C# - How To Get The Physical Location Of Web Application Without Using HttpContext.Current
Jun 11, 2010
I've found myself having a requirement to configure log4net based on a file relative to the physical location of the running ASP.NET web application. We like to start the logger as early as possible, so Application_Start seems a proper place. In IIS6, this works fine and has been running for ages, but now we moved to IIS7 and this won't work anymore:
because the HttpContext.Current is not available in many global.asax (Application, Session) events. This is old news, we all know it raises the now infamous Request is not available in this context error. We don't want to move back to Classic Mode.
Now, the question is simple: without using HttpContext, is it possible to find the physical location of the currently running web application instance?
I wanted to understand the behavior of HttpContext.Current.Application during the load balancing. I have read that session can be stored in disk hence can be retrieved from different servers. Is this true for HttpContext.Current.Application also. Does the keydata stored in one machine is accessible in other different machine too?
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.
I have a website say www.abc.com I am giving the users there own mini site with the URLwww.abc.com/website/home.aspx?UID=1
This URL will access to my Home.aspx page located in website folder and display the user information based on UID
I want to register each user with their own domain and redirect the functionality to mywww.abc.com/website/home.aspx?UID=1 page.
For example let's say when user type www.user.com user the site will be redirected to mywww.abc.com/website/home.aspx?UID=1 page but the URL of web browser will not change, user can still seewww.user.com on his web browser.
If User click about us link i.e. www.user.com/aboutus/ the site will be redirected towww.abc.com/website/aboutus.aspx?UID=1 page but the URL of web browser will not change.
I have a website say [URL] I am giving the users there own mini site with the [URL] This URL will access to my Home.aspx page located in website folder and display the user information based on UID. I want to register each user with their own domain and redirect the functionality to my [URL] For example let's say when user type [URL] user the site will be redirected to my [URL] page but the URL of web browser will not change, user can still see [URL] on his web browser. If User click about us link i.e. [URL] the site will be redirected to [URL] page but the URL of web browser will not change. I am using IIS 6 and ASP.net 2.0.
I'm running an Asp.NET MVC 2 app under IIS 6.All pages are behind Windows Integrated Authentication except for some pages that accepts anonymous access.We setup these pages in the web.config with the location element like this
this is an Asp.NET MVC app, the path indicated in the path attribute points to an action method not a physical location.When this was running under IIS 7 integrated mode it was working fine. But when we switched to IIS 6 we get the login prompt even with the pages that are set to accept anonymous users.ow to make IIS 6 authorize anonymous access to non physical paths ?
I've set up IIS7 on my home computer and have written a very basic ASP.NET website to be deployed on this webserver. Everything works great. How do I determine programmatically the physical path (for instance, "C:inetpub_MyWebsite") of the website? I need to write an XML file to the website's root folder dynamically and therefore need to know the folder's physical location.
URL....This link shows a demo that let user to put origin and destination then get direction. I want to know how to add a option which is let user to use their current location as origin location (Location from).
I have a static class with serveral static methods. In these methods, I'm trying to access the current thread's context using HttpContext.Current. For example:
var userName = HttpContext.Current.User.Identity.Name;
However, when I do that, I receive a NullReferenceException, the infamous "Object reference not set to an instance of an object."
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).
As per title. I want to be able to save some data in a cache object but this object must be available to all users/sessions and can expire.What is the best method to achieve this in a asp.net web app?
I have some code that works fine when I need to delete some image files from a directory on my web server:
Dim ImageURL As String = dsImages.Tables(0).Rows(iImgRow).Item("ImageURL") Dim physicalName = Server.MapPath(ImageURL) oUpload.DeleteFileFromServer(physicalName, iAdid, iImgID)
.but I am running into a problem when a maintenance task running in a separate thread at set intervals determines that files like the above need to be deleted:
Dim ImageURL As String = dsImage.Tables(0).Rows(i - 1).Item("ImageURL") Dim iImgID As Integer = dsImage.Tables(0).Rows(i - 1).Item("ImageId") Dim physicalName As String = HttpContext.Current.Server.MapPath(ImageURL) oUpload.DeleteFileFromServer(physicalName, iAdID, iImgID)
In this latter case, HttpContext.Current.Server.MapPath(ImageURL) has a value of Nothing.Is there a way to get the full path for this case?
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?
am writing a web service in vb.net/asp.net 2, that needs user's name. It works fine when the url request is "www.mysite.com" but if any one has logged-in using "mysite.com" without a "www" and goes to the page that calls my web service, The HttpContext.Current.User.Identity.Name gives null. How can I resolve this problem?
Last night I wrote up my first IHttpModule to do some request processing. I'm using a regular expression to inspect the raw url. The IHttpModule will be called on every request, so it seems reasonable to do some sort of caching of the regular expression object to prevent creation of it on every request.
Now my question... what is better: use the HttpContext.Current.Cache to store the instantiated object or to use a private static Regex in my module?I'm looking forward to the reasons why. Just to clarify: the regex will never change and thus always be the same thing.
I am searching to find a way to read and write on session data but with out having the HttpContext.Current.Why I won to do that ?, because I wish to make some action with the user Session after the page have been close and unloaded. For example, a user load and see a page, then I create a thread to make some action and let user go. Inside this thread I like to read the session data, but in this case HttpContext.Current is not exist any more.
So is there a way to read Session Data knowing just the session id.I store my session inside an sql server, and I see them... its there on table ASPStateTempSessions . How can I read them "offline" and manipulate them ?
