MVC :: HttpContext.Current.Request.Url.Host Not Correct When Using Host Headers In IIS 7.5
Feb 24, 2011
I have one IIS entry with AppPool integrated mode. There are 5 or more host headers assigned. The application pulls data based on the host name from Request.Url.Host. When I have 2 or more sites open at the same time the value of the Request.Url.Host is the same across all the sites. About every 30 seconds it resets itself to the correct value from the last request and shows that value on the other sites. So ultimately the sites are loading the same data. The value in the HOST server variable is incorrect as well.
Why does HttpContext.Current.Request.Url.Host return a different URL than the URL used in the Web browser? For example, when entering "www.someurl.com" in the browser, the HttpContext.Current.Request.Url.Host variable is equal to "www.someotherurl.com".
I've got an ASP .Net application running on IIS7. I'm using the current url that the site is running under to set some static properties on a class in my application. To do this, I'm getting the domain name using this (insde the class's static constructor):
var host = HttpContext.Current.Request.Url.Host;
And it works fine on my dev machine (windows XP / Cassini). However, when I deploy to IIS7, I get an exception: "Request is not available in this context".
I'm guessing this is because I'm using this code in the static constructor of an object, which is getting executed in IIS before any requests come in; and Cassini doesn't trigger the static constructor until a request happens. Now, I didn't originally like the idea of pulling the domain name from the Request for this very reason, but it was the only place I found it =)
So, does anyone know of another place that I can get the host domain name? I'm assuming that ASP .Net has got to be aware of it at some level independent of HttpRequests, I just don't know how to access it.
I am a bit new to asp.net and I have been trying to host a asp.net site on my local machine (Win2k3) with a host header.
I initally created the web site with default (none) host headers on the port 800 .
Later on I edited the default header from the web site properties tab and gave a header something like this - test.site.com
I made the entry in the host file for this header.
I try accessing the site by hitting http://test.site.com but i dont see my web page, instead i see some internet url.
I know that the host header has been setup well because i can ping it successfully from the cmd. Also, i have made changes in the browser to by- pass the proxy server.
I have problem of accessing my website created using visual studio on my local pc. the pc using windows 7 with static ip address has been configured and i have added a hostname "192.168.0.1 hosts myweb.mylocal.com" on c:windowssystem32driveretc. on the IIS i have configured the binding myweb.mylocal.com with impersonation set enabled and windows authentication is enabled.
the user login just keep prompting eventhough i have entered the correct username and password.
My kind webhost (1and1) royally asked me to go elsewhere to do something like this.
I have 2 sites. One of them was developed by a .Net programmer. Now I am contracted to implement a PHP site and fetch data from the .Net site.
There is an ASP.Net form that a customer fills and when they hit submit, the data gets stored in SQL Server DB. How do I also store the same data in MySQL parallelly? I cannot directly use some database connectors with ASP.Net since MySQL connectivity is not supported on 1and1 Windows hosting (biz account, no less!).
What I thought of is to publish an RSS feed of entries in ASP.Net site and routinely scrape that data into MySQL on Linux host. It is an overkill, I know. Not efficient.
I created web pages that used an SQL database on my home computer. That DB allowed me to use data types such as 'date' and 'time'. But when I transferred my website to a host server, I discovered that its DB does not accept these types. They only use 'datetime' and 'timestamp'. I changed the tables in the DB on my computer to conform to the same format as on the host computer. I also changed the properties to the new data types with the O/R Developer and re-published the website files to the host server. But I keep getting the same error message that states the server does not support 'date' data types whenever I execute a web page that uses that table column. The C# code states "officetable.StartDate = DateTime.Today;"
I am just wondering whether it is possible to return the name of the view an ascx control is currently being rendered in? Is there an object I can use to access the name?
Basically I want the control to dynamically set certain text within itself dependant on the view it is rendered within.
I am working on an update to one of our sites. This version will have unique behaviors based on the host name in the request. In order to test this behavior, I modified my computers host file by adding entries that point back to my computer.
Everything seemed to be working fine, until I started working with the Session object. I discovered that after each request all my session variables were lost. Further investigation revealed that each response from the server contained a new SessionID.Why is that?I was able to hard code some flags to complete my testing using 'localhost' for requests without any problems.
I have IIS on S2k8 and a website with Windows Authentication only.
I can easily reproduce the following scenario, where HttpContext.Current.Request.LogonUserIdentity.Name has a bad value:
Login to website using FireFox, using an Active Directory account "user" (I could use IE to reproduce the same, but it's a few extra steps)Display <%=System.Web.HttpContext.Current.Request.LogonUserIdentity.Name%> on the pageIt shows "DOMAINuser", which is correctI go into Active Directory and rename the account to be "userX" instead of "user" (both SAMAccountName & UPN)Restart FireFoxLogin to website using "userX" accountThe page still shows "DOMAINuser", instead of the expected "DOMAINuserX"
It seems almost as if IIS has cached the old username and it's not showing me the new one, even though I explicitly enter it in the login prompt.
In an asynchronous process, I need to get the name of the domain/server the web application is running on. But in that situation HttpContext.Current is not available, so I cant use HttpContext.Current.Request.ServerVariables("SERVER_NAME").
I have various web pages that need to build up a URL to display or place it in an emitted email message. The code I inherited had this value for the name of the webserver in a Public Const in a Public Class called FixedConstants. For example:
Public Const cdServerName As String = "WEBSERVERNAME"
Trying to improve on this, I wrote this:
Public Class UIFunction Public Shared myhttpcontext As HttpContext Public Shared Function cdWebServer() As String Dim s As New StringBuilder("http://") Dim h As String h = String.Empty Try h = Current.Request.ServerVariables("REMOTE_HOST").ToString() Catch ex As Exception Dim m As String m = ex.Message.ToString() 'Ignore this should-not-occur thingy End Try If h = String.Empty Then h = "SomeWebServer" End If s.Append(h) s.Append("/") Return s.ToString() End Function
I've tried different things while debugging such as HttpContext.Current.Request.UserHostName and I always get an empty string which pumps out my default string "SomeWebServer". I know Request.UserHostName or Request.ServerVariables("REMOTE_HOST") works when invoked from a page but why does this return empty when invoked from a called method of a class file (i.e. UIFunction.vb)?
When user requests http://localhost/WebApp1/Default.aspx, txtApplicationPath.Text should be assigned "/WebApp1", while txtAbsolutePath.Text should be assigned "http://localhost/WebApp1/Default.aspx", but instead both textboxes display empty strings.
I was/am struggling with security for my first MVC applicaiton. It worked out great for me, but not for my users. I wanted to use Windows Authentication (and I seem to have that working). But when I was still trying to implement it, I was on one of our users computers where they were logged in. I navigated to the main Index page and used the supplied MVC login link and *MY* credentials. So now every time that user navigates to that page, it logs her in as me. We are using IE8, I have deleted all the cookies, passwords, forms information I can fine through Tools|Internet Options|Tool|Content|AutoComplete.
I have an application that I use to run Exchange Powershell commands inside C# code like below. This is an example of the relevant lines I use to run the powershell command.
This code works perfect in all cases until now. the script I am trying to run instead of the one above is to set the RetentionPolicy for a mailbox. The script I am trying to run looks like this: Set-Mailbox -Identity 'rj' -RetentionPolicy 'Main Campus Retention Policy' When I run this in powershell itself it works perfectly but when I try to run it using the code below I get the error, "Cannot invoke this function because the current host does not implement it."
From this error, it almost seems like the command that runs in C# cannot run the RetentionPolicy command but that doesn't make much sense. I have Googled this and tried everything suggested but no luck.
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.
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.
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).
I'm want to run a "background job" in my ASP.NET application (periodically, as separate thread). And I need host name (DNS name or IP) to do my tasks. The problem - HttpContext.Current may be not available here (it's NULL).
Is there any way to get a host name in not using HttpContext.Current.Request.Url.Host.
I have a website has already hosted on EasyCgi (suppose that it's called website1). I have to host another one (website2). So I created a folder called "website2" under the website1 root folder. then I FTP all the content of website2 to the "website2" folder.After that, I tried to request the URL: and nothing happen...Just an error page display that contains:
