View 1 RepliesI was so proud because I researched saving files and figured out how to extract the file name from what might be the full path. However, this doesn't work as I had expected. I still get the exception!
Here's the function that saves the file:
protected string SaveFile(HttpPostedFile file)
{
string savePath = Server.MapPath("~/Articles/");
string fileName = Path.GetFileName(article.FileName);
savePath += DateTime.Now.ToString();
savePath += " _ ";
savePath += fileName;
article.SaveAs(savePath);
return DateTime.Now.ToString() + " _ " + fileName;
}

I have introduced site wide exception handling on my site to catch unexpected errors. The event handler sends a message to me when such an exception occurs. But the problem is that any clicks on my site will cause an exception to be thrown with the message: "This is an invalid webresource request."
I googled for an answer and only found a couple of references to 1. setting a fixed machinekey (which for some reason didn't work for me, I got an error saying that the virtual directory wasn't set in IIS, and as far as I know I'm not using IIS at all, I'm using the local development environment and then deploy to a web host) or 2. using a robots.txt file to stop robots from accessing the axd files, but that doesn't help either because it's not robots that cause the problem, anyone clicking around on the page will cause this error. how to solve this problem properly? For now I have handled it by catching and ignoring this particular error by the text in the error message, which works but I would rather fix it so that this error doesn't occur at all.

View 2 RepliesI have been struggling with an issue that sounds like it should be quite common but I can't seem to get the thing working no matter how much I research it!
I am using an AJAX file uploader to upload files (up to 100MB) to the webserver and when the user clicks a button to complete navigate to the next page, I then attempt to move the files off the webserver onto a file server on Page_Load. Both servers are WinServer 2003. There just isn't enough space on the webserver to hold all the uploads once we go live with this solution so I have to get the files off the webserver.
Uploading the file and creating a new subdirectory on the webserver (to hold the file) works no problem at all. When I do the file copy to our file server locally on VS2008, again, no problem. However, when I delopy to the live server and try the same thing, the upload happens ok, but the file copy does not. I get an UnauthorizedAccessException. I don't have access to the webserver myself (but can request it if absolutely necessary) and our file server sits within the same domain (Active Directory).
I do not want to use Impersonation at a high level (web.config), so I tried it programmatically for the purposes of the copy file but it did not work. I used one of our general clerical accounts to pass in the credentials and gave full permission to this account on the file server to create/modify files.
Stack Trace:
