Rewrite this URL with parameter - .htaccess

I am having problems understanding the rewriting rules. Basically what I am trying to do is change this:
http://domain.com/Intern/guangjian/gallery/?page=admin_login
Into this:
http://domain.com/Intern/guangjian/gallery/admin_login
I keep getting 500 Internal Server Error when I applied various rules to my .htaccess file. Please help. Currently I have the below:
RewriteEngine ON
RewriteCond %{QUERY_STRING} ^(\w+)=(\w+)$
RewriteRule ^/%2
I admit I don't really understand what all the symbols mean.

The symbols are converting the characters into a sequence of bytes in a specific set using character encoding
Example
Original URL.
Eg. http://flickr.com/users.php?id=username&page=2
Rewriting Friendly URL.
Eg. http://flickr.com/username/2
//First Parameter
RewriteEngine On
RewriteRule ^([a-zA-Z0-9_-]+)$ users.php?user=$1
RewriteRule ^([a-zA-Z0-9_-]+)/$ users.php?user=$1
//Second Parameter
RewriteEngine On
RewriteRule ^([a-zA-Z0-9_-]+)/([0-9]+)$ users.php?user=$1&page=$2
RewriteRule ^([a-zA-Z0-9_-]+)/([0-9]+)/$ users.php?user=$1&page=$2

Place this code in /Intern/guangjian/gallery/.htaccess file:
RewriteEngine On
RewriteBase /Intern/guangjian/gallery/
RewriteCond %{THE_REQUEST} /\?page=([^\s&]+) [NC]
RewriteRule ^ %1? [R=302,L]
RewriteRule ^([^/.]+)/?$ ?page=$1 [L,QSA]

Rewrite Rule syntax is: RewriteRule Pattern Substitution [flags].
This means only the flags (L, NC, R, etc...) are optional, the pattern to match and the substitution parts are mandatory. But you only specified one, which is why you are getting a 500 Internal Server Error.
You don't need RewriteCond. Try this:
RewriteEngine ON
RewriteRule ^(.*)\?(\w+)=(\w+)$ $1/$3
You are getting everything up to the ?, and then attaching the value of page, or whatever argument of the query string, to the url. This of course only works when you have only one argument in the query string, the regex won't match in other case.

htaccess redirect if parameter exists not working

I'm trying to rewrite any URL if a special parameter exists.
So that this happens:
From: www.example.com/somepage/someother/?entryValue=somevalue
To: www.example.com/somepage/someother/?product=test&special=12345ls&linkSource=website
I tried to following, but it doesnt work as expected:
This code adds var/www/* instead of the link
www.example.com/var/www/web6/htdocs/example.com/index.php/*
RewriteCond %{QUERY_STRING} (^|&)entryValue=somevalue
RewriteRule ^(.*)$ $1/?product=test&special=12345ls&linkSource=website [L,R]
This code removes the path:
RewriteCond %{QUERY_STRING} (^|&)entryValue=somevalue
RewriteRule ^(.*)$ /?product=test&special=12345ls&linkSource=website [L,R]
How can I make it work?
RewriteCond %{QUERY_STRING} (^|&)entryValue=somevalue
RewriteRule ^(.*)$ $1/?product=test&special=12345ls&linkSource=website [L,R]
You need to include a slash prefix at the start of the substitution string. Like this:
RewriteRule ^(.*)$ /$1/?product=test&special=12345ls&linkSource=website [L,R]
Without the slash prefix (the URL-path matched by the RewriteRule pattern does not include a slash prefix) it is seen as relative and the directory-prefix (ie. /var/www/...) will be added back and result in the malformed redirect you are seeing.
UPDATE:
but this ends up with "index.php" and the path is lost
You've put the directive in the wrong place and have a conflict. The order of the mod_rewrite directives is important.
Generally, external redirects like this need to go near the top of the .htaccess file, before any internal rewrites (like a front-controller).

How do I create dynamic friendly urls for a query string?

So currently I have URLs that looks like this:
http://localhost/?v=register
http://localhost/?v=profile&u=thatgerhard
I want the above to look like this:
http://localhost/register/ (without trailing /)
http://localhost/profile/thatgerhard/ (without trailing /)
I spent a ton of time trying to get this to work even though it seems like it should be a simple fix.
This is what I have atm:
RewriteBase /
RewriteEngine On
RewriteRule ^((.)*)$ /?v=$1&p=$
I would ideally like this to be dynamic so that if you do ?v=foo it will automatically do /foo/ without adding "foo" to the htaccess file.
Any help or direction will be greatly appreciated. :)
You should use RewriteCond Directive and RewriteCond backreferences. The %1 backreference matches the query string parameter v, the %2 backreference matches the query string parameter u. The RewriteRule redirects the request permanently and discard the query string entirely.
RewriteCond %{QUERY_STRING} ^v=([^&]*)$ [NC]
RewriteRule ^/?$ /%1/? [R=301,L]
RewriteCond %{QUERY_STRING} ^v=([^&]*)&u=([^&]*)$ [NC]
RewriteRule ^/?$ /%1/%2/? [R=301,L]

Htaccess redirect with parameter?

I'm trying to do a .htaccess redirect with a parameter but it's not working. Seems like my regex are also wrong. :(
Original URL 1: http://www.example.com/?team=john-doe
Original URL 2: http://www.example.com/?team
Target URL: http://www.example.com/company/
I tried:
RewriteEngine on
RewriteCond %{QUERY_STRING} team=john-doe
RewriteRule /company/ [L,R=301]
Any help would be much appreciated.
Found a generator that works perfectly:
https://donatstudios.com/RewriteRule_Generator
# 301 --- http://www.example.com/?team=john-doe => http://www.example.com/company/
RewriteCond %{QUERY_STRING} (^|&)team\=john\-doe($|&)
RewriteRule ^$ /company/? [L,R=301]
Your RewriteRule is malformed, you are missing a pattern (first argument). Try something like:
RewriteEngine on
RewriteCond %{QUERY_STRING} ^team(?:=john-doe)?
RewriteRule ^$ /company/? [R=301,L]
The RewriteRule pattern ^$ matches requests for the domain root. The ? on the end of the RewriteRule substitution strips the query string from the redirected URL (on Apache 2.4+ you can use the QSD flag instead).
The CondPattern ^team(?:=john-doe)? matches either "team=john-doe" (URL#1) or "team" (URL#2) at the start of the query string. The (?: part just makes it non-capturing.
You will need to clear your browser cache before testing.

Remove variable from base URL with htaccess

I've been trying to rewrite a URL such as
www.somesite.com/?x=372
into a url
www.somesite.com/
My current code does not seem to work
RewriteEngine On
RewriteCond %{QUERY_STRING} x=(.*)
RewriteRule http://www.somesite.com/ [R=301,L]
I've looked up countless ways of trying to do it with htaccess and still no success.
If you simply want to redirect a client to remove the query string (everything after the ? in the URL), then you can try this:
RewriteEngine On
RewriteCond %{QUERY_STRING} x=(.*)
RewriteRule ^ http://www.somesite.com/? [R=301,L]
You've got most of it right, it seems, but your rule needs to have a match, and your target (the http://www.somesite.com/) needs a ? at the end so that any query string before the rewrite won't get appended.
In Apache 2.4 or newer you can use the QSD query string discard flag:
RewriteEngine On
RewriteCond %{QUERY_STRING} x=(.*)
RewriteRule .* http://www.somesite.com/ [R=301,L,QSD]

htaccess - rewrite rule to get end of url

I have a url which ends with a certain variable string, and was erroneously generated and indexed unfortunately.
Example:
http://domain.com/anything-in-between/?var=xyz-abc-abc-abc
How can I redirect to main site (kill it), by detecting 'abc-abc-abc' using htaccess?
Why wouldn't this work and what would be the best solution:
RewriteCond %{REQUEST_URI} abc-abc-abc
RewriteRule .* index.php
You want to use the query string as claesv suggests but you need to then kill the query string
RewriteEngine On
RewriteBase /
RewriteCond %{QUERY_STRING} \bvar=.*?abc-abc-abc$
RewriteRule ^ index.php? [L]
This will do it silently (i.e. in the server as an internal redirect and not involving the browser). You can't use 301s reliably to trim query strings.
Something along the lines of:
RewriteCond %{QUERY_STRING} ^var=.*abc-abc-abc$
RewriteRule ^.*$ http://domain.com/ [R=301,L]
