C# - MVC: Filtering/Varying By Http Status Code In OutputCache Attribute
Jul 1, 2010
In the ASP.NET MVC site that I'm writing, I'm building a generic Error Action that is routed to by an HttpModule, following this tutorial. In this Action, I will return a View corresponding to the status code that is applied to the response inside the HttpModule (after doing this, the module transfers the request over to the Action in question).
That's all good, except that I want to implement caching. I don't want to use the OutputCache attribute without filtering/varying, because that would mean that the page would be cached once. I want the page to be cached once for every possible status code.
Is it possible to somehow filter/vary with OutputCacheAttribute's properties, so that each Response.StatusCode is cached separately?

I'm building an ASP.NET MVC 2 site where I'm using the OutputCache parameter heavily. However, I have a concern: using such caching may interfere with authentication.On all of my pages, I display whether the user is logged in or not. Furthermore, in some of my Views, I do filtering based on user role to determine whether or not to display some page content (for example, the Edit link on one of my pages is only shown to users in the roles of Moderator or Administrator)

I successfully implemented role based authorization in ASP.NET. When a person does not have the needed role he gets to see an error page for 401.2 not authorized.
What I would like to accomplish now is to have a custom 401 page in my application and have it redirected there via settings in the web.config. I tried this:
<customErrors mode="RemoteOnly" defaultRedirect="GenericErrorPage.htm">
<error statusCode="401" redirect="NoAccess.htm" />
</customErrors>
But this does not get caught. Do I have to override it in IIS instead? I hope not as that would make getting things deployed harder.

In ASP.NET you can set the Response.StatusCode to for example 404. Should the status line / description always be set? (to in this case "404 Page Not Found")
How do you get the description if you only have the code (404)? Is this somewhere in the framework or do you manually have to hardcode the descriptions?

I'm writing an HTTP handler in ASP.NET 4.0 and IIS7 and I need to generate a file-not-found condition.
I copied the following code from Mathew McDonald's new book, Pro ASP.Net 4 in C# 2010. (The response variable is an instance of the current HttpResponse.)
response.Status = "File not found";
response.StatusCode = 404;
However, I found that the first line generates the run-time error HTTP status string is not valid.
If, instead of the lines above, I use the following:
response.Status = "404 Not found";
Then everything seems to work fine. In fact, I even see that response.StatusCode is set to 404 automatically.
My problem is that I don't want this to fail on the production server. So I'd feel much better if I could understand the "correct" way to accomplish this. Why did the first approach work for Mathew McDonald but not for me? And is the second approach always going to be reliable?

I have a tricky requirement where I need to categorise documents attached to a product, available for download, based on the status of the user viewing the product. I.e. my site displays a list of products, clicking on one displays a product details page, and this page includes a list a documents related to the product, such as data sheets, user manuals, etc.
I have been asked to group documents into three classes of availability, v.i.z. those available freely to all users, including anonymous; those available to logged on users; and those available to anonymous users that provide contact information before downloading the document, presumably to boost sales leads.
The anonymous and logged on availabilities are quite easy, but the third seems a bit tricky to me. My first question is, is there a way I can filter documents for only logged on users without hooking into ItemDataBound or something, and my second question is, what is recommended for the case where a user must supply contact information to download a document?
In the second question, it has crossed my mind to actually register the user, but without them having to visit the new user registration page, and then I have role based filtering of documents. Currently the new user registration process automatically adds the Member role to all new users. Users I register 'quietly', just so they can download a document, wont be assigned the Member role, distinguishing them from normally logged on members.

I wrote an ASP.NET page that requires HTTP Basic authorization, which I put in the Page_Load function:
void Page_Load(object sender, EventArgs e)
{
string auth = Request.Headers["Authorization"];
if (string.IsNullOrEmpty(auth))
{
Response.StatusCode = 401;
}
else
{
string[] usernameAndPassword = Encoding.UTF8.GetString(Convert.FromBase64String(auth)).Split(':');
string username = usernameAndPassword[0];
string password = usernameAndPassword[1];
Login(username, password);
}
}
When I try to view the page in a browser (either Firefox or IE), it asks me for the username and password, and then...asks me for the username and password again.
Why does this happen, and how can I fix it?

The app_offline.htm file that ASP.NET serves returns the http status 503. This is the correct behavior for most situations. However, in the scenario where a specific URL is requested (e.g. [URL]), I'd like to change the returned http status to 200, while still returning http status 503 in all other situations. Is this possible?
The reason why I want to do this is whenever we do scheduled maintenance on our website, we use the app_offline.htm file, but we don't want our uptime monitoring service [URL] to report downtime during our scheduled maintenance.
I assume this would have to be at the IIS level because the app_offline.htm gets served very early on in the request processing cycle.

In my asp.net web site I have custom error pages defined as following in my web.config file.
<customErrors mode="On" defaultRedirect="~/defaulterror.htm" >
<error statusCode="404" redirect="~/404.htm" />
When file is not found it correctly display 404.htm page but the issue is when I do Fiddler trace it returns 302 as HTTP status code.This is a big issue for search engine page indexing due to this lot of broken links still have been indexed recently because of this in my web site. how can I prevent returning 302 as HTTP status code for file not found errors and return 404 for file not found errors.I am using asp.net 3.5.

I am trying to call webservice from my web application. The web application had integrated windows authentication. I've written custome principal class to do authorization. But when I give call to my web service with default credentials it gives me 'the request failed with http status 401 unauthorized.' error.
When I give call to my local webservice it is running fine (It also has integrated windows authentication) But when I add reference of same web service from QA server I am getting this error. Not sure what is happening. I also tried
WS.PreAuthenticate = false;
WS.Credentials = System.Net.CredentialCache.DefaultCredentials;

I have a asp.net c# web application with contains reports in remote processing mode. I am using the report-viewer control to render the reports. When I run the application in debug mode, I'm able to view my reports however when I publish the application to a different server I get this error message:The request failed with HTTP status 401: Unauthorized.
My report server is on a different server than the location of my published web application. I have added new role assignment to my report server and also added to my web.config but the error persists. I think I am missing something in my aspx page for reportviewer.

I am connecting to remote server for web service using ASP.NET 3.5 web site. something like, [URL]. Remote server is providing digest authentication to access the web service. I dont have access to modify authentication on the remote server but I have an windows account on that server. If I try to Access service WSDL through programming I get the following error:
The request failed with HTTP status 401: Unauthorized. Same web service if I try to access through browser, [URL], it asks for user name and password. Entered windows account user name and password, still getting error: You are not authorized to view this page, HTTP Error 401.1 - Unauthorized. How to pass the digest authentication credentials to the web service through visual studio or any other programmatic method?

I created aMicrosoft.Reporting.WinForms.ReportViewer with a window application. It worked fine when I was in net A with domain A. My application is now moved to net B with domain B. However when I login to my computer I still login netA with domain A, userID and password for A. I then use a A/B switch to switch to net B to run my application running ReportViewer (no login directly to B). But when I run ReportViewer I got errors like below.
