apps/%1/index.html" [R,L,QSA]
but I'm struggeling how to realize the correct handling of the other params.
All these combination of query string can be handled by a single rule loke this:
RewriteEngine On
RewriteCond %{QUERY_STRING} ^app=([\w-]+)(?:&(.*))?$ [NC]
RewriteRule ^$ contextName/resources/apps/%1/index.html?%2 [L]
RewriteCond matches app query parameter and captures it in %1 while rest of the query string after & is captured in %2.
With your shown samples, please try following htaccess Rules file. Please make sure to clear your browser cache before testing your URLs.
RewriteEngine ON
####Apache documentation link https://httpd.apache.org/docs/trunk/rewrite/remapping.html for more info.
##Internal rewrite rule for URL https://example.com/?app=egov&map=1337

##Internal rewrite rule for URL https://example.com/?app=egov&map=1337&showoptions=true
RewriteCond %{QUERY_STRING} ^app=([^&]*)&map=(\d+)&showoptions=(.*)$ [NC]
RewriteRule ^/?$ contextName/resources/apps/%1/index.html?map=%2&showoptions=%3 [L]

RewriteRule ^/?$ contextName/resources/apps/%1/index.html?map=%2&anotherparam=%4 [L]
All of your URLs uri part is NULL, so rules are written based on that.

How to create .htaccess for multiple parameters in URL?

I need using this .htaccess file. It only changes the URL from www.mydomain.com/users/user?usernam=myname123&profile=myprofile123&data=mydata123 to www.example.com/users/myname123/myprofile123/mydata123 .
i use
RewriteEngine On
RewriteRule ^user\.php$ - [L]
RewriteRule ^([0-9a-zA-Z\-_.]*)/?$ /users/user.php?username=$1&profile=$2&data=$3[L,QSA]
htaccess in users folder
not work
With your shown samples, could you please try following rules. This will take anything in REQUEST_URI starting.
RewriteEngine ON
RewriteCond %{QUERY_STRING} ^$
RewriteCond %{THE_REQUEST} /([^/]*)/([^/]*)/([^/]*)/([^/]*)/?\s
RewriteRule ^(.*) /%1?username=%2&profile=%3&data=%4 [NE,L,NC]
OR(either use above or following one) in case you want to match users in URI then run rules then try following.
RewriteEngine ON
RewriteCond %{QUERY_STRING} ^$
RewriteCond %{THE_REQUEST} /users/([^/]*)/([^/]*)/([^/]*)/?\s
RewriteRule ^(.*) /users?username=%1&profile=%2&data=%3 [NE,L,NC]
Explanation: Adding detailed explanation for above.
RewriteEngine ON: Enabling RewriteEngine here to enable mod rule writing.
RewriteCond %{QUERY_STRING} ^$: Checking condition if query string is NULL then go further in rules.
RewriteCond %{THE_REQUEST} /users/([^/]*)/([^/]*)/([^/]*)/?\s: Matching regex in THE_REQUEST from /users to till spaces and capturing 3 groups values into back references to be used later.
RewriteRule ^(.*) /users?username=%1&profile=%2&data=%3 [NE,L,NC]: Using url rewrite to change URI to as per OP's request which has back references values in it.

htaccess redirect rule from www.domain.com/?page=news to www.domain.com/news

i need to redirect the URL as
www.domain.com/?page=news --> www.domain.com/news
Here my htaccess file:
Options -Multiviews
RewriteEngine On
RewriteBase /
# Force search engines to use www.domain.com
RewriteCond %{HTTP_HOST} !^www\.domain\.com$
RewriteRule ^(.*) http://www.domain.com/$1 [R=301,L]
# Specify search friendly URLs
RewriteRule ^http://www\.domain\.com/news/$ /http://www.domain.com/?page=news [L]
Please suggest me the exact rule to use in .htaccess file.
Thanks in advance.
Your 2nd rule is not correct as you can't match domain name in RewriteRule pattern. That pattern only matches REQUEST_URI without domain name and query string.
Your 2nd rule should be like this:
RewriteCond %{THE_REQUEST} \s/+\?page=([^&\s]+) [NC]
RewriteRule ^ /%1? [R=301,L,NE]
RewriteCond %{REQUEST_FILENAME} -d [OR]
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule ^ - [L]
# Specify search friendly URLs
RewriteCond %{QUERY_STRING} !(^|&)page=[^&]+
RewriteRule ^([^/]+)/?$ /?page=$1 [L,NC,QSA]

Use mod_rewrite to take part of the subdomain and append it to the url

Is it possible to use mod_rewrite to take part of the subdomain from url and append it to the url?
This is the current url, where i have multiple subdomains one for each customer:
customername.subdomain.domain.co.uk
which I am going to point to a new server and new site. The new url format is:
http://domain/login/customername
as all customer are now all under one site.
So what i trying to do is use mod_rewrite to take the whatever before .subdomain and put it at the end of https://domain/login/customername
This is what i have got so far:
RewriteEngine on
RewriteBase /
RewriteCond %{HTTP_HOST} ^([a-z0-9]+).subdomain.domain(.*)$ [NC]
RewriteCond %{REQUEST_URI} $1/
RewriteRule ^(.*)$ https://domain/login/$1 [L]
RewriteEngine on
RewriteBase /
RewriteCond %{HTTP_HOST} ^([a-z0-9-]+).subdomain.domain(.*)$ [NC]
RewriteRule .* https://domain/login/%1 [L]
Trick is: %1 is match $1 from previous line...

htaccess: redirect old domain and all pages to a new domain

I know that there is a lot of examples on Stackoverflow but I still miss something.
I'm trying to redirect http://old.domain.com/fr/ to http://brand.new-domain.com/fr/ with the following rules, but that doesn't work:
# Enable Rewrite Engine
RewriteEngine On
RewriteBase /
# Add a trailing slash to paths without an extension
RewriteCond %{REQUEST_METHOD} !=POST
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} !(\.[a-zA-Z0-9]{1,5}|/)$
RewriteRule ^(.*)$ $1/ [L,R=301]
# Redirect domain
Options +FollowSymLinks
RewriteCond %{HTTP_HOST} ^old.domain.com [OR]
RewriteCond %{HTTP_HOST} ^other-old.domain.com [NC]
RewriteRule ^(.*)$ http://brand.new-domain.com/$1 [r=301,L]
# Remove index.php
# Uses the "exclude method"
# http://expressionengine.com/wiki/Remove_index.php_From_URLs/#Exclude_List_Method
# This method seems to work best for us, you might also use the include method.
# http://expressionengine.com/wiki/Remove_index.php_From_URLs/#Include_List_Method
# Exclude root files
RewriteCond $1 !^(index\.php) [NC]
# Exclude EE folders
RewriteCond $1 !^(assets|ee-admin|images|templates|themes|fr|nl)/ [NC]
# Exclude user created folders
RewriteCond $1 !^(assets|css|img|js|swf|uploads)/ [NC]
# Exlude favico, robots, ipad icon
RewriteCond $1 !^(favicon\.ico|robots\.txt|pple-touch-icon\.png) [NC]
# Remove index.php
RewriteCond %{QUERY_STRING} !^(ACT=.*)$ [NC]
RewriteCond %{QUERY_STRING} !^(URL=.*)$ [NC]
RewriteRule ^(.*)$ /index.php?/$1 [L]
It correctly redirect when I call the root URL, but not when I call a page. What am I doing wrong?
Thanks in advance!

When writing mod_rewrite rules, the rules get applied in the order that they appear.
To redirect an old domain to a new domain, you'll want that rule to be first in your .htaccess or httpd.conf file — all other rules should appear after it.
If you only want to redirect a certain directory, the following rule will do so, while allowing the rest of the site to function normally:
<IfModule mod_rewrite.c>
RewriteEngine On
# Redirect Only Matching Directories
RewriteCond %{REQUEST_URI} ^/(fr|fr/.*)$
RewriteRule ^(.*)$ http://brand.new-domain.com/fr/$1 [R=301,L]
</IfModule>
If you want to redirect the entire site, the following rule will do so:
<IfModule mod_rewrite.c>
RewriteEngine On
# Redirect Entire Site to New Domain
RewriteCond %{HTTP_HOST} ^old.domain.com$ [OR]
RewriteCond %{HTTP_HOST} ^other-old.domain.com$ [NC]
RewriteRule ^(.*)$ http://brand.new-domain.com/$1 [R=301,L]
</IfModule>
If you care about letting crawlers know your content has moved and want to make the transition as seamless as possible, be sure to keep the 301 Redirect flag in the RewriteRule.
This will ensure that users and search engines are directed to the correct page.
While we're on the subject, as part of the EE 2.2 release, EllisLab now "officially" offers limited technical support for removing index.php from ExpressionEngine URLs.
Simply add or update your code to the following, making sure to consider any rules you may already have in place:
<IfModule mod_rewrite.c>
RewriteEngine On
# Removes index.php
RewriteCond $1 !\.(gif|jpe?g|png)$ [NC]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php/$1 [L]
# If 404s, "No Input File" or every URL returns the same thing
# make it /index.php?/$1 above (add the question mark)
</IfModule>
Try to use the following ruke as the first one:
# Redirect domain
Options +FollowSymLinks
RewriteCond %{HTTP_HOST} ^old.domain.com [OR]
RewriteCond %{HTTP_HOST} ^other-old.domain.com [NC]
RewriteRule ^(.*)$ http://brand.new-domain.com/$1 [R=301,L]
Also mind the upper case R with is the short form for the lower case redirect.
Have you tried using mod_alias simple redirect instructions (a core module that you have), before trying the hacky-mod-rewrite thing?
I would do a VirtualHost with ServerName old.domain.com and in this VH I would add this rule:
Redirect /fr http://brand.new-domain.com/fr
from doc:
Then any request beginning with URL-Path will return a redirect request to the client at the location of the target URL. Additional path information beyond the matched URL-Path will be appended to the target URL.
So get a separate VirtualHost for brand.new-domain.com (with ServerName brand.new-domain.com) and in this one do not set the Redirect Rule.
If you still want to handle the 2 domains in the same VirtualHost then you'll have to use mod-rewrite as even RedirectMatch cannot check the request domain on the query.
