using .htaccess to limit access to a directory by a referrer - .htaccess

I would like to forbid access to a specific directory when a certain referrer tries to access anything in it including images and sub-directories. Is there a way to do this within my "global" .htaccess (in public_html) or would I have to create a directory specific one in that directory (eg public_html/phasers ) ?

Deny external access to folder

is there a way to deny outside access to my upload directory ?! I don't want users to access my upload directory : www.example.com/uploads
i used .htaccess in the root of my upload folder however all the links were broken
in my .htaccess :
deny from all
any solution ?
If you wish to disable directory listing, simply place 'Options -Indexes' in your htaccess.
You've applied a 'deny from all', which essentially stops ANYONE from accessing files in the directory to which it applies.
Also make sure that 'AllowOverride All' is specified in the vhost definition, otherwise you are unable to override settings via the htaccess file. That is my understanding anyway.
If you wish to disable access to the upload directory, and control which files in specific users can access, I'd recommend going through a script written in a language such as PHP. A user requests a file from the script, the script looks to see if they're allowed to view the file. IF they are, they file is displayed. IF they aren't then it is not.

how to block access to directories in wamp

I want to block the direct access to directories in the www folder of my wamp server so that no one can directly access the files which are residing there.
Example:
There is a folder in www named "folder". This folder contains a file "page.php" and several images and css files. There is no index file in this folder. Now when the user enters ..../folder/ whole directory will be accessible to user. But I want to hide the directory list from user. But page.php should be accessible when opened through the any other page (via hyperlink)
Please help!
The way you describe it, you probably still want those items to be accessible so that pages referencing those files will still load. You just don't want Apache to list out the files when navigating to that folder.
Apache calls these pages "directory indexes". You can turn it off for a specific folder (and sub folders) by adding to the .htaccess file for that folder an entry:
Options -indexes
More details on the Options directive and .htaccess files here:

allow access to certain directories in htaccess

In htaccess I am blocking directory browsing by using the following code.
# directory browsing
Options All -Indexes
However, I want people to have access to a certain folder, let's say the folder is called pictures, so the folder is at mysite.com/pictures.
How do I give access to that folder/directory, but keep the rest blocked?
Put a .htaccess file into your pictures folder, with this line:
Options Indexes
(or "+Indexes", which is the same.) That should take care of it because child .htaccess files override parents.
From your question it's not clear that you understand the limitations of "Options Indexes". This does not "block" access to a directory; it merely turns off an auto-generated directory listing. Knowing a filename, anyone can still access the resource whether Indexes are enabled or not.

Allow file access from code, but block from browser?

I have my .htaccess file, and I have a folder with config files in there, and they contain sensitive content, e.g. database details etc. What I would like to know is, how can I block access from a browser, but allow them to be accessed via my scripts?
I know that this can be achieved inside the PHP files themselves, but I'd rather use the .htaccess approach where possible.
Is this actually able to be done? I've attempted it before, but in the process of denying access to the file from the browser, it also denied access from the coding.
I have looked into this before, and some of the answers I came across suggested changing the extension to something like .inc, and then denying access to that. However, a couple of issues I have with that is that a) It instantly alerts anyone that can see that filename, for whatever reason, that it is a config file. Also, b) If my denial code breaks, browsers will not parse it as a PHP file, but rather an inc file, meaning it will print the code in the browser.
Basically, can this be done within a .htaccess file, or do I need to put something in the header of every config file?
Put these files outside of your web server's document root.
You can still access them via your server-side scripts, but this ensures no direct access to them from the outside world.
The conventional advice is to place such files "outside of your web server's document root". This is all well and good, but many shared hosting offerings only give write access to your public_html directory.
I use a simple convention: any private content (that is not URI addressable) is prefixed by an underscore or in a directory that's name is prefixed with an underscore (eg. _private or _include). I then include this rewrite rule in my DOCROOT .htaccess file:
# if a forbidden directory or file name (starting with a . or /)
# then raise 404 Fatal return
RewriteRule (^|/)[_.] - [F]
Remember that you'll need to prefix with a RewriteEngine On and/or include this at the top of any .htaccess file with the engine enabled.
Note that the "." prefix picks up files such as .htaccess.
Please use a framework, these kind of issues just doesn't need to exist. If you insist though, write a .htaccess to redirect every request to a single index.php in the root directory, which then have more logic to determine whether or not the request is for a valid file and include them, otherwise generate 404 or 403. If you need performance for static files, then use RewriteCond to exclude specific directories or file type from the index.php check.

Fully securing a directory

What are the different approaches to securing a directory?
including an index page so contents can't be viewed
the problem with this is that people can still access the files if they know the filename they're after
including an htaccess file to deny all
this seems to be the best approach, but is there any case that an htaccess file can be passed by? are there any cases as well where htaccess is not available?
restricting folder access
this is also a nice solution, but the problem is, the folder I'm trying to secure should be viewable and writable by the program.
Are there any other ways that folder security can be done?
Best practice for Apache is to use htaccess to restrict - this only restricts from the webserver - but that should be what you need. You can add authentication into this - but for most needs to you can just deny all acess - which hides the directory completely.
Another method that can also work well with using htaccess to deny direct access would be to use htaccess in your route directory to rewrite urls. This means that a request such as /example/listItems/username/ted can be rewritten as a call to a php or other file such as:
/application/index.php?module=listItems&username=ted
The advantage of doing this is that the webserver does not give out paths to any directories so it is much more difficult for people to hack around looking for directories.
If you want to protect a directory of images you could also use htaccess to redirect to a different directory so that /images/image5.png is actually a call to :
/application/images/image5.png
You could also try not placing your protected directory under your www dir but on other "non www visible" location. If your app needs to read / write data, tell it to do it on the other location. Modify its properties so only the app has the proper rights to do so.
