AJAX Timeout Although Request Is Completing Long Before Timeout Duration
Feb 15, 2010I have an ASP.Net application that makes an AJAX request to retrieve at report. The report can run for a long time so I set the asyncpostbacktimeout in <asp:ScriptManager /> to 600. However, when I try to run the report, if it runs for longer than 90 seconds it fails to come back. I can see in the IIS logs that the POST request succeeded with a 200 status and I can see the time taken is much less than 600.
The web page dutifully waits for the entire 600 seconds before returning with a timeout error:
Error:
Sys.WebForms.PageRequestManagerTimeoutException:
The server request timed out.
Is there any setting I should be checking in IIS? Connection timeout is 900 seconds.

View 1 RepliesHow Long Is Timeout For Session
Apr 6, 2012Here are somethings confused me for session timeout. Below are the list of setting:
1) In app web.config, I set sessionstate timeout = 120
2) In IIS6 of web server,
DefaultAppPool, property, Recycle worker processes(in minutes): 15
Web Sites, property, connection timeout: 120 seconds
So, how long is timeout for session?
Forms Data Controls :: Commandargument Wouldn't Change For Session As Long As I Didn't Refresh The Gridview?
Jan 29, 2010I have a gridview set up as follows:
[Code]....
Now, as you can see I've set up the commandargument, and was expecting to get to that in my code behind file. My code is as follows:
[Code]....
Ok...so far so good, and as long as I'm the only one working on the system it works fine. The problem is if this scenario happens:
* I go to the page and look at the gridview
* Someone else enters a new record into the database, causing the first row to contain a new record (not displayed in my browser)
* I click select.
What happens then is that, for some odd reason, I will get n numbers higher than the one I actually selected (n = num_added -num_removed).
I was under the impression that the commandargument wouldn't change for my session as long as I didn't refresh the gridview...?... There are no ajax or anything else messing with postbacks or viewstate as far as I can see..
Master Pages - Where's The Best Place To Store Custom "User" Object For The Duration Of Session
Jul 6, 2010I have an ASP.NET application that needs to remember some info about a user (and what company they are from) across pages, within a session. I imagine this is a requirement of just about any ASP.NET application of a certain size. I've used a few different approaches over the years. In the past, I've passed around an id in querystring parameters like so: [URL] and then instantiated the object on each page (from the database). Another common way of doing it is storing my objects in session variables:
Session["User"] = currentUser; // store at login
User currentUser = (User)Session["User"]; // retrieve on some other page
which saves a trip to the DB, but I worry about memory used if the User object is complex and the site has many concurrent users. I have recently inherited an application that uses public properties on the master page, like this:
Master.theUser = currentUser; // store at login
User currentUser = Master.theUser; // retrieve on some other page
This saves the cast, and looks more readable to me I think, but I don't know if it's better or worse performance-wise. It also has some logic in the getter where if the private value is null, it tries to get it from the Session variable, though I'm not sure if that's never used (or used every get!?) or what. My latest idea is to use my page class. I have a custom page class derived from the standard System.Web.UI.Page base class. It includes objects like CurrentUser as public properties. This seems to work OK. I like it even better. But I really don't know what's going on under the covers. Can anyone give an opinion on which approach is better and why?
Update: I've done some checking use trace.axd and Trace.Write and it looks like neither the masterpage version nor the custom page class version "remember" the values between pages. The "get" methods have a line of code that checks if the User property is null, and if so, reads it from the session variable. This happens when a page accesses the property (Master.User or the derived class's this.User) for the first time on a given page, then subsequent requests can get the value (without going to the session variable). So thus far the best solution looks something like this:
public class MyPage : System.Web.UI.Page
{
private User user;
public User User
{
get
{
if (user == null)
{
user = (User)HttpContext.Current.Session["CurrentUser"]; //check if session[CurrentUser] is null here and log them out if so?
}
return user;
}
set
{
user = value;
HttpContext.Current.Session["CurrentUser"] = value;
}
}
}
Then on any webpage.aspx.cs, you can do something like this: UsernameTextBox.Text = User.FullName;
Web Forms :: Keep Session Variables Active For Longer Period?
Jun 15, 2013When user log's in with it's emaild and password, I have stored it's email id in session variable as: Session("user"). After logged in, If i leave the page kept opened OR ideal for sometime and after thatt if I select any option from user profile, the session variable get expired and send's me back to login page. I want that if I would create 2 to 3 session variable's it should remain activated for longer period. So that even if page kept ideal for longer period and then if selects any option, the session variable's should not be expired soon.
View 1 RepliesWeb Forms :: Timeout Error Continues On Long - Running Web App Supposedly Already Configured To Accommodate Long
Jun 16, 2010I've developed a web application to accept video file uploads and then pass them to a backend service on an external server. The application runs without error on the visual studio debugging webserver, but once on a production iis 6 or 7 server, yields a timeout error at about a consistent amount of time into handling a large upload. Specifically, it errors in the middle of transferring the video file to the external server, once the application has successfully received it from the client. I'm aware of several timeouts to be configured related to the problem, and have done so. The application's web config has been tested with one or both of the following settings
<system.web>
<httpRuntime executionTimeout="9999999" maxRequestLength="2048000" />
</system.web>
and
<configuration>
<location path="default.aspx"> (the page at issue that's timing out)
<system.web>
<httpRuntime executionTimeout="9999999" maxRequestLength="2048000" />
</system.web>
</location>
</configuration>
And within the initialization of the webrequest made to the external server to send the video received from the client browser:
HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create(url);
httpWebRequest.ContentType = "multipart/form-data; boundary=" + boundary;
httpWebRequest.Method = "POST";
httpWebRequest.Timeout = System.Threading.Timeout.Infinite;
So with the execution time limits on both the webform as a whole and the connection made to the external server, I'm at a loss for what timeout is left unconfigured, or how to determine such, when I continue to get the following error: Unexpected error executing Brightcove Upload:...........................

View 2 RepliesC# - Keep Long Running NHibernate Session Data Consistent?
Sep 20, 2010I have NHibernate sessions cached in the ASP.NET session.
I came across a situation where a user edited an object so it's in their first level cache in the ISession. Another user then edited the same object.
At this point User1 still sees their original version of their edits where as User2 sees the correct state of the object?
What is the correct way to handle this without manually calling session.Refresh(myObj) explicitly for every single object all the time?
I also have a 2nd level cache enabled. For NHibernate Long Session should I just disable the first level cache entirely?
Edit: Adding some more terminology to what I'm looking to achieve from 10.4.1. Long session with automatic versioning the end of this section concludes with
As the ISession is also the (mandatory) first-level cache and contains all loaded objects, we can propably use this strategy only for a few request/response cycles. This is indeed recommended, as the ISession will soon also have stale data.
I'm not sure what kind of documentation this is for it to include both probably and then immediately say the session will have stale data (which is what I'm seeing).

View 3 RepliesSecurity :: Signle Sign On Using Active Directory Federation Services - Session Timeout
Jun 29, 2010I have an ASP.NET application that is using Signle Sign On using Active Directory Federation Services
When the user first logs into the application, Once they are "authenticated", their credentials remain active while their web browser is open.
Now, I want the "authentication" to "timeout" in 60 minutes. This way if they browse to another page after 60 minutes, they are prompted to "re-enter" their credentials again.
I know that in FormsAuthentication, you can "de-authenticate" someone by calling "FormsAuthentication.SignOut();" in the Session_End Event in Global.asax.
Is there anyting like that for ADFS?
