Flash file upload.. no access to session variables

Hey guys I'm witting a pretty simple web app, and I wanted to add multiple file upload functionality.  Well after much searching I came across a couple different solutions and for now I'm working with MultiPowUpload from element-it; the setup was quick and simple and seemed to work pretty well.  It is written in flash and when each file is uploaded the contents are sent to an aspx page in the background and the contents are fetched with an HttpPostedFile call.  The problem is when the call is made to that page I'm unable to access any session variables, it's as if they don't exist.  I need these session variables to assign where the uploaded files are saved.  I'm not quite sure why this is happening, I'm thinking it's a flash limitation.


I've tried a couple different solutions, like putting most of the code in a C# script and read a div element which is dynamically set while I still have access to session variables, but this didn't work.  I'm really pretty lost.  I'm considering storing session variables on the DB, but I've never really done this before.


I'm wondering if there is an AJAXian solution to my issue here.  Does anyone have any advice for me?

The problem is a bug in Flash Player, which doesn't send the needed cookies. Use cookieless sessions, or find another way to provide the data you need. DB-based sessions won't help, since they rely on the same identifying mechanism as standard sessions.

Awesome, thank you.  I will try cookieless sessions, I forgot about that.

Ok turning on cookieless sessions did fix my issue with flash, but now I'm having a whole new issue all together with my AJAX calls.  I'm really lost on where to go with this it's really nasty.  None of my AJAX calls are working, not just my login; they are all failing with the same here, here is the error:

Exception... "Component returned failure code: 0x80040111 (NS_ERROR_NOT_AVAILABLE) [nsIXMLHttpRequest.status]" nsresult: "0x80040111 (NS_ERROR_NOT_AVAILABLE)" location: "JS frame :: http://localhost:2800/mixr2/ScriptResource.axd?d=9IiolU8Akxdiyb5VVargKnHiv-dxjVuIxEEP30jgJ-C-hARS7G3eO5GLDuLA8FqtFXdYelLIqBQ_dJ35q9xvwLmDzLyGnKYC-EUgy8i6QfI1&t=633466580523334880 :: Sys$Net$XMLHttpExecutor$get_statusCode :: line 4166" data: no]
return this._xmlHttpRequest.status;
Here is my Javascript, it fails right before it hits PageMethods:
1    function CallLogin(src,dest)
2    {   
3        $('errorContainer').hide();
4        inputValues[0] = document.getElementById(src[0]).value;
5        inputValues[1] = document.getElementById(src[1]).value;   
6        Effect.Appear('throbberContainer', { duration: 0 }); 
7        PageMethods.AJAXLogin(inputValues, CallLoginSuccess, CallFailed, dest);
8    }

 Here is my code behind, everything was working with using cookie sessions:


1    [WebMethod(EnableSession = true)]
2        public static string AJAXLogin(string[] loginValues)
3        {
4            clsUser theUser = new clsUser();
5            theUser.UserPass = loginValues[1];
6            theUser.UserEmail = loginValues[0];
7            if(theUser.UserError != null)
8            {
9                return theUser.UserError.ErrorUserText;
10           }
11           clsUser newUser = new clsUser();
12           newUser = theUser.validateUser();
13           if(theUser.UserError != null)
14           {
15               return theUser.UserError.ErrorUserText;
16           }
17           // Had to reset the pw to original text because it's being encrypted
18           newUser.UserPass = loginValues[1];
19           newUser.createUserSession();
20           return null;
21       }

If you have any ideas let me know please.  Thanks!

Controlling Folder/File access with session variables
ASP.NET 2.0 -- Is there a way to control access to a folder based on a session variable? For example, Cold Fusion offers a file called application.cfm. This file is read first each time a request is made for any file within a folder that it resides in. If this application.cfm file resides in "/', then it will be read for every file requested in "/" as well, including subfolders. This way you could have more than 1 application.cfm files. So you could place one in the "/admin" folder let's say, and inside the application.cfm file, code would check a session variable, and redirect out ...
