asp includes with absolute path - asp-classic

is there anyway to do a #include with a file listed as an absolute path?
i am trying to include files from other websites (outsite the root of the sight that wants to include it)
any other suggestions?

You can only include files from your server, these may technically be outside your website if the Allow Parent Paths option is enabled or if you can use a virtual include to point to another virtual directory on your server.
There is no way to include files from websites outside of your server or sites on your server that your application does not have permissions to access.

Another way to go is to create a directory below the root folder of your website, then making that folder a symbolic link to the folder where the file you want to include is located. Now there is no way to create symbolic links in Windows out of the box, you need Microsoft Sysinternals Junction for that.

<!--#include file="c:\boot.ini"-->
There is a setting in IIS for allowing includes to parent paths, check that if the above doesn't work.

You can do it, using XMLHTTP and the VBscript Execute statement.
I wouldn't recommend it though as it creates substantial security risks.
A few links to get you started:

It is a very high security risk, because someone can inject code into your app. Take your precautions.
One tip: the page you need to load from another server needs to have an extension different from .asp because if not the other server is going to send it already executed. It seems clear but I forgot it the first time!

ASP.Net Accessing Server Filesystem

I am having trouble accessing information on the server my website it on. As the website was originally programmed with VB.Net, I cannot change the language without having to completely reboot the website. The way the website and server are configured, I can only use ASP.Net and VB.Net.
I am needing to add a section where they can create folders, edit folder names, and upload pictures and text documents on the server through the public website. I tried using parts of the FileIO, Server, and Http that should have worked, but none of them did. Most of my research is about local files and text documents.
I have not been able to find any information that works. Can someone help me? Thank you.
Firstly, creating a virtual directory in ISS mapped to somewhere on your disk would be a good start. This way you have a separate folder for user data in a folder with write access (make sure IIS has write access to the folder!), and the folder is not affected by website deployments.
Secondly, you might need to resolve absolute path for most of the System.IO.File calls. See How to convert a relative path to an absolute path in a Windows application?, just you will need to convert this code to VB.

is it possible to find hidden files on website?

If I'm hosting a website, say at http://www.example.com, how can I find files that are in the same folder as index.html if I DON'T know the filenames?
So for example, if there are these files in there:
http://www.example.com/test.txt
http://www.example.com/test1.txt
Can anyone see this list of files? If so, how can I hide them, but make each one accessible to someone who knows the names? I don't want to use a password system, if possible.
If you put index.html in that directory, so no files will be listed. If you allow to upload to that directory, so i can upload some php script to list all files in directory. IF you don't know file name, you can try to guess it :)
You can use bruteforce tools such as dirbuster, or you can look at the "/robots.txt" file for some clues on what's on the website.
By the way, you should keep in mind that most of web servers nowadays have rights management implemented, so even if there is such file on the server it may not allow you access to it without authentication.
Some hosting providers provide an option to specify whether directory listings are allowed. If enabled, and a client requests a URL for a folder that does not contain a default HTML file (index.html, default.html, default.aspx, etc), then the web server will serve up an HTML file containing a listing of the files in that folder. It is rare that this option is ever enabled, though.
but you should be accurate while inserting names of files in URL or else you can use pen-test tool which will list out some of the names for free.for attempts ot full listing of files you'll need to be a paid member i guess

How do I get the ASP.NET content relative path

Doing a project between multiple people, and a few components (web app, services app and some others). We will be storing some information inside the Content folder of the web app so it can be accessed directly from the web server with an href, however other components outside of the web app need to access this folder as well, and since we are sharing the project between multiple people using an absolute path is not an option. What options do we have?
EDIT: Trying to explain it a little better.
What i have exactly is, a web project, a "data project" which is just a dll, a "logic" project which is another dll and a services project which is an exe/service.
Both the web project and service project consumes the methods from the logic, and the logic from the data project. Being the last one the responsable for storing data (in a database) and also in the file system.
This "filesystem" path should be configurable, and we are aiming to put it into the content folder of the web project so multimedia files can be accessed directly rather than doing a byte stream.
Now in the web.config(config file of the web app), and app.config(config file of the services app) i could set the absolute path to web/content (the same for both config files) and the data dll would use it without problems. Now the main problem is that we cannot put an absolute path in the config file because each person works on a different computer with obviously different file paths. So if i could just write something like: ~/project/Web/Content rather than C:/myfolder/stuff/blabla/project/web/content in the config files, with ~ resolving the path to the project, this is what i want! Or maybe better ideas about how to share a folder with these apps without adding absolute paths hardcoded somewhere.
What you want to use is:
Server.MapPath("/Content/filepath.ext");
This will give you the absolute path of a file based on it's position within the website, in this case, from the /Content directory.
For a program external to the website, you have a couple options;
The easiest to implement might be a simple configuration value in the external program which points to the directory. My guess is you've already decided that's not ideal, but it may be the quickest way.
Alternatively, there's a Microsoft .NET assembly which gives you easy access to IIS information (I can't recall its name off the top of my head!). You could use this assembly to find the appropriate website, and retrieve its root directory. I'll see if I can find it and get an example, or maybe someone else will see this and post an answer with that information.
Please check the following method "ResolveClientUrl"
MSDN
Use the ResolveClientUrl method to return a URL string suitable for use by the client to access resources on the Web server, such as image files, links to additional pages, and so on.

Interacting With Folders Outside The Root/Web Directory With Dreamweaver (CS5)

Using FileZilla, I can access folders that are outside my web directory. How can I do the same with Dreamweaver so that I can edit the files and automatically save/upload all through Dreamweaver? I currently can only access the web directory.
I know how to include them with PHP, but I would like Dreamweaver to find/access them.
Thank you!
You would have to set the Site Definition (both local and remote) paths to look one level higher than you currently have it. So if the local path is
My Documents/Web Sites/This Site
you would change it to
My Documents/Web Sites/
and if the remote is:
/user/home/domain.com/
change to
/user/home/
The problem you are going to run into is that Dreamweaver doesn't work well when set like this. It assumes the Remote path is the public web root and will create all sorts of files and folders there automatically and DW expects those to be in the public root. Also, things like setting paths to includes and images automatically will start to not work as all paths will start outside of the public web root.
Best to leave it as it is and use an external FTP program to handle the files outside of the web site.
We've bumped up against this situation previously where the desire was to have the PHP include files be moved outside the public HTML directory. JCL1178's answer is absolutely conceptually correct.
The actual implementation was to duplicate the site (under "Manage Sites") and essentially create a separate site for the "includes" directory that would go one level up. So the "Root Directory" setting was normal (in our case "public_html/" in the main site and we removed "public_html/" from the Root Directory setting in the "includes" site, effectively causing the path to go one level up.
Definitely not an ideal situation/workflow, to say the least, as you'll end up with two site definitions for one site (which can cause other issues); but Dreamweaver is what it is. We were working on a project offsite that did not allow for anything other than Dreamweaver to be used, so this is what we came up with to comply.
As an added note: we were only able to implement this solution because the webhosting plan allowed us to get to the root. If you're on a webhosting plan that is strictly limited to the public directory, the whole thing will be DOA.

ImageUrl trying to display an image outside of project root

I am working with two different web sites in asp.net. In the first project i upload some images to a specific folder under the project root and save just the filename in the database, now i am trying to display this images at some page of the second project I know the filename from the database and the image folder as absolute pat but I have not been able to display the image, even thought when looking in firebug the image src is correct src="D:/MyFolder/image.jpg" the image does not display, probably because it is not pointing in the right directory.
I have also tried using Server.MapPath and then my D location but still no success.
I am sure someone has faced the same situation before and was really hoping to get some hint to manage this.
Thank you in advance
I found my solution, strange but i didn't catch it before. Uploaded pictures under a project can always be accessed using the url of the project http://www.yourwebsite.com/images/photo.png now in the second project you can use reference the images using this url and concatenating the file name which i store on database. I think this is the best solution and without changing the code access security which i think can bring other problems with it. Anyway thank you guys.
If you want to display the image that is not in your project (I mean it is present in some other project or some other drive) just create the virtual directory in IIS
Go to "Run", type inetmgr
Right click on your project and add virtual directory
Give alias name and path so that it acts like folder in your project
I don't think you can serve files outside of your application path by default. It's called Code Access Security. You can read up on it here:
http://msdn.microsoft.com/en-us/library/930b76w0.aspx
You can fix this by changing your trust level to High in your web.config:
http://msdn.microsoft.com/en-us/library/tkscy493.aspx
I wouldn't recommend doing this for any site that is externally accessible. In fact, depending on how/where you're hosting your application, this option may be restricted.
You can only "link" to files that exist relative to the same project or are hosted on another site via an absolute URL.
If you want to service files outside the application/website (on disk or in a database) you will need to build a mechanism that gets the file and binary writes it to the browser, setting the MIME type etc. This is best done using an HttpHandler.
