Relationship Between HttpContext.Request.Cookies And HttpContext.Response.Cookies
Nov 23, 2010I 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++)
{
HttpContext.Response.Cookies.Add(
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.
HttpContext Class And Response Property?
Feb 21, 2011I have question about HttpContext class (http://msdn.microsoft.com/en-us/library/system.web.httpcontext.aspx). This class has Responseproperty (http://msdn.microsoft.com/en-us/library/system.web.httpcontext.response.aspx). But I don't understand, why Response property hasHttpResponse return value, not HttpContext (this is HttpContext, not HttpResponse property).So, why there is:

How To Use Httpcontext.response.transmitfile Or Other Function To Download A File From A Network?
Feb 25, 2010Does anyone know how to use httpcontext.response.transmitfile or any other httpcontext function to download a file from a network drive instead of local drive? When I tried to use context.Response.TransmitFile(DownloadPath) to download files, the DownloadPath has to be local drive. If it's a network drive, the download failed.

Dec 17, 2010I'm trying to create a ZIP file on the fly which might contain a few thousands of pictures.
[code]....
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# - Workaround For HttpContext.HideRequestResponse Being Internal? Detect If HttpContext.Request Is Really Available?
Apr 9, 2010We'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)
{
SomeLibrary.DoSomethingWithHttpContextCurrentDetection();
}
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?
http://mvolo.com/blogs/serverside/archive/2007/11/10/Integrated-mode-Request-is-not-available-in-this-context-in-Application_5F00_Start.aspx
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.
Difference Between ControllerContext.HttpContext.Session And HttpContext.Current.Session
Nov 23, 2010i'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).

MVC :: Response.End And Filters / Can Get Response.End() To Work When Called
Nov 19, 2010I have a static method that I use to control REST styled HTTP codes when my mvc application encounters an exception.
The method looks like:
[Code]....
This is static becuase then I can call it within an action or inside a filter. The problem I am having is that when I call RaiseException inside a filter, it stills goes into the requested action. Response.End() doesn't seem to have any effect. Any clues on how I can get Response.End() to work when called?

View 5 RepliesC# - Using Response.Filter With Response.TransmitFile?
Aug 10, 2010I'm using Response.Filter in order to implement stream compression in accordance with HTTP Request Header Accept-Encoding
Here's the important stuff:
if (AcceptEncoding.Contains("deflate") || AcceptEncoding == "*")
{
HttpApp.Response.Filter = new DeflateStream(PreviousOutputStream, CompressionMode.Compress);
HttpApp.Response.AppendHeader("Content-Encoding", "deflate");
}
By and large this works as intended. However, I'm in a situation where I'm using an ActionResult on an MVC Controller to serve up files to the user agent:
Response.Clear();
Response.Headers["Content-Type"] = contentType;
Response.Headers["Content-Length"] = contentLength;
if (Request.QueryString["dl"] == "1")
{
Response.Headers["Content-Disposition"] = "attachment; filename=" + fileInfo.Name;
}
Response.Flush();
Response.TransmitFile(fileInfo.FullName);
To be more exact, the action method returns new EmptyResult() after the Response.TransmitFile() call. This works exactly as intended without the Response.Filter modification.
In this situation, the response entity reaches the user agent garbled and unintelligible. FireFox's Poster addon shows empty entities or jumbled entities coming back.

View 2 RepliesGetting HttpContext From BackgroundWorker Process?
Aug 19, 2010I have an ASP.NET site and I've been doing some work refactoring code to try to remove some long running processes (in the order of an hour) from the actual http Request by creating a BackgroundWorker and sending the work off to that to process. This was running fine on cutdown tests but when I applied the logic to the real code I found problems accessing Session variables from the code running in the Background Worker. It seems that the HttpContext object that was passed has a null session and if I ask for HttpContext.Current I get null back.
I'm assuming that this is because they are in a different thread and that the session and HttpContext.Current are both reliant on being in the same thread. Is there any way I can get access to the Session from the background worker or am I stuck with finding all the variables I need from session and putting them in an usable data structure and then putting them back in session (if appropriate) afterwards? It obviously complicates the refactor massively if I need to do this so I'd rather not.how I might do this other than BackgroundWorker processes
Creating A Wrapper For HttpContext?
Feb 8, 2011I'm trying to create a SessionManager class which I can use to manage sessions in my MVC applications. For that I'm thinking the best way of doing so is by creating a wrapper class for HttpContext which would then allow me to access HttpContext.Current.Session.
To be honest, I'm not really sure about the whole thing, I just feel it's the logical way of doing so. I also want to create an ISessionManager and ISession interfaces, and then implement them according to my application's needs. For my current project, and for now, I need a InProc session management, but I might need to store session data in MSSQL Server when we decide to expand and use a web farm or a garden. That's why I'm trying to build a sort of an extensible framework right from the start.
Final note, I will be using Microsoft Unity to inject the concrete SessionManager of choice. I believe that's a good way to maintain a certain level of abstraction.
C# - .Net Control.OnInt And HttpContext?
Feb 2, 2011I'm digging around with HttpContext and the OnInit event for a custom control, after realizing that a few checks are not responding in the desired manner.
Within the current context's items collection, I store an object (serialized) that I would like to interrogate once on every post back. The first time the control is rendered, will the items[] be null, it then gets populated somewhere down the line and the user clicks a button to post back data.
Now, within the button submit event, I set the items[key] to null to ensure that on the post back I don't have anything stored, but it always contains a value.
I'm assuming that the OnInit handler has a reference to the previous state, thus 'falsely' assuming that the items[] should contain a value. Is this something to do with the way OnInit works, or am I missing the bigger picture?
