Get utl parameters / URL rewriting - apache

I'd like to use URL rewriting to have "virtual" subdomains. I already created wildcard DNS entry.
I want subdomain to be added as GET parameter.
Example:
http://mysubdomain.domain.com/index.php
would call:
http://www.domain.com/index.php?subdomain=mysubdomain
and
http://mysubdomain.domain.com/page.php?parameter1=parameter
would call:
http://www.domain.com/page.php?parameter1=parameter&subdomain=mysubdomain
This is my .htaccess file:
RewriteEngine on
RewriteCond %{HTTP_HOST} !^www.domain.com$ [NC]
RewriteCond %{HTTP_HOST} ^(www\.)?([^\.]+).domain.com$ [NC]
RewriteRule ^$ /index.php?subdomain=%2 [L]
RewriteCond %{HTTP_HOST} ^(www\.)?([^\.]+).domain.com$ [NC]
RewriteRule ^([A-Za-z0-9_.]+)$ /$1 [L]
It works but I cannot get subdomain value, when calling other page than index.php, if I call http://subdomain.domain.com/page.php I loose subdomain parameter, I tried:
RewriteCond %{HTTP_HOST} ^(www\.)?([^\.]+).domain.com$ [NC]
RewriteRule ^([A-Za-z0-9_.]+)$ /$1&subdomain=%2 [L]
But I got Internal error.


THis rule:
RewriteRule ^$ /index.php?subdomain=%2 [L]
needs a QSA flag:
RewriteRule ^$ /index.php?subdomain=%2 [L,QSA]
and this rule:
RewriteRule ^([A-Za-z0-9_.]+)$ /$1 [L]
needs the QSA flag and the proper backreference:
RewriteRule ^([A-Za-z0-9_.]+)$ /$1?subdomain=%2 [L,QSA]

.htaccess external & internal rewrite conflict

I'm trying to rewrite a query string to a path, like so:
http://example.com/?p=page1
to
http://example.com/page/page1
The internal redirect works and I can view the page at the second URL but as soon as I try to redirect the first URL to the second, I get a 'Too many redirects' error.
.htaccess:
RewriteCond %{REQUEST_URI} /page/(.*)
RewriteRule page/(.*)$ index.php?p=$1 [L,QSA,NC]
RewriteCond %{QUERY_STRING} ^p=(.*)$ [NC]
RewriteRule (.*) /page/%1? [R=301,L,NE,QSD,NC]
The first two lines are working by themeselves. The addition of the last two lines causes the error.

Your rule is redirecting the uri back it itself that is why you got the redirect error.
You can use %{THE_REQUEST} or %{ENV_REDIRECT_STATUS} variables to avoid Too many redirect error .
RewriteCond %{REQUEST_URI} /page/(.*)
RewriteRule page/(.*)$ index.php?p=$1 [L,QSA,NC]
RewriteCond %{ENV_REDIRECT_STATUS} ^$
RewriteCond %{QUERY_STRING} ^p=(.*)$ [NC]
RewriteRule (.*) /page/%1? [R=301,L,NE,QSD,NC]
or
RewriteCond %{REQUEST_URI} /page/(.*)
RewriteRule page/(.*)$ index.php?p=$1 [L,QSA,NC]
RewriteCond %{THE_REQUEST} /\?p=.+ [NC]
RewriteCond %{QUERY_STRING} ^p=(.*)$ [NC]
RewriteRule (.*) /page/%1? [R=301,L,NE]

htaccess mod_rewrite - Trailing Slash and loop of redirects

Here is my htaccess code:
RewriteEngine On
RewriteRule ^s/(.*)/(.*) /index.php?search=$1&category=$2 [L,QSA]
RewriteCond %{QUERY_STRING} ^search=([A-Za-z0-9\+]+)$
RewriteRule ^(.*)$ /s/%1/? [R=301,L]
RewriteCond %{QUERY_STRING} ^search=([A-Za-z0-9\+]+)&category=([A-Za-z0-9\+]+)$
RewriteRule ^(.*)$ /s/%1/%2/? [R=301,L]
I need to make a rewrite rule like this:
http://mywebsite.com/s/query+term => http://mywebsite.com/?search=query+term
OR if there is a category
http://mywebsite.com/s/query+term/Category => http://mywebsite.com/?search=query+term&category=Category
I need also to redirect all the old urls to the new one.
With this rules all that I can obtain is to have the search term and category name joined togheter. In a nutshell it is as if I had always:
http://mywebsite.com/?search=query+term/Category
If I remove all the conditions (RewriteCond), leaving only the rewrite rule with the addition of a trailing slash:
RewriteEngine On
RewriteRule ^s/(.*)/(.*)/ /index.php?search=$1&category=$2 [L,QSA]
Reaching the url of my interest in a direct way, the whole thing works. But I will not have the redirect..
So I have tried to set a rule like this:
RewriteEngine On
RewriteRule ^s/(.*)/(.*)/ /index.php?search=$1&category=$2 [L,QSA]
RewriteCond %{QUERY_STRING} ^search=([A-Za-z0-9\+]+)$
RewriteRule ^(.*)$ /s/%1/? [R=301,L]
RewriteCond %{QUERY_STRING} ^search=([A-Za-z0-9\+]+)&category=([A-Za-z0-9\+]+)$
RewriteRule ^(.*)$ /s/%1/%2/? [R=301,L]
But with this rule I get just a loop of redirects.

You can use the following rules :
RewriteEngine on
#1--Redirect from "?search=foobar&cat=cat" to "/s/foobar/cat" --#
RewriteCond %{THE_REQUEST} /\?search=([^&]+)&cat=([^\s]+) [NC]
RewriteRule ^ /s/%1/%/%2? [NC,L,R]
#2--Redirect from "/?search=foobar" to "/s/foobar" --#
RewriteCond %{THE_REQUEST} /\?search=([^/\s]+) [NC]
RewriteRule ^ /s/%1? [NC,L,R]
#1--Rewrite "s/foobar/cat" to "/?search=foobar&cat=cat"--#
RewriteRule ^s/([^/]+)/([^/]+)/?$ /?search=$1&$category=$2 [NC,L]
#2--Rewrite "s/foobar" to "/?search=foobar"--#
RewriteRule ^s/([^/]+)/?$ /?search=$1 [NC,L]

.htaccess rewrite path: New query string removes the paths first trailing slash

I have this code to rewrite a path, and then redirect to subdomain's folder:
RewriteEngine On
RewriteBase /
RewriteRule ^category/?$ category.php
RewriteRule ^category/[a-z0-9\-]+\_([A-Z0-9\_]+)/?$ articles.php?id=$1&section=category
RewriteCond %{HTTP_HOST} ^test.(.*)example.com/?$ [NC]
RewriteCond %{REQUEST_URI} !^/\!test/ [NC]
RewriteRule (.*) /!test/$1 [L,NC]
RewriteCond %{HTTP_HOST} ^example\.com$ [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [NE,L,R=301]
The big problem is that typing this in the browser address field and press Enter:
http://test.example.com/category/article-about-something_35436
Ends up in that it changes by itself to:
http://test.example.comcategory/article-about-something_35436
And the browser of course tells you that "Server is not found".
Troubleshooting
I have figured out that this works fine:
http://test.example.com/category
And removing the query string ?id=$1&section=category from the second rewrite rule works. You don't end up on the article of course but on articles.php.
So, anyone know the problem?

Rearrange your rules and keep redirect rules with R flag before other internal rewrite rules:
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^example\.com$ [NC]
RewriteRule ^ http://www.%{HTTP_HOST}%{REQUEST_URI} [NE,L,R=301]
RewriteRule ^category/?$ category.php [L,NC]
RewriteRule ^category/[a-z0-9-]+_([A-Z0-9_]+)/?$ articles.php?id=$1&section=category [L,QSA]
RewriteCond %{HTTP_HOST} ^test\.(.*)example\.com$ [NC]
RewriteCond %{REQUEST_URI} !^/\!test/ [NC]
RewriteRule (.*) /!test/$1 [L,NC]

redirecting file request for subdomain and main site with certain arguments?

I am running wildcard subdomains. the aim of the site is to run a virtual subdomain. what the functionality should be is that when the files
from the main site are called they will be rewritten for the clean URLs. But when i am calling the same files form the subdomain
like xyz.doamin.com/my-file.php then this should be rewritten like it is calling that file with an argument of subdoamin like
domain.com/my-file.php?var=xyz. Currently what i have done for the file call is this
Options +FollowSymLinks
RewriteEngine on
## Redirecting all non-www domains to www.domain.com
RewriteCond %{HTTP_HOST} ^domain.com [NC]
RewriteRule ^(.*)$ http://www.domain.com/$1 [R=301,NC,L]
RewriteCond %{HTTP_HOST} !^www\.domain\.com$ [NC]
RewriteCond %{HTTP_HOST} ^(.*)\.domain\.com$ [NC]
RewriteCond %{QUERY_STRING} ^$
RewriteRule ^(.*)$ http://www.domain.com%{REQUEST_URI}?var=%1 [L]
RewriteCond %{HTTP_HOST} !^www\.domain\.com$ [NC]
RewriteCond %{HTTP_HOST} ^(.*)\.domain\.com$ [NC]
RewriteCond %{QUERY_STRING} !^$
RewriteRule ^(.*)$ http://www.domain.com%{REQUEST_URI}?%{QUERY_STRING}&var=%1 [L]
RewriteCond %{HTTP_HOST} !^www\.domain\.com$ [NC]
RewriteCond %{HTTP_HOST} ^(.*)\.domain\.com$ [NC]
RewriteCond %{QUERY_STRING} ^$
RewriteRule ^(.*)$ http://www.domain.com/index.php?subdomain=%1 [L]
RewriteCond %{HTTP_HOST} !^www\.domain\.com$ [NC]
RewriteCond %{HTTP_HOST} ^(.*)\.domain\.com$ [NC]
RewriteCond %{QUERY_STRING} !^$
RewriteRule ^(.*)$ http://www.domain.com%{REQUEST_URI}?%{QUERY_STRING}&subdomain=%1 [L]
This is throwing a 500 internal error for the file call.

Rule set 4 will overlap with rule set 1 and 2. I suspect this is causing the issue.
So I think all 3 need an extra RewriteCond check on REQUEST_URI.
Really you shouldn't need rule set 4. Just including index.php as a default should do the trick. Unless of course you don't want URL's like http://www.domain.com/?var=xyz, in this case you need rule 4, but you need to split it into 2 - one with a QUERY_STRING and one without, just like rule 1 and 2
Also, isn't %1 from the regex in the rewriteRule itself and not the preceeding rewriteConds? If so then your regex is wrong, because it'll be setting the var= to the entire original URL.
Looking in the error log is a good idea as it will give you the reason for the 500 error.
Edit: Ok, try something like this (not tested)
## Redirecting all non-www domains to www.domain.com
RewriteCond %{HTTP_HOST} ^domain.com [NC]
RewriteRule ^(.*)$ http://www.domain.com/$1 [R=301,L,QSA]
## Redirecting / requests to index.php
# Note: Use the QSA flag for handling with or without query string
RewriteCond %{REQUEST_URI} ^/$
RewriteCond %{HTTP_HOST} !^www\.domain\.com$ [NC]
RewriteCond %{HTTP_HOST} ^(.*)\.domain\.com$ [NC]
RewriteRule ^(.*)$ http://www.domain.com/index.php?var=%1 [L,QSA]
## Redirecting /something requests to index.php
# Note: Use the QSA flag for handling with or without query string
RewriteCond %{REQUEST_URI} ^/.+$
RewriteCond %{HTTP_HOST} !^www\.domain\.com$ [NC]
RewriteCond %{HTTP_HOST} ^(.*)\.domain\.com$ [NC]
RewriteRule ^(.*)$ http://www.domain.com%{REQUEST_URI}?var=%1 [L,QSA]

Redirect not working for complex rewrite rules (.htaccess)

I'm trying to make a redirect from a non-www version of the link to the www one. Its working fine for something like http://mywebsite.com but it fails for a request like http://mywebsite.com/artists/metallica/ or even a complex one. The whole .htaccess file is bellow. Any clues?
Options +FollowSymLinks
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} !(.*).html
RewriteCond %{REQUEST_URI} !(.*)/$
RewriteRule ^(.*)$ http://mywebsite.com/$1/ [L,R=301]
RewriteRule ^artists/([^/-]+)-p([^/]+)/$ /artists.php?l=$1&p=$2 [QSA,L]
RewriteRule ^artists/([^/]+)/$ /artists.php?l=$1 [QSA,L]
RewriteRule ^submit/$ /submit.php [QSA,L]
RewriteRule ^users/$ /users.php [QSA,L]
RewriteCond %{THE_REQUEST} ^.*/index.php
RewriteRule ^(.*)index.php$ http://www.mywebsite.com/$1 [R=301,L]

Try this rule:
RewriteCond %{HTTP_HOST} !^www\.
RewriteCond %{HTTPS}s ^on(s)|
RewriteRule ^ http%1://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
But make sure that you put this rule in front of those rules that just do an internal rewrite. Otherwise an already internally rewritten rule might get redirected externally.
