.htaccess for CodeIgniter - .htaccess

My CodeIgniter structure :
public/
application/
system/
I don't want anyone to access http://exampble.com/public, allow only the application to access the resource. I tries to create the file .htaccess in directory with the content 'Deny from all', so the user can't access this directory. But my application can't access as well.
How can I solve this problem?
Please give me any idea. Thanks.

From its name, it appears that you're using the 'public' directory to store relevant images and css for your site.
If that is the case, then there's no way you can prevent users from accessing it, unless you don't want to serve images or display styling for your website.
You may however enable what's called hot-link protection which will check for the referrer for each request (not very secure, but thought it might help you out).

How to prevent website being grabbed by IDM( or anyother webstie grabber)?Is there any way to prevent it?

Using website grabbers whole website with folder structure can be downloaded.
Is there any way to prevent this?
If so,how?
The only way to protect a websites markup is not to publish it. If you want your users to see something they need to get the HTML markup and the images, that should be displayed. And therefore the files need to be accessible. And if your files are accessible every user/bot/crawler/grabber can save these files.
The best way is to put a few files like the index page in the main directory and call the other sub pages in it. If using php then you may do the following.
Say keep the index.php in the main folder and keep the homepage.php in a directory called includes and use the homepage in the index.php via include function in php.
Now add a .htaccess file to the includes folder which must contain
"deny from all"
This way users can use the page but will not have direct access to the files. So will be for the grabber.

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 restrict access to views in Codeigniter?

Using Codeigniter I want to make my home.php restricted to only registered users but when I try following
http://127.0.0.1/CodeIgniter_2.1.4/application/views/home.php
I get access to home.php(which is in views).
I thought that CI has some restriction for this type of request but its not.So now how can I solve this.
Should I do this in .htaccess?
OR
I should add php code at the top of home.php which will check for valid session data etc.
http://ellislab.com/codeigniter/user-guide/installation/
For the best security, both the system and any application folders
should be placed above web root so that they are not directly
accessible via a browser. By default, .htaccess files are included in
each folder to help prevent direct access, but it is best to remove
them from public access entirely in case the web server configuration
changes or doesn't abide by the .htaccess.
In your application folder make .htaccess with this:
Deny from all

codeigniter controlled access to a url/folder

I am stuck at the situation where I want the url, which contains a folder having some files (html, swf etc.), to be accessible after I validate the user.
For example.
The url to access is:
A - http://mysite.com/files/version/1/file.swf
And this above url is accessible from the link,
B - http://mysite.com/view/1
I have implemented a way to hide the URL A from a normal user but if the user somehow is a semi-techie person then he can know the swf file location from firebug or other tools. So, to make the access-to-file secure what should I do?
If a user somehow knows the first url(A) and then enters it in browser, i have to check if the user is logged-in and if validation is done it lets the url A to be loaded.
Since, in CI, the controller names cannot be named same as the folders in the root directory, in this case i cannot have a controller called “files”. So, the only option left to make this secure access to url work is to use htaccess rule/cond. If this is the only option, then how can it be achieved by htaccess and if not, then what other options do i have.
Will the codeigniter's URI Routes work because when i tried like this:
$route[‘files/version/1/(:any)’] = “view/$1”;
and it doesnt work, maybe because there is no controller/function/param as files/versions/1 ...
looking for quick help. Thanks
There isn't a sure-fire way to do it without, for example, using .htpasswd.
One thing you could implement is sort of "Security by Obscurity". In that case you could redirect all requests to a file to the URL http://mysite.com/view/file-id and then instead of loading the requested file directly, you would load a .php template with the appropriate headers - be it an image, a flash file or anything else.
But it really depends on how the files are going to be managed, since every file will need an entry in the database and you would have to output different headers for different types of files. And if someone still manages to guess the path to the file, it will be directly accessible.

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.
