Context is Null at this point. I am a noob in ASP.NET with regards to Global.asax.cs. This code was written by another developer. EDIT: This is the code with HttpContext...
I have a custom provider for authenticaiton that is HTTP Module-based. IIS authentication and web.config authentication is configure to 'None' and allow anonymous. When I probe for User.Identity.Name in Session_Start, it is empty. However User.Identity.Name works elswhere in the application as expected (returns the current user id). Is it possibly during Session_Start no authentication request has been issued, therefore there is no principal at this moment?
In the website we have several folders, some folders are accessible by anonymous users, others are accessible by members only, some by administrators or a both administrators and members can view this folder. Each folder contains some forms; these forms are based on the role as well. We'd like to add "user.identity" as to authenticate the user based on the user_id from table websit_ users.
However we are not sure , wither we need to specify each and every form, folder or this will be done automatically once authentication is applied. And where do we put the user.identity and what is the exact format of it. Do we include it in our Global.asax after the authentication part?! This is the code in global.asax:
what might be best suited to place in the Application_Start and Session_Start subroutines? I know when each subroutine is called. Application_Start when the first user first accesses the web application. Session_Start when a user opens a session with the application. But what code belongs in each of these subroutines. What should the code in each subroutine do?
This is quite simple. When I press btn1, it sets correctly the Session Key. And this is then the issue arrives: When I press one of these buttons, this is the sequence of what happens:
So, everytime there is a PostBack, even before the Page loads, the session starts and generates a new Id. This way, I loose everything during the PostBack. My Session State configuration:

This is running on VS 2010 + V3.5, on IIS5.1. The Page header configuration is default.
I am developing a small asp.net mvc intranet application for our company. Right now the home page will get the Windows username from the windows logged on user and make a call to our active directory based on that username to get more detailed info about the user (email, ect.) Everything works great on my local Visual Studio 2008 server. But when I deploy all the files to my IIS 6.0 server I get the following:
[NullReferenceException: Object reference not set to an instance of an object.] STPIntranet.MvcApplication.Session_Start() in C:Documents and SettingscsallemiMy DocumentsVisual Studio 2008Projects<ProjectName>Global.asax.cs:50 [TargetInvocationException: Exception has been thrown by the target of an invocation.] System.RuntimeMethodHandle._InvokeMethodFast(Object target, Object[] arguments, SignatureStruct& sig, MethodAttributes methodAttributes, RuntimeTypeHandle typeOwner) +0 System.RuntimeMethodHandle.InvokeMethodFast(Object target, Object[] arguments, Signature sig, MethodAttributes methodAttributes, RuntimeTypeHandle typeOwner) +71 System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture, Boolean skipVisibilityChecks) +350 System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture) +29 System.Web.Util.ArglessEventHandlerProxy.Callback(Object sender, EventArgs e) +42 System.Web.SessionState.SessionStateModule.RaiseOnStart(EventArgs e) +8779824 System.Web.SessionState.SessionStateModule.CompleteAcquireState() +237 System.Web.SessionState.SessionStateModule.BeginAcquireState(Object source, EventArgs e, AsyncCallback cb, Object extraData) +504 System.Web.AsyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +66 System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +155
It is failed in my Global.asax.cs file where I try to populate a custom User object (has a username and email property). In line 50 where the error is occuring I make a call to a class called SecurityUtil to get the username from WindowsIdentity.GetCurrent() and then get the email by making a call into our active directory. I almost want to say that the necessary libraries are not getting added in either my project dll or web.config file because of the null pointer. Also, the error line is point to my local file structure (C:Documents and SettingscsallemiMy DocumentsVisual Studio 2008Projects) and not the file structure residing on my iis 6.0 machine.
I'm using the HttpRunTime.Cache.Add to create a routine that runs every 5 mins to post data out of my app to the main DB, and this works fine. However I also need to import some files from disk in this routine. I have my document directory set up in my web.config as a ~/ relative path and resolve this in normal controller actions using Server.MapPath(string). How can I do this in my Global.asax.cs code -when I try to access it, it throws an error?
I'm creating a Linq to SQL dynamic data web-site. I have created a new project, added a Linq to SQL classes object to my App_Code folder, and dragged the relevant tables from my Server Explorer window onto the dbml designer. I've saved and built my solution. So, I have this in the dbml code file:

I get the following error: The type or namespace name 'DealerClassesDataContext' could not be found.
I am using form authentication in my website. I have a scenario wherein the user is authenticated but the session has timed out. So, i would like to initialize some session variables in Session_Start of Global.asax (First i check if Request.IsAuthenticated=True). For that i required the name of the user who authenticated. On .aspx pages we can get it using Page.User.Identity.Name but how to get it in global.asax page.
FormsAuthentication.SetAuthCookie("myusername", False) server.transfer("somepage.aspx") to open a web page. Context.User.Identity.Name is found to be empty
I am trying to create a httphandler which will intercept a sample pdf file which we have in our website. The httphandler works fine from within my development machine and even my locally published website that if I just try to connect to the test url: [URL] I will get sent to the invalid access page. So pushing it to our IIS6 machine when I try to go to the URL it serves up the PDF document. context.User.Identity.IsAuthenticated is always showing as true. I'm using forms authentication. below is the code I am using as the handler.
public void ProcessRequest(HttpContext context) { if (context.User.Identity.IsAuthenticated) { string SampleURL = context.Request.AppRelativeCurrentExecutionFilePath; context.Response.Buffer = true; context.Response.Clear(); using (FileStream fs = new FileStream(HttpContext.Current.Server.MapPath(SampleURL),FileMode.Open)) { int length = (int)fs.Length; byte[] buffer; using (BinaryReader br = new BinaryReader(fs)) { buffer = br.ReadBytes(length); } context.Response.Clear(); context.Response.Buffer = true; context.Response.ContentType = "application/pdf"; context.Response.BinaryWrite(buffer); context.Response.End(); } } else { context.Response.Redirect( "~/Error/invalid_access.aspx"); }}
in web.config I have the following for form authentication:
To avoid going to the Databse to get the user Id, Id like to append userId to the Context.User.Idenity.name field. This way I can split the returned string to get the UserId without going to the database.
Where can I do this when using the login controls?
What should be done if I want to redirect a user based on their ISO Codes?
And how should I detect a website user's IS Code in the first place? Like I know there are these server variables that we use to detect Client IP and all (HTTP_FORWARDED_FOR, REMOTE_ADDRESS, etc) but information about them on the many sites that I have read has got me confused about what to use. Like some say there can be comma separated IPs returned by HTTP_FORWARDED_X and out of those IPs , one is not sure which is the real IP and which are the proxy addresses. Also, that all the IP addresses in returned can be fake.
How to I fetch the REAL IP Address of a person? Like I only want to know what country a particular person is sitting so I can redirect the user accordingly. Secondly lets say a person is sitting in US then I want the user to be redirected to [URL] If a person is visiting my site from Germany, [URL] is the address that I want the person to be redirected to.Also if DE is the ISO Code then I want my GermanMaster.master page to load and if its US then I want that the USMaster.master should load.
So how do I fetch a user's not fake IP address, redirect a user based on that ISO code and then load a master page according to the ISO Code.
How do I go about it? I haven't ever worked with Global.asax before so clueless how to go about it all.
I need an app pool recycle to be completely transparent to the users of my web app. I use ASP.NET 3.5 MVC 1.
Currently, upon an IIS 7 App Pool recycle all users logged into my web app are kicked out and are required to log back in (Context.User.Identity.IsAuthenticated is set to false). I employ SQL State Server, I use forms authentication and both are configured to use cookies. I was under the impression that .NET and/or IIS handles authentication of cookies.
However, every time the app pool is recycled Context.User.Identity.IsAuthenticated is set to false my users are kicked out and are required to log back in. I can see that the session id remains the same throughout logins, I can also view this session information in the database/state server.
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)?

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.
Is it possible in the global.asax file on session_start to check if a url string exists and it it does insert the string into a sql database? The url would be something link http://www.mysite.com?campaign=january.
I would want to capture the january bit and put that in the database for each visitor that uses that url.
I have a hosting account on DailyRazor.com , i use Global.asax in my project to start a schedule process in Application_Start.When i just publish my website, and upload it, the Application_Start does not Fire, but when i upload the Global.asax to my host it gives an Error but the Applicaiton_Start Event fires up, and then i delete the Global.asax file and everything works.just wondering, What am doing wrong ? or why this meaningless thing happens?
I have a site with multiple domains pointing to it. I wanted to redirect all requests to main domain so I've created a method called RedirectToRealDomain("domain.com") to check and redirect all requests to my preferred domainAt the moment it lives on Session_Start but I am planing to move it to Application_BeginRequest event. As I understand Session_Start only raised when new session started but Application_BeginRequest raised on all requests. RedirectToRealDomain method doesn't do any DB lookups or anything expensive apart from comparing strings.
I am trying to check if the user belongs to someone's friendlist from the database and redirect him accordingly.I am doing this in a routehandler called by Global Asax.I just want to know how to get the username (from the login information) in the route handler class (or Global asax)I used this: string username = HttpContext.Current.User.Identity.Name; and very strangely, its assigning ".aspx" as the username!! ps: i did search for similar question but in vain.
I need replace double slashes in one slash. I am planning do this in Global.asax Application_BeginRequest event. Is it enough? or better do a http module?
UPD Sub Application_BeginRequest(ByVal sender As Object, ByVal e As EventArgs) ' Fires at the beginning of each request
