Apache choose folder based on url parameter and keep url - apache

I'd like to have a way to access folders on my server based on the name given in the url as a parameter.
Let's say my website is www.site.com
I'd like to access custom folders under the main directory by sending a parameter on the url but without having a redirect changing the url.
So I'd provide the folder in the parameter: www.site.com/dev1
This way people wouldn't have to remember the full url be aware of it.
my base folder as per the vhost is /var/www/developers
the subfolders are dev1, dev2, dev3 and so on.
Under dev1/2/3 there is a folder called Portal.
-/var/www/developers
--/var/www/developers/dev1
----/var/www/developers/dev1/Portal
------/var/www/developers/dev1/website/Portal
my current .htaccess is:
RewriteEngine On
RewriteCond %{DOCUMENT_ROOT}/$1/website/Portal -f
RewriteRule ^([^/]*)/?$ /$1/website/Portal [L]
Whilst it is working, it keeps changing my url to www.site.com/dev1/Portal

That is happening because mod_dir is adding a trailing slash after directory portal.
Have your rule like this by having a trailing slash in your rule:
RewriteEngine On
RewriteCond %{DOCUMENT_ROOT}/$1/website/Portal -d
RewriteRule ^([^/]+)/?$ /$1/website/Portal/ [L]

How can I create a redirect with .htaccess to correct path instead of page acess

I am making a multilingual dynamic site that creates a virtual path per language.
So french pages go to domain.com/fr/ english domain.com/en/page domain.com/fr/some/page but in reality these pages are in the base folder and /fr/ is converted to a query string.
This is all working with the following .htaccess:
RewriteEngine on
DirectorySlash Off # Fixes the issue where a page and folder can have the same name. See https://stackoverflow.com/questions/2017748
# Return 404 if original request is /foo/bar.php
RewriteCond %{THE_REQUEST} "^[^ ]* .*?\.php[? ].*$"
RewriteRule .* - [L,R=404]
# Remove virtual language/locale component
RewriteRule ^(en|fr)/(.*)$ $2?lang=$1 [L,QSA]
RewriteRule ^(en|fr)/$ index.php?lang=$1 [L,QSA]
# Rewrite /foo/bar to /foo/bar.php
RewriteRule ^([^.?]+)$ %{REQUEST_URI}.php [L]
My problem is that some sites (Like a Linkedin post) somehow remove the trailing / in the index page automatically. So if I put a link in my post of domain.com/fr/ somehow they make the link domain.com/fr even if it shows domain.com/fr/ but that 404's as domain.com/fr dosent exist.
So how can I redirect domain.com/fr to domain.com/fr/ or localhost/mypath/fr (There's many sites in my local workstation) to localhost/mypath/fr/.
I tried something like:
RewriteRule ^(.*)/(en|fr)$ $1/$2/ [L,QSA,R=301]
RewriteRule ^(en|fr)$ $1/ [L,QSA,R=301]
But that ended up somehow adding the full real computer path in the url:
localhost/mypath/fr becomes localhost/thepathofthewebserverinmypc/mypath/fr/
I would very much appreciate some help as I have yet to find the right rule.
Thank you
RewriteRule ^(en|fr)$ $1/ [L,QSA,R=301]
You are just missing the slash prefix on the substitution string. Consequently, Apache applies the directory-prefix to the relative URL, which results in the malformed redirect.
For example:
RewriteRule ^(en|fr)$ /$1/ [L,R=301]
The substitution is now a root-relative URL path and Apache just prefixes the scheme + hostname to the external redirect. (The QSA flag is unnecessary here, since any query string is appended by default.)
This needs to go before the existing rewrites (and after the blocking rule for .php requests).
Note that the "internal rewrite" directives are correct to not have the slash prefix.
Aside:
DirectorySlash Off
Note that if you disable the directory slash, you must ensure that auto-generated directory listings (mod_autoindex) are also disabled, otherwise if a directory without a trailing slash is requested then a directory listing will be generated (exposing your file structure), even though there might be a DirectoryIndex document in that directory.
For example, include the following at the top of the .htaccess file:
# Disable auto-generated directory listings (mod_autoindex)
Options -Indexes
UPDATE:
this worked on the production server. As the site is in the server root. Would your know how can I also try and "catch" this on my localhost ? RewriteRule ^(.*)/(en|fr)$ /$1/$2/ [L,R=301] dosent catch but with only RewriteRule ^(en|fr)$ /$1/ [L,R=301] localhost/mypath/fr becomes localhost/fr/
From that I assume the .htaccess file is inside the /mypath subdirectory on your local development server.
The RewriteRule pattern (first argument) matches the URL-path relative to the location of the .htaccess file (so it does not match /mypath). You can then make use of the REQUEST_URI server variable in the substitution that contains the entire (root-relative) URL-path.
For example:
RewriteRule ^(en|fr)$ %{REQUEST_URI}/ [L,R=301]
The REQUEST_URI server variable already includes the slash prefix.
This rule would work OK on both development (in a subdirectory) and in production (root directory), so it should replace the rule above if you need to support both environments with a single .htaccess file.

.htaccess redirect only one level from site root

I need to map some direct requests to a custom script:
somesite.com/getfile/file_name.xxx
somesite.com/getfile/type1/file_name.xxx
somesite.com/getfile/type2/file_name.xxx
somesite.com/getfile/type3/file_name.xxx
To accomplish this task I've created an .htaccess with these rules:
RewriteEngine On
RewriteRule ^getfile/(.*)/(.*) /script_path/getfile/file.php?pn=$2&type=$1 [L,NC]
RewriteRule ^getfile/(.*) /script_path/getfile/file.php?pn=$1 [L,NC]
Everything seems to work fine, but if I call a url like this:
somesite.com/test_path/other/getfile/test.php
this url will be redirected to the file.php script!
I need that only the path that starts with getfile immediatly after the domain name to be sent to the script.
somesite.com/getfile -> need to be redirected
somesite.com/test_path/other/getfile/ -> must not be redirected
site folder structure
/
|_www
|_serverRootFolder (the .htaccess file here, this is the apache serverRoot is www.somesite.com/)
|_script_path
The (.*)/(.*) are going to match as far to the right as they can. To match only the ones immediately after the domain, instead of (.*) which is anything, use ([^/]+) which means "not-slash" so it will only go to the next slash. I also added $ on the end, to say there is nothing else following these.
RewriteRule ^getfile/([^/]+)/([^/]+)$ /script_path/getfile/file.php?pn=$2&type=$1 [L,NC]
RewriteRule ^getfile/([^/]+)$ /script_path/getfile/file.php?pn=$1 [L,NC]

How to do a mod_rewrite redirection to relative URL

I am trying to achieve a basic URL redirection for pretty-URLs, and due to images, CSS etc. also residing in the same path I need to make sure that if the URL is accessed without a trailing slash, it is added automatically.
This works fine if I put the absolute URL like this:
RewriteRule ^myParentDir/([A-Z0-9_-]+)$ http://www.mydomain.com/myParentDir/$1/ [R,nc,L]
But if I change this to a relative URL, so that I don't have to change it each time I move things in folders, this simply doesn't work.
These are what I tried and all do not work, or redirect me to the actual internal directory path of the server like /public_html/... :
RewriteRule ^myParentDir/([A-Z0-9_-]+)$ ./myParentDir/$1/ [R,nc,L]
RewriteRule ^myParentDir/([A-Z0-9_-]+)$ myParentDir/$1/ [R,nc,L]
What is the right way to do a URL redirection so that if the user enters something like:
http://www.mydomain.com/somedir/myVirtualParentDir/myVirtualSubdir
he gets redirected to (via HTTP 301 or 302):
http://www.mydomain.com/somedir/myVirtualParentDir/myVirtualSubdir/
Thanks.
EDIT: Adding some more details because it does not seem to be clear.
Lets say I am implementing a gallery, and I want to have pretty URLs using mod_rewrite.
So, I would like to have URLs as follows:
http://www.mydomain.com/somedir/galleries/cats
which shows thumbnails of cats, while:
http://www.mydomain.com/somedir/galleries/cats/persian
which shows one image from the thumbnails of all cats, named persian.
So in actual fact the physical directory structure and rewriting would be as follows:
http://www.domain.com/somedir/gallery.php?category=cats&image=persian
So what I want to do is put a .htaccess file in /somedir which catches all requests made to /galleries and depending on the virtual subdirectories following it, use them as placeholders in the rewriting, with 2 rewrite rules:
RewriteRule ^galleries/(A-Z0-9_-]+)/$ ./gallery.php?category=$1 [nc]
RewriteRule ^galleries/(A-Z0-9_-]+)/+([A-Z0-9_-]+)$ ./gallery.php?category=$1&image=$2 [nc]
Now the problem is that the gallery script in fact needs some CSS, Javascript and Images, located at http://www.domain.com/somedir/css, http://www.domain.com/somedir/js, and http://www.domain.com/somedir/images respectively.
I don't want to hardcode any absolute URLs, so the CSS, JS and Images will be referred to using relative URLs, (./css, ./js, ./images etc.). So I can do rewriting URLs as follows:
RewriteRule ^galleries/[A-Z0-9_-]+/css/(.*)$ ./css/$1 [nc]
The problem is that since http://www.domain.com/somedir/galleries/cats is a virtual directory, the above only works if the user types:
http://www.domain.com/somedir/gallaries/cats/
If the user omits the trailing slash mod_dir will not add it because in actual fact this directory does not actually exist.
If I put a redirect rewrite with the absolute URL it works:
RewriteRule ^galleries/([A-Z0-9_-]+)$ http://www.mydomain.com/subdir/galleries/$1/ [R,nc,L]
But I don't want to have the URL prefix hardcoded because I want to be able to put this on whatever domain I want in whatever subdir I want, so I tried this:
RewriteRule ^galleries/([A-Z0-9_-]+)$ galleries/$1/ [R,nc,L]
But instead it redirects to:
http://www.mydomain.com/home/myaccount/public_html/subdir/galleries/theRest
which obviously is not what I want.
EDIT: Further clarifications
The solution I am looking for is to avoid hardcoding the domain name or folder paths in .htaccess. I am looking for a solution where if I package the .htaccess with the rest of the scripts and resources, wherever the user unzips it on his web server it works out of the box. All works like that apart from this trailing slash issue.
So any solution which involves hardcoding the parent directory or the webserver's path in .htaccess in any way is not what I am looking for.
Here's a solution straight from the Apache Documentation (under "Trailing Slash Problem"):
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^(.+[^/])$ $1/ [R]
Here's a solution that tests the REQUEST_URI for a trailing slash, then adds it:
RewriteCond %{REQUEST_URI} !(/$|\.)
RewriteRule (.+) http://www.example.com/$1/ [R=301,L]
Here's another solution that allows you to exempt certain REQUEST_URI patterns:
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} !example.php
RewriteCond %{REQUEST_URI} !(.*)/$
RewriteRule ^(.*)$ http://domain.com/$1/ [L,R=301]
Hope these help. :)
This rule should add a trailing slash to any URL which is not a real file/directory (which is, I believe, what you need since Apache usually does the redirect automatically for existing directories).
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+[^/])$ $1/ [L,R=301]
Edit:
In order to prevent Apache from appending the path relative to the document root, you have to use RewriteBase. So, for instance, in the folder meant to be your application's root, you add the following, which overrides the physical path:
RewriteBase /
This might work:
RewriteRule ^myParentDir/[A-Z0-9_-]+$ %{REQUEST_URI}/ [NS,L,R=301]
However, I'm not sure why you think you need this at all. Just make your CSS / JS / image file rewrite rule look something like this:
RewriteRule ^galleries/([A-Za-z0-9_-]+/)*(css|js|images)/(.*)$ ./$2/$3
and everything should work just fine regardless of whether the browser requests /somedir/galleries/css/whatever.css or /somedir/galleries/cats/css/whatever.css or even /somedir/galleries/cats/persian/calico/css/whatever.css.
Ps. One problem with this rule is that it prevents you from having any galleries names "css", "js" or "images". You might want to fix that by naming those virtual directories something like ".css", ".js" and ".images", or using some other naming scheme that doesn't conflict with valid gallery names.
I'm not sure I complelty understand your problem.
The trailing slash redirection is done automatically on most Apache installation because of mod_dir module (99% of chance you'have the mod_dir module).
You may need to add:
DirectorySlash On
But it's the default value.
So. If you access foo/bar and bar is not a file in foo directory but a subdirectory then mod_dir performs the redirection to foo/bar/.
The only thing I known that could break this is the Option Multiviews which is maybe trying to fin a bar.php, bar.php, bar.a-mime-extension-knwon-by-apache in the directory. So you could try to add:
Option -Multiviews
And remove all rewriteRules. If you do not get this default Apache behavior you'll maybe have to look at mod-rewrite, but it's like using a nuclear bomb to kill a spider. Nuclear bombs may get quite touchy to use well.
EDIT:
For the trailing slash problem with mod-rewrite you can check this documentation howto, stating this should work:
RewriteEngine on
RewriteBase /myParentDir/
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^(.+[^/])$ $1/ [R]

.htaccess how to substitute urls

How can I substitute URLs of a web application in a sub folder as installed on root.
e.g. need to map
example.com/index.php
to
example.com/new/index.php
I do not want redirection but url rewrite to exempt folder name.
Help me to learn and define rules.
You can use the following rule to rewrite any request that’s URL path (without path prefix) does not start with new/:
RewriteCond $1 !^new/
RewriteRule ^(.*)$ new/$1
This will also work in .htaccess files other than in the document root directory.
But as you want to use this rule in the .htaccess file in the document root directory, you could also use REQUEST_URI:
RewriteRule !^new/ new%{REQUEST_URI}
The first line matches all requests not matching /new/... and prefixes it with a new before it.
RewriteCond %{REQUEST_URI} !^/new/
RewriteRule ^(.*)$ new/$1
Request: http://example.com/index.php
Maps to: [document root]/new/index.php

How do I hide actual directories using mod_rewrite?

I am hosting a couple of domains of the same wordpress installation, now I'd like to have a per-domain folder for some various files I need to put up there.
Essentially I want to map like this:
URL Path
webbfarbror.se/f/* _files/webbfarbror.se/*
grapefrukt.com/f/* _files/grapefrukt.com/*
This little snippet does the job nicely and the RewriteCond let's me enable and disable this on a per domain basis.
ReWriteCond %{HTTP_HOST} webbfarbror.se
ReWriteRule ^f/(.*)$ _files/%{HTTP_HOST}/$1 [L]
However, a file at say, http://grapefrukt.com/f/awesome.jpg is also accessible at it's "real" URL http://grapefrukt.com/_files/grapefrukt.com/awesome.jpg
All my attempts result in infinite redirects back and forth.
How do I disable access through the latter URL?
You can examine the original request as it was sent to the server, which is available as %{THE_REQUEST}. Checking for the /_files/ prefix indicates that the request was of the latter type, and you can then redirect to the appropriate format:
RewriteCond %{THE_REQUEST} ^[A-Z]+\s/_files/
RewriteRule ^_files/[^/]+/(.*)$ http://%{HTTP_HOST}/f/$1 [R=301,L]
