Setting A Session Variable In Global.asax Causes AJAX Errors
Mar 26, 2010
I'm getting a very peculiar problem with my asp.net application, it took me an age to track down but I still don't know what is causing this behaviour.
If I set a session variable in the Application_PreRequestHandlerExecute event, then my external JavaScript files are ignored, and therfore causing a raft of errors. I have simplified the problem below.
E.g.
I have file called JScript.js containing the code:
function myAlert() {
alert("Hi World");
}
And in my Default.aspx file I reference the js with the code:
<script src="JScript.js" type="text/javascript"></script>
And in the body onload event I call the myAlert() function:
<body onload="myAlert()">
And finally in the Global.asax file:
Private Sub Application_PreRequestHandlerExecute(ByVal sender As Object, ByVal e As EventArgs)
HttpContext.Current.Session("myVar") = "MyValue"
End Sub
If you run the Default.aspx file you will see the js function isnt called, however, if you comment out the line of code Global.asax then the external js is called and the function executed when the page loads.

I added the following code to global.asax to load up several session variable when a session starts. I'm assuming that when a page goes to use the variable that I should be
1) checking at the page level that the value is valid not 0 when its not expected to be 0, not a zero-length string when its expected to have a length
2) have code at the page level that sets the values if the values have not been set as when the Session timeout, ideally putting the code in a class derived from Page and then deriving all of my pages from the new class so that the code does not have to be repeated in every page
[Code]....

I know there is a couple answered questions on here regarding "request scoped" globals, but I want to nit-pick on something specifically and maybe squeeze some extra enlightenment out of one or two of you.I have an ASP.NET C# Website and a static Dictionary of objects (loaded from DB once on Application start). Each page request will need to do a lookup in the Dictionary (based on a key derived from the request url/etc) and get the appropriate object.The issue is I'm trying to maximize efficiency by reducing the lookups to the Dictionary per Request. Doing just a single lookup within a Page itself is easy enough and I can pass the object to sub controls, etc too.. but global.asax is separate from the Page and it also needs to use the object (in Application_BeginRequest and Session_Start).
So is doing a Dictionary lookup once in Application_BeginRequest, once (when necessary) in Session_Start and once in the Page negligible speed wise, even if there are many requests coming in every second?I would like it if I could just have a Request scoped global variable that I can easily call upon.. the only one I see available though is HttpContext.Current.Items and that is a Dictionary itself.Am I beingridiculously nit-picky with my concern over efficiency? or will these milliseconds (nanoseconds?) get me in the long run when more and more requests are being made?
PS. I currently only have around 100 objects in the Dictionary although this may increase in the future.

So I handle all exceptions in my project within my Global.asax page. For example, on a random page I could have:
[code]....
So my question is in the Application_Error method, do I need the try/catch block when trying to write to the database? I'm thinking I would in case something goes wrong with the connection, etc. - but is this really necessary? Also, what would I do in the catch block if there is an error? At that point I would be catching the error of logging an error which is confusing in its own right.

I am handling errors in Global.asax. When I encounter an error in certain pages, the Application_Error event fires twice. On the second trip, Server.GetLastError() returns null. I have a simple page where I throw an error in page load. When that page throws an error the code below works fine. I also have a more complex page with an update panel and many controls. When that page throws an error Application_Error fires twice. I suspect the update panel but update panels are always suspect, right?
There are no try/catch blocks on any of my pages I'm testing with. Custom errors in web.config is commented out. Note that logging and busywork in the Application_Error event are commented out. I'm pretty much just doing a respone.redirect. The problem with the the event firing twice is that the response.redirect fails with an error msg stating that headers have already been sent (adding Context.ClearError and Response.Clear does nothing to fix that).

I have custom errors set in the web config file as follows:
<customErrors mode="RemoteOnly" defaultRedirect="GenericError.aspx" />
Fine and dandy... I like that mode="RemoteOnly" facilitates development...
For unhandled exceptions, I have in global.asax:
Sub Application_Error(ByVal sender As Object, ByVal e As EventArgs)
Response.Redirect("GenericError.aspx")
End Sub
However, unhandled exceptions are going to the generic error page instead of the informative yellow screen of death preferred by developers. I can comment out the redirect in global.asax, but then I need to remember to change it for the production environment. Is there a way I can check in Application_Error whether I am remote or not to determine whether to redirect?

I'm wanting to adjust this code to pull the theme name from a database table, instead of just manually assigning a theme in the file. This way a site administrator can set the theme dynamically. If never done this with a global.asax file, so I'm not sure what the best way is to accomplish it?
Here's the code that needs tweaked:
[Code]....
The database table could be "ThemeName" with rows ID & Theme. If performing this in the global.asax file will cause any big performance issues.

I need to set a page (unavailable.htm) whenever any user try to access the website from particular time (i.e 1-2 pm). I am using Application_BeginRequest() to check on the hours and redirecting to unavailable.htm. It does not work because it keeps redirecting endlessly to unavailable.htm. Below is my code :

I have a ASP.NET/C# web application. There is an object instantiated in the Global.asax that I'll call g_objVariable. What I would like to do is reference one of it's properties in the ASP.NET page itself, like this.
The g_objVariable's Prop1 value is: <%=AppNameSpace.Global.g_objVariable.Prop1.ToString()%>
I get it to see the reference, but it keeps telling me that due to it's protection level I can't access it. I have it set to 'internal static'. What would be the least level I could set it to, but still allow the page to access it?

I'm using VS2010 and created a simple asp. web forms application, using Development Server to test it. I try to store user data - queried from sql server - in the session, since I don't want to access database in every request. I'm using the 'Application_AuthenticateRequest' and the 'Session_Start' methods.
First round:
AuthenticateRequest called. The following code ran:
[Code]....
The _current variable is a private static field published through a static property. In the first round the Session is null, and I think it's ok because the Session_Start not called yet. The Session_Start looks like this:
protected void Session_Start(object sender, EventArgs e)
{
Session["EMPLOYEE_DATA"] = EmployeeFactory.Current;
}
In the next round the Session_Start is not called of course but in the AuthenticateRequest I can't access to the session. The HttpContext.Current.Session is null and the this.Session reference throw a HttpException says the "Session state is not available in this context".
However I can access the Session from any of the page_load events but it's a bad practice I think that I put authentication every page_load.

I'm trying to use SESSION in my MVC application.I wrote following line in Global.asax in Application_Start() method file:
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
//uzupełnij zmienne sesyjne
HttpContext.Current.Session["LOCATION_ID"] = 15;
RegisterRoutes(RouteTable.Routes);
}
I also enabled SessionState in Web.config by addind following line:
<sessionState mode="InProc" cookieless="false" timeout="120" />
And when I run the application I'm getting this exception:

My ASP.NET intranet web application uses Windows Authentication, and I would like to record the following details:
1) Windows ID
2) Session Start Time
3) Session Stop Time
4) URL being browsed to (optional)
I've got some basic code setup in "Session_Start" method of the Global.ASAX to log session start times (seen below), but that's it so far. I have the feeling this is a primitive approach and there are "better" ways of doing this. So I really have two questions:
1) Is this the right way to go about doing this? If not what are some other options?
2) If this is the right way, do I just need to drop some code in the "Session_End" method to record the time they exit, and thats a complete solution? Does this method always get called when they close the browser tab they have the site open in, or do they have to close the entire browser (I don't have logout functionality)? Any way users can skip over this session end method (or start for that case)?
Dim connsql As New System.Data.SqlClient.SqlConnection(ConfigurationManager.ConnectionStrings("MyConnectionstring").ConnectionString)
Dim cmdsql As System.Data.SqlClient.SqlCommand = connsql.CreateCommand
cmdsql.CommandText = "BeginUserSession"
cmdsql.CommandType = Data.CommandType.StoredProcedure
Try
cmdsql.Parameters.Add("@windowsid", System.Data.SqlDbType.VarChar, 30, "windowsid")
cmdsql.Parameters("@windowsid").Value = Session("UserInfo").identity.name
If connsql.State <> System.Data.ConnectionState.Open Then connsql.Open()
cmdsql.ExecuteNonQuery()
connsql.Close()
Catch ex As Exception
Finally
If connsql.State <> Data.ConnectionState.Closed Then connsql.Close()
End Try

I want to shift the code to the Session_Start event so that the information is always loaded when the site is accessed. How do I call my custom code from global.asax since its script and not a class.
