Howdy
I've got a rather strange issue occuring.
I used forms based .NET authentication, although I'm also setting some
session variables when people login.
However, I've found when people use one of my webform pages which includes a
button that pops up a window where you can upload files, if you upload files
in this popup window, it seems to somehow clear out all of the session
variables and the users get logged out. However, if people don't upload
files, then their use of the webform page proceeds as required/expected.
I'm planning to phase out the session variables by upgrading my code,
however I can't understand this problem which seems quite strange and I'd
like to know what the problem is.
Any clues would be greatly appreciated.
Cheers
Matt
If it helps, here is code in question:
The main part of the code behind for the upload page:
private void Page_Load(objec t sender, System.EventArg s e)
{
// Put user code to initialize the page here
if (!IsPostBack) {
pnlUpload.Visib le = true;
pnlUploaded.Vis ible = false;
}
if (IsPostBack) {
pnlUpload.Visib le = false;
pnlUploaded.Vis ible = true;
}
strJobRequestID = Request.QuerySt ring["JobRequest ID"];
btnClose2.Attri butes.Add("oncl ick", "return closeupdate();" );
}
public void UploadFile(obje ct Sender,EventArg s E) { //Event handler for
the upload button
lblFileList.Tex t = "";
if (Request.Files. Count > 0) { //if there are files attached
//Get directory path
string strDirPath = Server.MapPath( ".\\" + "/../../detail/files/" +
strJobRequestID + "/");
//Response.Write( strDirPath);
//if Directory path doesn't exist then create it
if (!Directory.Exi sts(strDirPath) ) {
Directory.Creat eDirectory(strD irPath);
}
//Iterate through the Request.Files collection
for(IntLoop=0; IntLoop<Request .Files.Count; IntLoop++) {
if (Request.Files[IntLoop] !=null) { //Checking for valid file
// Since the FileName gives the entire path we use Substring function
to get the filename (including the file extension).
string StrFileName =
Request.Files[IntLoop].FileName.Subst ring(Request.Fi les[IntLoop].FileName.LastI ndexOf("\\")
+ 1);
string StrFileType = Request.Files[IntLoop].ContentType;
int IntFileSize = Request.Files[IntLoop].ContentLength;
//Check for file length > 0 and Upload if it is
if (IntFileSize > 0) {
//Save the file to the web server
string filePath = (strDirPath + "/" + StrFileName);
Request.Files[IntLoop].SaveAs(filePat h);
lblFileList.Tex t += "<li>" + StrFileName + "</li>";
}
}
}
}
}
Here is the main code for the webform. Notice the "multipart/form-data" -
could that be causing the problem somehow?

Hi Matt,
Looks like your appdomain is recycling.
You may check that using Perfmon and application restrats counter to verify
if your appdomain is recycling.
Also, what is the size of the file which causes the issues? Is it each and
every file which causes the session to recycle??

Hmm, application restarts are 807 and Requests Queued is 54,000!!!!
And the error occurred for 1 file of 1KB too.
Actually seems to be the code below that's causing the problem, which
renames the file upload directory from a temporary name to the ID number of
the job request (because the webform page in question is for logging a job,
and the directory path ID number is not known until the job is logged):
//JOB FILES (if they exist)
//Root directory path for JBS job files
string strDirPath = Server.MapPath( ".\\" + "/../../detail/files/");
//Response.Write( strDirPath+"<br >");
//New Directory path for logged job files
JBSv4.utils.jbs .v4.utils.utils utilsClass1 = new
JBSv4.utils.jbs .v4.utils.utils ();
strLongJobReque stID = utilsClass1.Lon gJobNumber(intJ obRequestID);
string strDirPathJobNo = strDirPath + strLongJobReque stID + "\\";
//Response.Write( strDirPathJobNo +"<br>");
//Directory path used for temporary file storage before JobRequestID
was created
strTempJobReque stID = tbxTempID.Text;
string strDirPathTemp = strDirPath + strTempJobReque stID + "\\";
//Response.Write( strDirPathTemp+ "<br>");
//Rename temporary file storage directory (if it exists) to job number
directory
if (Directory.Exis ts(strDirPathTe mp)) {
Directory.Move( strDirPathTemp, strDirPathJobNo );
}
What do I do?
Thanks again for any more help.

On further investigation, it is this code
if (Directory.Exis ts(strDirPathTe mp)) {
Directory.Move( strDirPathTemp, strDirPathJobNo );
}
causing the problem, and I note that when this code runs (and the user gets
logged out), the counter for application restarts increases by 1.
I'm reading something that makes me think that maybe some virus checking
software is involved in the problem.
Thoughts?

I've noticed that session variables will persist on Mac IE even after all

None of them, however, got a clear explanation that would correspond to my

I'm having a problem and I can't find anything about this anywhere else
out there.
I'm working on a solution that allows the end user to create folders /
upload files to the web server. Some pertinent information is being
stored in a session variable. If a user deletes the folder from the
application, it clears any session variables as if deleting a folder
made a call to Session.Abandon(). This also occurs if I delete the

Hi all,
We have a small problem.
We are running an ASP.NET1.1 application, using IIS6 on server2003, no web
farm, on a single server, using in-proc session state, only using one worker
process.
The problem is that at seemingly random times, some of the session variables
return as if set to nothing.

I have a site with an App_Code folder that has Global.asax.cs and a
file named Upload.cs.
I want to pass Upload.cs a Session variable (username) that is set in
default.aspx.
Setting up a session variable in default.aspx is no problem, but how
do I make it available to Upload.cs? I think it's a matter of
writting code into the following two files: Global.asax.cs, and
obviously, Upload.cs, but how exactly is it done?

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
