Can't Set HTTP Vary Header In IIS7 Classic Mode
Jan 16, 2010
First, a little background. I have written a custom HTTP compression module for ASP.NET. My development machine has Windows 7 Ultimate, which comes with IIS7. My production environment uses IIS6.
The problem I'm having is, Resource Expert Droid (redbot.org) tells me that I need to add a header to my response to properly support compression: "Vary: Accept-Encoding"
On IIS7 in integrated mode, it works properly. However, in classic mode, which is how my application ultimately runs, I cannot get my code to output this header using any of Response.AppendHeader(), Response.Cache.SetVaryByCustom(), or Response.Cache.VaryByHeaders.

we are running a complex 64-bit ASP.NET 2.0 application on W2008 R2 Standard and stress tests done with VS2008 Team System have indicated that integrated pipeline mode is 30% slower than classic mode.
We have compared the application traces extensively and it appears that integrated mode is uniformly slower than classic. That is, there is no single point that causes delays in integrated mode.
This is quite the opposite to everything Microsoft says about the integrated pipeline, so it might be that there is something quite wrong with the configuration of the integrated mode or the server. But we have not found any settings that would have any effect on this. Some complaints that Sharepoint and reporting services are slower in integrated mode can be found, but our application does not use them so this is quite likely unrelated.

I have a need to run an application in classic mode for backwards compatibility with a specific application, and am trying to understand what kind of impact that will have on the performance of an MVC application that is running on the site. If we put a few static file maps (for .js, .css, .png, etc) above the ASP.NET wildcard map to reduce the amount of processing by the ASP.NET handler, will we be approaching the integrated mode in terms of performance?
The thing i'm primarily concerned with is any effect this might have on output caching. I understand that integrated mode might (?) allow for the output cache to handle non ASP.NET content, but that isn't really a concern. We're more interested in ensuring that the MVC application has full use of the output cache. Empirically i've found that the two configurations operate on par when things go well, but if the page references resources that are not available, the integrated mode tends to fail much more quickly than the classic mode (e.g. 500 ms vs 10 seconds), reducing 'hang time' on the page load.

Is it at all possible to use IIS7's rewrite capability in web.config to strip a particular HTTP header from a client request?We have an application that makes an HTTP POST to our website, and apparently the request contains the HTTP Expect header. Previously this was not a problem, but we've switched hosts and now the site is returning HTTP error 417 Expectation failed. So the real solution is to fix the software so it doesn't send the Expect header, but that can't happen soon enough for the folks in charge, who'd like to come up with an immediate web-based fix.I've used ISAPI_Rewrite before and I've read that it can strip a header, and the new host claimed they had ISAPI installed... but that seems to have been a lie, as I cannot get it to work, and support's only response on the subject is "use IIS7 Rewrite instead."

I am attempting to set the content-type of an asp.net .ashx file to text/plain.
When I run this through the ASP.NET Development Server, the content-type is properly set. When I serve it through IIS7, however, the content-type (and any other header values I set) don't come through (it came through as text/html).
The only value set in the HTTP Response Headers section of IIS Manager is the X-Powered-By attribute. I tried setting the content-type here, but that didn't work. But if I removed the X-Powered-By attribute, it was removed from the header.

I'm trying the above - Visual Web Developer 2008 express edition with SQL Server 2005 express using VB code behind on ASP.net 3.5 framework. I need to incorporate and amend some externally supplied classic asp pages, so switched to local IIS7 for compilation/run. I can run these pages, but am unable to amend them and have the changes reflected in what I see. Is this possible with this setup? Is there a configuration setup that I may need? Has anyone successfully done the above before?

I took a copy of a website that works fine on a server (done have server access) but when I set up a website in IIS7 and run the classic asp code loading a page is taking nearly a minute. It always loads the pages but just takes forever.

Does anybody knows if it is possible to make URL routing in a ASP.Net webforms website that is running under the Classic .NET AppPool.
I've tried a few things here, but it just works when I switch from Classic AppPool to Default AppPool.
** the web site MUST run under Classic AppPool.

I'm having a tough time implementing mixed-mode authentication (windows & forms based) for my application using IIS 7. Doing it in IIS6 is easy, but the process doesn't translate to 7/7.5 - and my research has led to me to conflicting answers, none of which.
I have redirect page called WindowsLogin.aspx, and a forms-based one called Login.aspx. I'm having difficulty enabling Windows authentication for just WindowsLogin.aspx.

I am trying to implement single sign on for users within our domain and if the are not then they get re-directed to the login screen to use forms authentication.
I have followed this tutorial below
however I get two issues firstly if I go to my forms authentication page no css or images now display and if i try to login i get an error.
If I go to the login page which should recognise me from the AD I get 401 - Unauthorized: Access is denied due to invalid credentials. You do not have permission to view this directory or page using the credentials that you supplied.

For an ASP.NET 4.0 / IIS7 web app, I would like to support compressed HTTP requests. Basically, I would like to support clients that would add Content-Encoding: gzip in the request headers, and compress the body accordingly.
Does anyone known how I achieve such a behavior?

I have published my site using Visual Stuido's 2008 publish feature. I have then copied these files to a windows 2008 web server with IIS7 installed, it also has .net 3.5 sp1 and MVC installed In IIS I added the site using the 'Add a new site' right click option and then pointed this at the directory my site files are located in, I used the default application pool and it is set to integrated. Then when I attempt to browse I got the error message The Web server is configured to not list the contents of this directory. So I added Default.aspx to the default document list and I then get the following error message
HTTP Error 404.3 - Not Found The page you are requesting cannot be served because of the extension configuration. If the page is a script, add a handler. If the file should be downloaded, add a MIME map. Has anyone got any ideas on what I do next ? I have read lots of articles on this online but most are confusing and dont explain the solution in simple terms Surely it should be pretty straightforard to just deploy an MVC website to IIS7

I have a site that dynamically loads website contents based on domain host name, served from IIS7. All of the domains share a cached collection of settings. The settings are being flushed from the cache on almost every page request, it seems. This is verified by logging the times at which the Cache value is null and reloaded from SQL. This codes works as expected on other servers and sites. Is it possible that ASP.NET Cache is being stored separately for each domain host name?

I just switched from Classic Mode to Integrated Mode and now HttpContext doesn't seem to exist in my ASP.NET application. I can't even add a Watch to HttpContext nor to HttpContext.Current.
I'm using FluorineFX where in the Web.config a HttpModule is defined. Apparently, in IIS7 Integrated Mode, these HttpModules need to be added to the Modules section in System.WebServer. I have done this, but now I'm having this HttpContext problem...
Code is in a simple service class being called by Flex (amf).
if (HttpContext.Current.User.Identity != null)
{
...
Web.Config (I don't know how to display this properly in Stack...):
<?xml version="1.0" encoding="utf-8" ?>

I know how to switch to "Classic Mode" (from "Integrated Mode") in the full IIS via application pool settings. But I can't find how to do it in the current IIS Developer Express beta.
The MS Developer Express FAQ says it can be done, but not how. It's not in the WebMatrix GUI, as far as I can tell. Maybe customization of the Developer Express project file, but I don't see any documentation for that at all.
FYI, there is a Settings area where you can set SSL, CLR version (2.0 in this case), which is where I figure the Pipeline mode (Classic/Integrated) would be, but it's not there.

I have web services built with ASP.NET and ASP.NET clients consuming them. When consuming the webservices, how would I to force the clients to use https?
I don't want to force the whole site to use https by turning on require SSL in IIS.
Can I use the IIS7 URL rewrite module to re-route http requests to https?

In IIS6 the scenario below is working perfectly.I have an HttpModule called URLRedirect which examines URLS and by using RegEx rewrites of applicable. An example is a URL "/doc47.pdf" gets redirected to docpdf.ashx?id=47 Then the docpdf.ashx used the id value and, using a database builds an application/pdf document and returns it. Since I need to validate that the user has access to the data, the first line of the ProcessRequest(HttpContext context) function is:if (context.User.Identity.IsAuthenticated) ..... This is where the problem occurs, but more details first.
On a webpage, access to which is restricted to lgged on users who meet certain criteria there is a link which allows the user to present the page as a PDF document. This is achieved by using javascript to open a popup window using the window.open("/doc47.pdf", ... ) function.This all works fine under IIS6 and under IIS7 if I change the mode to Classic. But, under IIS7 in integrated mode, the following happens.The line in doc.ashx described above raises an exception because context.User == null. But, and this is interesting, if instead of using the link that opens the popup window I instead type /doc.pdf?id=47 into the address bar, the PDF document displays correctly.So this indicates to me that the URLRedirect Module is somehow losing the logged on user information.

I have a simple web site with two pages. One displays a list of files, and the other streams a file when it's clicked in the list. All was fine in production for 6 months, but now I have to move the site to Windows 2008/IIS7. I have it mostly working, but the files don't open properly (in Firefox) because my content-type header is being ignored. On the production site (IIS6) the headers are (using Fiddler):
HTTP/1.1 200 OK
Date: Tue, 09 Feb 2010 16:00:51 GMT
Server: Microsoft-IIS/6.0
X-Powered-By: ASP.NET
X-AspNet-Version: 2.0.50727
Content-Disposition: attachment; filename="myfile__foo.pdf"
Content-Length: 236841
Cache-Control: no-cache, no-store
Pragma: no-cache
Expires: -1
Content-Type: application/octet-stream
but on the test IIS7 server I get:
HTTP/1.1 200 OK
Cache-Control: private
Content-Length: 236841
Content-Type: text/html; charset=utf-8
Server: Microsoft-IIS/7.5
X-AspNet-Version: 2.0.50727
Content-Disposition: attachment; filename="myfile__foo.pdf"
Fiddler also reports a protocol violation and says "Content-length mismatch: Response Header claimed 236841 bytes, but server sent 238378 bytes."
My code looks like this:

I have the following setting in my web.config to redirect to a default page:
<defaultDocument>
<files>
<clear/>
<add value="default.aspx"/>
</files>
</defaultDocument>
For example when a user enters www.homeforhire.com they should be redirected to default.aspx (for operational reasons the user is then redirected to
www.homeforhire.com/home.aspx).
Instead an error is caught in the Rewrite module (which should not be activated). I am using an http module to perform URL rewriting.
It appears as if the default document setup is not working correctly, and the requested page ~/ is being sent to the Rewrite module, causing an error (which is then caught by my error handler and the user is redirected to the home page).
Entering www.homeforhire.com/default.aspx works correctly.
Can anyone tell me why the default document settings in the web.config do not appear to be working?

We are implementing a single sign on mechanism in an enterprise environment, where the token is shared between applications using HTTP header. Now, in order to do the integration test, I need to write an application to simulate this. Is there any way in ASP.NET where I can redirect to another web-page and pass a custom HTTP header in the process?
