How To Access Cache When No HttpContext.Current Is Available

Dec 15 10 at 8:25

During Application_End() in Global.aspx, HttpContext.Current is null. I still want to be able to access cache - it's in memory, so want to see if I can reference it somehow to save bits to disk.

Question - is there a way to reference cache in memory somehow when HttpContext.Current is null?

Perhaps I could create a global static variable that would store pointer to cache that I could update on HTTP requests (pseudo: "static <pointer X>" = HttpRequest.Current) and retrieve a reference to cache through that pointer in Application_End()?

Is there a better way to access Cache in memory when there is no Http Request is made?

Access The HttpContext And Store Into A Local Variable?

I'm trying to access the HttpContext and store into a local variable (HttpContext ctx;) but am getting compile error, indicating I'm missing a directive. But I'm using the System.Web directive, which is the name space HttpContext is stored in.

Wcf - How To Access Authorization Web Service As A JavaScript File

Jul 15 10 at 15:16

A WCF web service with the right class and method attributes can be accessed as a JavaScript file in a script tag. That is:

<script type=".." src="http://someserver/someservice.wcs/js"></script>

Is it possible to do the same thing with System.Web.ApplicationServices.AuthenticationService?

I'm creating a PhoneGap application developed in static HTML/JavaScript, so I cannot use the script manager.

MVC :: Access HTTPContext And Session From Custom Base Controller Class?

Jan 13, 2010 03:12 PM

I built a base controller class inherits from Controller class to add some custom behavior to all controllers which will inherit from this base class.

My issue is when I try to access HTTPContext and Session objects in my custom base class, they are always null.

Am I doing something wrong or need missing something?

My custom base class definition:

public class ApplicationControllerBase : Controller

controllers classes definition:

public class HomeController : ApplicationControllerBase

using ASP.NET MVC 1, .NET 3.5.


It seems the issue is I try to access HTTPContext in the constructor while HTTPContext is not ready yet, I tried it in the OnActionExecuted event handler and it works fine.

My question is what is the best place to access Session object in my custom controller class, that will guarantee executing my code with all controllers.

C# - JavaScript PageMethods Call Loosing HttpContext.Current State?

Dec 29 10 at 23:24

I am using JavaScript's PageMethod functionality where I am invoking a PageMethod which works like a gem. However I am having an issue in accessing the HttpContext's state which returns me a value "SYSTEM" for


which is not the actual current User Name.

I know there are couple options like storing HttpContext.Current in a Session or saving Context's state in some other custom container but given a web farm environment I am assuming that this will not work as expected.

Here is the code I am working on with

function MyFunction(){

here is the signature of the server method

public static void MyPageMethod()
// gives me "SYSTEM"
var user = HttpContext.Current.User.Identity.Name;

Also if I use the above code to access user name in OnLoad event of the page then it works fine and returns me the CurrentUserName.

I am trying to get the above code to work in an ASP.NET Webform... :)

So I am wondering if there is a way to access the current actual user in page methods without making use of sessions.

C# - Workaround For HttpContext.HideRequestResponse Being Internal? Detect If HttpContext.Request Is Really Available?

Apr 9 10 at 17:23

We're migrating an application to use IIS7 integrated mode. In library code that is designed to work either within the context of an HTTP request or not, we commonly have code like this:

if (HttpContext.Current != null &&
HttpContext.Current.Request != null) {
// do something with HttpContext.Current.Request
} else {
// do equivalent thing without HttpContext..

But in IIS7 integrated mode the check for HttpContext.Current.Request throws an exception whenever this code is called from Application_Start.

protected void Application_Start(object sender, EventArgs e)

Results in:

System.Web.HttpException: Request is not available in this context

How can I detect whether the request is really available without wrapping these calls in an exception handler and taking action based on whether an exception is generated or not.

Looking at HttpContext in Reflector I see it has an internal bool HideRequestResponse field but it's internal so I can only get to it with reflection and that's fragile. Is there a more official/approved way to determine if it's ok to call HttpContext.Request?

This blog post about the subject says not to use HttpContext, but how, in generic library code, can you determine if it's ok to use HttpContext?


I'm using the work-around mentioned there which is to use Application_BeginRequest and an initialized field to only initialize once as part of BeginRequest, but that has to be done in every calling application whereas I'd prefer to make the library code more robust and handle this situation regardless of where it's called from.

C# - Retrieving Local Resource Values Correctly: GetGlobalResourceObject Or Control?

Oct 25 10 at 16:00

While developing I've seen a couple different ways to get local resources values from the resx files. Which one is considered the best practice?

Using the GetGlobalResourceObject method:

<a id="myLink" href="#"><%= GetGlobalResourceObject("Filter","Diary")%></a>

Or using a control and setting the value directly in the resx.

C# - Determine The Physical Path Of A File Without An HttpContext?

I have some processes that run without an HttpContext in an ASP.NET MVC web application. This process needs to be able to determine the physical path to the Contents directory of the application for reading/writing data. But, since it is without an HttpContext, I don't get to use fancy things like Server.MapPath and such.

Web Forms :: How To Import Httpcontext.current Into VB Class File

Apr 28, 2005 01:49 PM

From my code behind files I can set session variables just by typing something like:

session("whatever") = True

However, I have a VB class file called Engine.vb where I'm trying to do the same thing, but it's not working. To get it to work, I have to type something like:

HttpContext.Current.Session("whatever") = True

Is there a way that I can import all of HttpContext.Current so I don't have to type HttpContext.Current everytime. Why does this even happen here if it doesn't happen in the code behind files?

C# - HttpContext.Current.Response Write File After Download Manager Starts?

I'm trying to create a ZIP file on the fly which might contain a few thousands of pictures.


My question:

Is there a way to initiate the download (let the download manager on client side popup), and then start writing on the stream?

I monitored w3wp.exe (IIS) process, and it seems that the data is being written on memory instead of Stream.

When w3wp.exe memory usage riches a certain number, it releases the memory and nothing happens (no download).

C# - Application_End() Cannot Access Cache Through HttpContext.Current.Cache

Dec 12 10 at 1:37

I want to be able to maintain certain objects between application restarts.

To do that, I want to write specific cached items out to disk in Global.asax Application_End() function and re-load them back on Application_Start().

I currently have a cache helper class, which uses the following method to return the cached value:

return HttpContext.Current.Cache[key];

Problem: during Application_End(), HttpContext.Current is null since there is no web request (it's an automated cleanup procedure) - therefore, I cannot access .Cache[] to retrieve any of the items to save to disk.

Question: how can I access the cache items during Application_End()?

Relationship Between HttpContext.Request.Cookies And HttpContext.Response.Cookies

Nov 23 10 at 16:41

I have been experimenting with code that will clear all of the cookies in an HttpContext.Response.Initially, I used this:

DateTime cookieExpires = DateTime.Now.AddDays(-1);
for (int i = 0; i < HttpContext.Request.Cookies.Count; i++)
new HttpCookie(HttpContext.Request.Cookies[i].Name, null) { Expires = cookieExpires });

this will error with an OutOfMemoryException because the for loop never exits - each time you add a cookie to the Response, it also gets added to the `Request.

Difference Between ControllerContext.HttpContext.Session And HttpContext.Current.Session

Nov 23 10 at 14:36

i'm using an example in which i can fake the session.It's for use in a unittest of a mvc controller.In the test i create a controller and then i do this:

FakeHttpContext httpctx = new FakeHttpContext(null,null,null,null,mSessionItems );
ControllerContext ctx2 = new ControllerContext(httpctx,new RouteData(), target);

here mSessionItems is my session and target is my instance of a controller,and indeed, when i'm in a controller reading this.ControllerContext.HttpContext.Session, i have a session, great!but.... i also read the session outside the controller, and there i use HttpContext.Current.Session, and that is null (or actualy, the HttpContext.Current is null).
