Only Serve Static Files From a Specific Directory via Code - asp.net

I am looking for a code based solution to only serving static files from a specified directory using ASP.NET routing rather than specify a HttpHandler in the Web.config.
For example:
I have the following partial directory layout
/
/public
/public/hello.txt
/public/css
/public/css/base.css
/readme.txt
If any files are requested from the /public directory they should be served as-is. If any other static files are requested for example /readme.txt it should be served as a 404. The directory which allows static files to be served from should be easily specified as a string (var publicDir = "public";).
I am looking to do this with little to no configuration required in the Web.config file, and most of it configured in code.

I don't think it would be possible to achieve a solution using a class library. In IIS 6 environment files with .TXT or .JPG extension are served without going through .NET Framework. The only way is changing IIS configuration.
In IIS 7 things are handled differently but I have no idea if it is possible to find a solution that works in all environments or not.
I'll be pleased to hear what others say about this and correct me if i'm worng.

Symfony access assets folder

I have some folders in www/web/ which is the root.
It's the following folder: assets/exports/
And it contains a file export.xsl
When I do in javascript:
window.open('/assets/exports/export.xsl');
I'm going to the following link:
http://mywebsite/assets/exports/export.xsl
But I get a: 404 not found
Is symfony somehow protecting this link?
So, my question is, how can I access this file, so it starts downloading for the visitor?
From Symfony Documentation:
Keep in mind that web/ is a public directory and that anything stored here will be publicly accessible, including all the original asset files (e.g. Sass, LESS and CoffeeScript files).
Make sure you put the files in a proper directory: <symfony_root_dir>/web. See below.
Then accessing the http://mywebsite/assets/exports/export.xsl returns the file's content.
Check also your server configuration, virtual host config and read web server configuration guide from Symfony to see if you configured it properly.

Get Static referenced files with http request in meteor

This can be a silly question but I have had some issues with it. I am trying to implement jwplayer with meteor. Jwplayer will try to get a file based off the url you suggest. So I tried to place a file in localhost:3000/test.mp3. When I tried to hit that url I get just the default site. This would work if I used tomcat. Is there something I can do to get the files relative to meteor directory?
Thanks for your help.
In the /public directory, per the docs:
Lastly, the Meteor server will serve any files under the public directory, just like in a Rails or Django project. This is the place for images, favicon.ico, robots.txt, and anything else.
Meteor hasn't yet implemented server side routing and all directories are ultimately flattened. So for the time being, you can access your file at http://localhost:3000/test.mp3, but that may change in the future.

How might i setup my ASP.NET project to find my files?

edit I do not want to redirect pages, specific files etc. I would like to change the path where images, videos and other media are stored from the root source directory to the directory of my choosing. In this case c:/dev/prjfiles/prjname/public (c:/dev/prjfiles/prjname/ is my working directory) and i except when my html does img src="/pic.png" it will find the image in c:/dev/prjfiles/prjname/publi/pic.png. I need a working solution, i tried looking at how to set virtual directories and etc. I cant figure it out. Thus the bounty. I am generating the html, i am not writing asp:image runat="server" etc i am pulling data from a DB and outputing the html. The part that is still a WIP is the code that handles POST request. The html already exist but i cant have hundreds of files in site.com/here pollution my source directory (c:/dev/trunk/thisprj/thisprj/where my .aspx files are and i do not wish 500 .png/gif/jpg here)
I dont know how asp.net environments are usually set up. I am assuming i have a root path that is not available from the web, a bin/ where i may put my asp.net dll and a public where i stick in any files i want.
I would like to have my project files seperated from everything else. My JS, css and image files are in prjfiles/prjname/public with my sqlite db in prjfiles/prjname/ and extra binaries in prjfiles/prjname/bin.
The problem comes when i run my app and try to load an image. Such as /cssimg/error.png. My project does not find resource in my /public folder and i have no idea how to make it find them. How can i set my project up so it does?
NOTE: I set the working directory path so its at prjfiles/prjname/. In code i write ./bin/extrabin.exe and db.sqlite3 which access the files properly.

EDIT: More info added
As #Murph suggests, your assumptions are incorrect.
IIS takes care of blocking HTTP access to any important files and folders like your *.aspx.cs, and *.cs in the App_Code, any DLLs, anything under the App_Data directory and the web.config.
Content files, such as *.html, *.css, *.js, .gif, .jpg, .png are all served in the normal manner.
In this way, there is no need for a "public" folder.

This is wrong assumption!
You have a root folder, which IS available in public. You set IIS or ASP.NEt Development Server to this folder.
(optional, but always needed) You have a web.config file in this root folder for configuration
You have a bin folder for your assemblies (each page or user control "include" compiles to a class)
(optional) You have App_Data as default folder for file-based DBs and/or other data files (say XML storage, ..)
(optional) You have an App_theme folder for styling and images. Read about ASP.NET themes.
(optional) You can add App_Code folder if you want to add classes to be compiled by the server.
You can create folders for scripts, etc...
Normally for complex logic, etc.. you create in a separate project outside the root and reference the result assembly in the bin folder.
Seriously, you cannot do ASP.NET work without an IDE or a manual. Visual Web Developer 2008 Express IDE is free and http://asp.net has tons of resources for getting started.
I don't know if I got the question right, but maybe you could try the <BASE> HTML tag.
HTML <base> Tag
"Specify a default URL and a default target for all links on a page"
There's a nice and simple example at W3Schools, check it out.
The negative side is that you need to put a <BASE> tag in each page you want.
It sounds like you should be able to create a virtual directory to do what you're asking -- but it's a very non-standard setup.
Keep in mind that IIS will prevent users from downloading DLLs and other project-level files, so you usually don't need to partition them off in a separate layer.
For example, just have a cssimg folder at the top level of your project, and skip the whole public folder thing.
I see where you're coming from. ASP.NET projects are set up a little differently from how you're treating them, but you can make them work like you want.
The root of an ASP.NET project IS publicly accessible. When you created your WebSite within Visual Studio, it created a default.aspx page right on the root. Are you hosting in IIS? If so, it's set up to serve up default.aspx by default. But I digress.
Here's how to make it work like you want (mostly):
Create a WebSite, then right-click the site and add a folder named "prjfiles". Right-click that folder and make another named "public". Create another subfolder of that one called "cssimg".
Now, if you want to use the image you mentioned, you'd reference it like this: "~/prjfiles/public/cssimg/error.png" (pathing starting with the root) or "./cssimg/error.png" if you're coming from a page in the public folder (relative pathing).
Really, though, you're doing too much work. Here's how to make it work with less effort:
Create your WebSite, right-click the project and add a folder called "cssimg".
Treat the root as you would the "public" folder- put your pages right there on the root or in subfolders, as needed. You can reference that same image file like this now: "./cssimg/error.png" (relative) or "~/cssimg/error.png" (start from root)
There's also another way to tell the engine where to look for resources, but it's for your css files. Inside the "head" tag, you can add a "style" element (with type="text/css") and inside that you can add something like this: #import '<%= ResolveUrl("~/prjfiles/public/cssimg/styles.css") %>';
Good luck!
If I correctly understood your problem, you're trying to find files which aren't physically stored on a filesystem folder, or stay on a different folder. You can deal with this problems by implementing a UrlRewrite mechanism.
I suggest you to read URL Rewriting in ASP.NET and, after, to take a look into this implementation: A Complete URL Rewriting Solution for ASP.NET 2.0.
If I understand all this correctly (please comment with any correction) right now all your files are together in the root directory and you use <img src="/img.png" /> and it works.
If this is the case, make another directory in the directory the images are in, say call that directory images and put the image files there. now use <img src="/images/img.png" />.
Done.

Can i put URL rewriting http module in a folder?

I am trying to make a generic URL rewrite methods, and i want it portable so i checked this article: http://weblogs.asp.net/scottgu/archive/2007/02/26/tip-trick-url-rewriting-with-asp-net.aspx which is very nice.
But i want to put all my classes, http modules in one folder, then i can just paste this folder in any asp.net website and edit the web.config to point to this http module, thats it, without the need to add anything in the APP_Code as this article teaching.
My question is is that possible? any conc or better ideas?
The ASP.NET runtime only looks by default in a limited number of folders for code files that it compiles on the fly -- App_Code (and its subfolders) is one of them. If you place code in an arbitrary folder, it won't be found.
The usual approach for what you describe is to build a DLL, and then drop it into the web site's bin folder. You would then have a separate project in Visual Studio for building the DLL. Using a subfolder in App_Code is another possibility.
You could also put your DLL into the GAC, which would make it accessible to all sites on a server.
You always can to compile that code into an assembly (.dll), place it inside your /bin folder and to update your web.config file.

ASP.NET: external custom config file in a virtual directory - how to?

I know that there at least two approaches to leverage the web.config file:
using the configSource attribute which was introduced in .NET 2.0 - here is a good blog entry about it.
The file attribute of the appSettings tag which lets you point to an external file with a relative path. Described in the MSDN documentation on the appSettings element.
Now, my problem is that both approaches work well only for physical paths. But I need to address a config file which is in a virtual directory.
Which other method could I use to put my config resources in a virtual directory?
Note: I want to do it this way, because I have multiple instances of my web application on the same server (and that on many servers). To keep deployment easy and clean, I want to keep one directory for all the files (aspx, ascx, images, css, js etc.) and point the web apps in IIS for different customers (=domains, https etc.) to this single directory. In every IIS web I would have a virtual directory called "custom" which points to a different folder for each web.
Update: I'd like to point out that this virtual directory "custom" is not suited to contain an inherited web.config - that web.config would be valid only for the custom folder which doesn't contain aspx/ascx files.
I have the same scenario and after reading you post I realised that asp.net won't let you do this for various security reasons.
Therefore I turned to the OS to find an equivalent to the Linux soft link function which in turn led me to the Junction utility from sysinternals. This can create a directory that is actually any other directory on that volume and asp.net can't tell the difference and so happy loads the config sections that are not actually in a subdirectory of you website. Works for me :)
Virtual Directories can be set as applications, and you can just place another web.config there.
It will inherit any changes from the parent config, and you can add custom settings in it.
I was looking to do the same thing but it did not work, so I decided to do the opposite, as you know the web.config can be inherited, so I pointed IIS to a folder containing the client config (connection string, file path etc) files and the website files i put them on a virtual directory with the rest of the webconfig (where it load dll and other application files needed)
So basically i can use the website files to multple clients and the clients with their own Database connection string and other specific client settings.
