FileExists And Sessions Problem
I simply want to verify the existance of a file on the server,
if the file Exists
do something on the client side
otherwise
Stop executing and reload the main page (login).
To get the response of the FileExists I use a ShowModalWindow from a VBS call. The value returned works fine but only the FIRST time that it is called. Only if I restart the IE I get the correct response from FileExists. It seems a session related problem, infact the modal window has always the same session ID (unless IE is restarted). "Session.abandon" in the modal window code didn'T help.

The following code always displays 'false' in the browser window, which indicates that it's not finding the file.
<%
filename="C:INSTALL.LOG"
Set fso = CreateObject("Scripting.FileSystemObject")
response.write fso.fileExists(filename)
%>
The file definitely exists - why it doesn't work?

Here is my the relevant code:
<%
set fs=Server.CreateObject("Scripting.FileSystemObject")
If fs.FileExists("index.stm") Then
CODE HERE
Else
CODE HERE
End If
%>
The problem is this: fs.FileExists("index.stm") always evaluates to false, even though I'm staring at the file "index.stm" as I type. In fact, I can open the file just fine, using the OpenTextFile() method. Checking to see if the file even exists is the problem.
Anybody have any ideas?

I have been messing with FSO.FileExists for a while and have been looking into its limitations. On our server, we operate our directory in:
d:inetpubwwwrootintranet
and inside that directory is a VIRTUAL DIRECTORY by the name of employeeImages which maps to
otherserverfolder
So saying
d:inetpubwwwrootintranetemployeeImagesfile.jpg
IS the same thing as saying
otherserverfolderfile.jpg
The problem is, that when I set that path to a variable, called strPath and perform the following:
blnExists = FSO.FileExists(strPath)
it KEEPS returning as FALSE. So I had it output strPath. Sure enough it was the URL shown above. I cut and paste that into a window's location bar and boom, I'm taken RIGHT to the image.
So I'm thinking "Ok, FSO is a FILE SYSTEM OBJECT. Maybe it's limitations mean that it can only look at the local filesystem? Maybe it cannot see across a networked device? Maybe it cannot work with virtual directories?" I've done some looking around and cannot find any pages on limitations of FSO.

Dim filesys, test
Set filesys = CreateObject("Scripting.FileSystemObject")
test = filesys.FileExists("probat08at08-dank60apzipap072905.002")
Response.Write(test)
The out put is the word 'False'. However, the file is in that path. This is my first time trying anything over a network, checking files and such.

how to use FileExists to check to see if a file exists on a local server BUT what if I want to check if a file exists on a remote server (webserver)? If I enter "http://domainname/folder/image.jpg" it always returns false.

When a file is local to the ASP application, I can use the following code to
test if the file exists:
Dim strFileName, blnFileExists, objFSO
strFileName = Server.MapPath( "MyFiles est.doc" )
Set objFSO = Server.CreateObject("Scripting.FileSystemObject")
blnFileExists = objFSO.FileExists( strFileName )
Set objFSO = Nothing
But if "MyFiles" resides on another server and I set up a virtual directory
in my ASP app to reference to it (e.g. "MyFiles est.doc" resolves to
server2F$MyFilesest.doc), the code would return False even if the file
exists on the other server.

The jist of what i want is the obj.FileExists (how it checks for a file on the server) for the client machine.
The client will be scanning something that will put a pdf file into a shared folder on their machine (it will be the same path for all clients). I need to get the code* to pull that file so that i can take the data on the pdf.
*Code doesn't have to be ASP. i'm up for ASP, VBScript, Javascript.

I have searched through the threads relating to FileExists, and have not found an answer (I did find one that dealt with using the FileExists method on a remote server, but that's not quite what I need to do.)
The script searches for all pictures in a particular folder on the server. The current script uses m:... as the path. The site will be transferred to a new host, and onto a shared server (so no more m:).
Here's the original snippet: .....

I am going crazy trying to figure out why the FileExists method of the FileSystem object returns false when the file passed to it DOES exist.
The FolderExists method of the same object recognizes the existence of the folder containing the files in question, but FileExists always returns false.

We are planning to set-up a load balanced web environment. Accordingly, we are going to change the session management on our website from the classic ASP Session State and session variables, to a database method.
Does any one have any pointers as to how I might approach this, so that I can have the same sort of functionality the ASP sessions give without having to create database columns for each session variable I wish to create. I am thinking along the lines of some serialised dictionary or something that I can stick in a blob column.

I have session time by default as 20 mints in iis.
I want to that to be increased by 60 mints in my application so that when user save changes after 21st mint the session should not be lost.
Can this be happen without changing the default time in iis since i have many other applications.

I was wanting to know if you could have a function within a session?Example:
Code:
<% Session("Message") = MyFunction() %>
Is that possible? Ok, maybe not "is it possible" but can you use the session message to dictate where the function outputs its data? Here's why I'm asking. I have an online testing app that when a person selects the wrong answer the correct answer (along with a bunch of other stuff) will be displayed on the page.
I'm getting it to display the correct answer and the other information, but the correct answer is at the top of the page screwing up my layout and the other information is doing what it should.

I am using an HTTPS connection and posting to an asp page that does a
redirect based on if the user is authenticated.
However, for some reason after the session is set and the user redirect
the session dies and the user logged out?
Any ideas?
The redirect looks like Response.Redirect "../welcome.asp".

I am using ServerXmlHttp in a client-side component to basically talk back to the Server within a webpage. I would like to be able to cache some information on the server so that when I callback, I do not have to reconstitue everything that I did for the intial request. However, the Sessions are different.
Is there a way to get the ServerXmlHttp session to impersonate the IE client session? Code:

I'm trying to use a couple of Session variables within SSL.
My form submits to the same page and this is at the top of the page.
<%
Session("ShipAhead") = Request.Form("ShipAhead")
Session("Comments") = Request.Form("Comments")
%>
The form fields are populated but the Sessions are empty on my next page.
Am I missing something? Is there a problem with Sessions and SSL?

I've just created a simple form that writes information to an
Access database using ASP. Everything works fine. My question is, would
there be any reason to use the session object other than for tracking
purposes.
Specifically, does a session have any inportance on multiple
users accessing pages and submitting the form inforamtion to the database.
I was curious about errors to the database with multiple users submitting at
the same time to the database. This is a small scale application and not
expected to have large number of hits. As stated I'm new to using ASP and
just wanted to get some input.

I have used SESSIONS on mission critical pages on my site, and if sessions are not enabled / supoorted - these pages will fail. When and why would a session fail? They do not store any info client side,and rely on the server to store session objects in memory, am I correct? Would security settings or privacy controls ever stop sessions working? Which "popular" browsers dont support sessions?

the problem is im not sure how to go about it. i seen sessions mentioned in tutorials but im still ,well, lost basically.

I've got two different sets of ASP scripts on my server. Each set is kept in their own directory. Both sets of scripts use sessions. I want to make sure that the sessions are not accidentially shared between the two sets as they are both different applications.
Right now I'm having a problem when I do a Session.Abandon from one set of scripts it also kills the session for the other set of scripts (I believe they are both using the exact same session). Is there some way I can make sure this doesn't happen?

I have a database add/view/edit/delete page, and you can only get to it by logging in at login.htm (where it checks username & pw and redirects you to the a/v/e/d page.) But if you know the 'Control Panel' address.
you can just type it in and get full access. I figured I must have to check everytime to make sure they logged in. what would be the best way to do this?

I had a contact form set up using CDONTS.NewMail and it worked fine for about two years. I just went in and changed the object to CDO.Message, and adjusted a few of the properties, and while the e-mailing portion of the code still works, none of the session variables on the page work any longer.
I had both the form validation and the message on the "thank you" page set using sessions from the page with the CDO code, but for some reason using CDO cancels the sessions so that Thank You page is blank and the form validation no longer announces which fields need to be completed.
