For example,on website www.A.com,I use native client filesystem,and save a File named file1.txt. And on website www.B.com, i access the same pexe by using CORS.But the website www.B.com create its own file.Not the same one on website www.A.com. And on my local computer, I find out in the \Google\Chrome\User Data\Default\File System directory, there are two directories named 001 and 002, obviously, they are created by www.A.com and www.B.com.I want to know how to share file between www.A.com and www.B.com
As you've found, the Pepper Filesystem (which is equivalent to the JavaScript DOMFilesystem) is per-origin to the module embedder, not the origin of the pexe. There is no way direct way to share the file.
One possible workaround is to embed your pexe using an iframe. That way it would always use the filesystem origin of the iframe.

I know it's been asked and I have read the posts and Googled this all day. Still nowhere near something that works. Using an .aspx page, I need to upload a .pdf file to a specific website. I'm doing development using VS2017 and VB.Net. The app will run on different websites. It needs to upload client files to a specific different website and path. Also, the file name of the uploaded file will not be the same as the local source file. Creating the new name is no problem.
Let's say a local file must be uploaded to a website at https://www.appfileserver.co.za/pdfdocs, but I'm on https://www.myownsite.com. So, when using FileUpload1.SaveAs(rootedpath) the path that goes in there must be the rooted path to the target. What would the rooted path look like for the example I provided?
FYI, I know the IP addresses, http paths and anything else I need to know because I control those sites. It would be great to do an FTP upload. I have done this many times from desktop apps. Unfortunately I'd need the full path to the local file. It seems there is no way a web page is allowed to get that full path, so FTP upload is out - or is there a way?
After battling for two days trying to FTP upload from website to website (which is not possible because server firewalls block this), I finally solved it. The solution was a simple one. I deployed the upload .aspx file on the target server then embedded that in an iframe on the client machine apps. The files are then uploaded one time to the right place. Simple and 100% effective. Hopefully somebody see's this and understands it - so as to avoid the troubles I had.
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.
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
I have set up 2 drupal instances pointing 2 codebase with a common database
www.abc.com points to folder /var/www/abcfolder
mywww.abc.com points to folder /var/www/mywwwabcfolder
The content is uploaded via mywww.abc.com and www.abc.com is used for general viewing. I have used domain access module where mywww.abc.com is an alais to mywww.abc.com
I want that all the files that are uploaded should be maintained in a common folder i.e. in /var/abcfolder/public/sites/all/files for both urls
I tried changing the file system path via admin/file-system to ../../abcfolder/public/sites/default/files since the path should be relative to the drupal installation folder. However on uploading a file, I get a file not found error.
Any help to resolve this issue would be appreciated?
Should I change the htaccess file in any one of the codebase? If yes, what should the change be?

Loveleen
How about trying this:
Store the files in /var/www/abcfolder/sites/default/files. Create a symbolic link from /var/www/mywwwabcfolder/sites/default/files to /var/www/abcfolder/sites/default/files
Look up symbolic links in linux if you don't know what they are. If you're using windows you can still do symbolic links but they are more complicated.
[BTW I am not sure why you are doing this complicated setup. Reconsider using domain access unless you really need to. Is it necessary to have two sites like this? ]
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.
