HttpContext.Current.Response.Redirect With Visual Studion 2010?
Mar 23, 2011
As I have migrated Web Application from 3.5 (VS 2008 ) to 4.0 Vs (2010)
Now i am having problem with Response.Redirect
As I in .aspx pages i have found the following solution and it is working fine.
old Code with is not Working in Vs2010
[code]....
But now I need to Redirect from the class librarySo can any one guide me on the same.. i can i redirect .. AS I have try with HttpContext.Current.Response.Redirect(strURL); but it is not working.
In ASP.NET, if a file was downloaded on a page that was protected by SSL, through a server-side postback that writes to HttpContext.Current.Response.OutputStream, is the transmission that file ALSO protected by SSL?
What is the easy/safe way to get all HttpContext.Current data (like querystring, etc) in the previous page, after response.redirect or server.transfer to another page?
I have a logon/register control that is on several pages. Users are logged on with code: - FormsAuthentication.SetAuthCookie(Userid, False) Response.Redirect(Request.Url.AbsoluteUri) ' Round trip is necessary to complete logon
All this was working OK, except that there was a problem with Internet Explorer users: if their browser had the default privacy setting the authorization cookie was rejected. There was no message, but they were not logged on. See [URL] To try to solve this problem I changed to cookieless authentication, but now the logon control doesn't work. The problem is that after cookieless authentication the URL changes from
[URL]
However Request.Url.AbsoluteUri remains http://localhost:3641/TestGDB/login_pages/home2.aspx even after the logon, and so with cookieless authentication the user is not logged on as there is no authentication ticket in the redirect URL.
The problem is "solved" by changing the Redirect statement to Response.Redirect("~/login_pages/home2.aspx") which works perfectly for this particular page, but is obviously wrong when the control is on other pages.
I have a page that is used to add info from a gridview into a user's profile. I have explained my issues after all of the code. Here is the applicable code(s) involved:
Protected Sub AddToCart(ByVal sender As Object, ByVal e As CommandEventArgs) For Each gvr In GridViewItems.Rows Dim txtGiftAmt As TextBox = (CType(gvr.FindControl("txtGiftAmt"), TextBox)) If txtGiftAmt.Visible = True Then Dim customPrice As String = txtGiftAmt.Text.ToString 'HERE is where I would like to set the new price variable value somehow End If Next Dim scart As New ShoppingCart scart.AddCartItem(e.CommandArgument.ToString()) Response.Redirect("~/ShoppingCart.aspx") End Sub
This sub is called by the following button when clicked:
[Code]....
Here is the sub from the ShoppongCart Class named AddCartItem:
[Code]....
Here is the problem that I am having: I have one specific item that allows user's to define their own price (for this item only). By putting this price in a session variable seems to be the easiest way to handle this (at least for me), but the session variable's value always "lags behind". By this I mean that the first time the items is entered, it uses the default value of cartItem.ItemPrice. The second time the same item is added (with the intention of a different price), this new item's cartItem.ItemPrice is set as the first session("customPrice").
Because the user is selecting his/her own price for this item, I am not worried about lack of security involved with using query string to pass this price, but I can't get the string passed to the ShoppingCart class correctly (shows up null). Is there a way to append this customPrice to the current page's query string before the Response.Redirect takes place? If I understand this correctly, the Response portion "posts back" to the current page before the Redirect sends us on our merry way, right?
I'm using 2010 to build a website application targets .net framework 4.
I use Response.Redirect(url) to transfer user to another page. All these redirect work fine when I debug. After I publish the website project to the sever. I visit that website on the server. All the redirects work fine but in one page.
In that page. I have a button control. when user click the button, he/she will be transferred to another page. So in the button_onclick event, I have:
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 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.
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).
I 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:
I want to redirect to "~/City/Göteborg", but if I just write Response.Redirect("~/City/Göteborg"); I will end up with an ugly URL in the address-bar like this: http://www.mysite.com/City/G%c3%b6teborg..
So my question is how to redirect to obtain a clean url like http://www.mysite.com/City/Göteborg?
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?
