How to Debug Response.Redirect losing session variable, when upload file
HELP! I have a page where users can enter text and optionally upload an image. To upload the image, the page contains an image file upload usercontrol I created. The control displays the image after loading and stores the image information to the database and creates an image ID. Then the user can submit the entire page which just saves the user's text and the image ID to the database.
In addition, I create a user account for the user and store their new id in a session variable ("LoginID").
When saved, the page does a response.redirect to the next data input page. Excluding the first pag...Response.Redirect with Session Variable vs. Global Variable -- Best Practices?
Hi,I have a simple contact form and when the user presses the submit button an email is sent and I have a response.redirect to "emailSent.aspx" where it says "Your request has been received....etc.". I have the submit button in a try/catch block. What I want to do is a "emailFailed.aspx" where it says "Email problem, etc." but I also want to carry over the ex.message text. I want to pass the ex.error text to the "emailFailed.aspx" page so on pageLoad I can have a label with something like:labelMessage.Text = "There was a problem with your email. The error is " +...Losing Session variables/state?
I'm having regular issues with the ASP.NET 2.0 Sessions. The session variables work fine for the most part. I found, downloaded and installed a Session timeout control which is intended to resend the user to the login page when the session timeout is reached. This does work but I'm not sure how well. The control is installed on various Master Pages.
The problem is that from time to time I get an Object reference not set to an instance of an object error:if (DetailsView1.CurrentMode == DetailsViewMode.ReadOnly)
string session = Session["client_id"].ToString();

I encouter lost session variables trouble when Response.Redirect() to another aspx page. I set 19 Session variables before redirecting. However, the redirected page's session contains only One variable.
The very weir sympton is: If I restart IIS, only for the first IE encounter, the redirected page DOES show all 19 session variables.Once I close IE, any further IE or IE from any other machine's only shows ONE session variable.
I can also reproduce such symptons in VS2005 development environment.
Can someone tell me what I have missed? Thanks!
Here is ...Response.redirect loses session info
Hi - I am running a site which checks available slots on a normal asp.net web site, and then if the user wants to book a slot, redirects them to a page behind SSL where they can enter their Credit Card details.
I use response.redirect to take them to the SSL page (as server.transfer will not show them the padlock etc - so I think this may put people off entering those details) - and I store the information the person was looking for in a session variable.
However, when I response.redirect, the session loses it's information.
Is it correct that sessions only exist in the same applica...Session State variable missing after Redirect
When an error occurs, I set a session variable so that after redirecting to an error page, a detailed explanation can appear. The variable (a string) is gone by the time I reach Page_Load in the target page.
I've checked and it is the same session ID. Any ideas?

I noticed that whenever a session variable is changed...the application knows about it and suddenly restarts session.
My question is does restart "ALL" sessions or only the active sessions for which the variables changed?
Imagine a "multi-user" application all with different states and an administration panel that lets you change session variables. In this case, my question has to do with the question that if Company X changes his session variables, will only Company X's sessions be reset or will all "sessions" be reset? Hope that makes sense.

Hi All, I noticed you responded to a similar post to the problem I am having. Basically
I have built my own URL rewritting app that accepts a url such as
http://www.someserver/com/mypage.aspx?editmode=true an based on this it
does some checks (In On Application_beginrequest or global.asax) to see
if the user should be logged in or not to access the page. If the user
does need to be logged in, it will automatically redirect them to the
login page and request that they log in.The trouble I'm having
is that on the login.aspx when the user logs in and their credential...Session variables vs. Session States
What is the difference and in what situations are they used.
A session state (the state of your session) holds your session variables. If your session state expires (due to inactivity) then you lose your session variables...and any other info stored for that session.
If you need to store USER specific information within a web app, then session variables are one(of several) ways to do it.
Is there any code that you could show that would give an example?
example of what? reading and writing session variables?

I have an application which involves a sign up process where i store details filled in separate screens in session variables
movement between pages is by clicking on a button which redirects user to next page, all because i though button looked neater

Once the data is loaded,I send the DataTable to the session variable. My problem is that when I go to reload the data in the table, it is taking the data from the last user who stored the DataTable instead of from the particular user on their browser.

prb: I have two pages in my app - one on redirect and the other as a new window - that get a new session id from every other page in the app (they both get the same session id) and obviously the session state variables are lost and, therefore, the pages do not look like they should. All pages are within the same domain and virtual directory. 1. a redirect; session variables are lost; session id is different from the previous page; if you click the BACK button you return to the previous page and the session id is the same as before and the session variables are as they should be2. ...
