To Get Direct File Access To Files Within The Web Directories From .NET Application?
Jan 10, 2011
My ASP.NET application logs transactions (both inside AND outside of databases), and therefore needs read/write access to text files within various directories within the root of the website - in ADDITION to the normal database access.
In this scenario, how can I safely allow my ASP.NET application to write data to the web folders? I have a thread-safe DLL that performs the actual work, so I don't believe I need to worry about multiple sessions writing to the log files at the exact same time - assuming my DLL will only be running in a single instance/process that will be shared between numerous ASP.NET instances/processes/threads.
But I'm more concerned about file access permissions. I've heard that ASP.NET applications generally aren't allowed access to the webserver's local file system, and that this may even restrict my DLL from getting the correct file access. Can I grant my application file-access to the web-driectories?

Here is my dilema, on my site i have a WordPress Audio player (http://wpaudioplayer.com/standalone) that plays my mp3's.
It loads the Mp3's in by javascript...example below:
AudioPlayer.embed("audioplayer_7", { soundFile: "/Files/Music/[name of file].mp3" });
This file name is clearly visible in the browser source. Not a problem, however this means that any user can legitimately browse to the file directly and download it.
Now i still need the mp3 player (which is flash) to have access to the file but if a user was to try accessing the file directly, they would not be allowed access to it.
I am not sure how to go about this, i am circling the idea of a httphandler but not sure if this is sufficiant to stop the direct access to the file.

Now,we need to address the following things in that to complete req, 1) If I enter filename_mmddyyyy.txt it should fetch only files having current date in their name in mmddyyyy format.For eg. If I give test_mmddyyyy.txt in txtextension it should return only files with test_10222010.txt and not thee ones with yyyymmdd and all...Right now I am getting all the files created in the current date including the one with ordinary test.txt and also test_20101022.txt .......And the third thing filename.mdd everything is getting passed correctly but it is not fetching the file ..Again test,test_20101022.txt everything comes.It shouldn't be like that it should only fetch files with .mdd (current date)....
In my above code i have two text boxes one for file path and other one for getting extension and also for gettting file names with diff search criteria.....What i do is i should implement file search which is like as mentioned below -
1) it should search for all files if i enter *.*,only jpg if *.jpg, and files like nks.txt if i enter ?
2) if i enter the filename alone without extn it should return me filenames that exist without extension in directories. 3) the final thing is the date in filename where my file will be like filename_mmddyyyy.txt or filename_yyyymmdd.txt or filename.mdd.In first case it should return only files with current date in mmddyyyy format and txt extn....like taht....last case is mdd in extn...
where if i enter filename.123,it sould get me files with jan 23(23 currnt date) and for months greater than 9 it is N for nov ,D for dec and so on.But in m,ytext box i will enter only file.mdd only .and also filename_mmddyyyy.jpg like that....

We have an ASP.NET 3.5 Web application in which we have faced the below issue:
The application is working fine but suddently at one point application URL prompts for the authentication. When we (the support team) checked the server, we were able to identify that the access was denied for some of the main files (like web.config, default page). When we enabled the access the application started working fine.

I need to setup a file handler to route with multiple sub directories something like tihs;
http://localhost/images/7/99/786936215595.jpg
I tried putting this in the global.asax file;
routes.Add(
"ImageRoute",
new Route("covers/{filepath}/{filename}",
new ImageRouteHandler()));
I am using the ImageHandler found in this Question, which works great if you have a single sub-directory (ie '/images/15/786936215595.jpg') but fails when you have multiple directories.
I tried setting up a wildcard and that didnt work (ie 'new Route("covers/{filepath}/*/{filename}"')
This is serving images from a large NAS (think something like 3 million images) so its not like I can just move files around.

I'm working on a website where I need to prevent the direct linking to a few pdf files. I'm using ASP.net 2.0. Is there an easy way in code to do this? or some simple IIS setting?
Right now i'm just using a standard anchor tag to link to the files. i can validate the user on the page containing the anchor tag but that still doesn't stop the user from nabbing the url and passing it on to someone else.

We have a web portal product from which we customize portals from customers. We use the precompiled web app and create a virtual directory (vd) where the customization resides. In addition to this we do some changes web.config in the web app folder. We would obviously like to keep these customizations under TFS source control.
When I try to add the precompiled web app (which I don't want to add to source control), a warning tells me that the vds cannot be added. If I only add the folder that is referenced to by the vd, I lose the references to assemblies in the precompiled web app.
My questions are:
How do I structure a solution for adding IIS (sub application level) virtual directories and still retain the references to assemblies? Is it possible to add other directories/files from the web application level (like App_Theme, web.config etc.) to the solution?
Since we already use Visual Source Safe, we have established a tree structure for each customization project:
Project Root
|
|-Custom Sql
|
|-Custom Portal Files (which is added as a virtual directory)
|
|-Other Customizations
I could probably do a lot of this manually through the source control explorer, but I'd like to have everything done through a solution.
I've followed the instructions using this article: [URL], but this doesn't address the exact problem that I have. Oh, and we are currently using Visual Source Safe for portal customizaton, but are eager to make the move to TFS.

We're having the same setup and receiving the same problem as:
[URL]
Setup
Server 2003 32bit, IIS 6
ASP.NET wild card mapping
A virtual directory mapped to an UNC share serving static images for a CMS in a load balancing environment
My question if it's possible to turn off asp.net from virtual and only serve static files e.g. images in the virtual directory, to avoid the problem with too many open connections?
If it's not possible I'll guess I have to implement a solution like [URL] to server the files from a local disc.
I found a possible solution at [URL] that removes the wild card mapping and makes it possible to turn of execution of asp.net files.

As part of my new user setup, when they sign up for an account I create want to be able to create a directory under a Documents folder for them and then write a web.config file in that folder limiting access to it to the new account. However because they are still in the process they are an unauthenticated user at that point (Forms authentication), and I get an error that they don't have rights to that folder I want to create their sub-folder in. What do I need to set the folder security at to be able to create a folder and a file in that folder from code?

I have certain pages in my application that are designed to be accessed only by redirect from other pages, and not directly(i.e they must get a query string from other page, otherwise there is an exception).
So I want to prevent users from accessing them by typing the URL, but I want them to be available by redirect.

Im using an aspx page as the srcl for an image in the host page to serve a dynamically generated image to the user based on parameters they supply
ie
<img alt="" src="generateimage.aspx" id="imagegen"/></div>
Id like for people only to access the content via default.aspx and not the dynamically generated content generateimage.aspx. Any attempt to browse here directly should be redirected to an error page

I wanna serve my application in ISS to be accessed from many different URL's on my web server.
eg.
http://example.com/test1
http://example.com/test2
Both these URL's get served by the same application.
I do NOT however want to just create new virtual applications to the application, because it stuffs up the user membership roles. The users and their roles must exist accross the two URL's.

In my project I have a website that has 2 sides, the client side and the management side. Everything is completed and works fine.
My idea was to place the management files in a separate folder (mysite.com/admin) the problem is that when I moved the files it could not compile because my admin pages inherit from a class in the app_ folder and looks like it cannot access it.
I wanted to compile the files in the app folder into a DLL but when I try, it gives me a error in the namespace System.Web.UI.Security and the WebControls ns...
How can I access my classes if my files reside in a subfolder within the same application. If I take the files out of the subfolder everything works fine

I am an experienced developer but I am new to web application development. Now I am in charge of developing a new web application and I could really use some input from experienced web developers out there.
I'd like to understand exactly what experienced web developers do in the code-behind pages. At first I thought it was best to have a rule that all the database access and business logic should be performed in classes external to the code-behind pages. My thought was that only logic necessary for the web form would be performed in the code-behind. I still think that all the business logic should be performed in other classes but I'm beginning to think it would be alright if the code-behind had access to the database to query it directly rather than having to call other classes to receive a dataset or collection back.
