Check If Our Code Is Executing In Integrated Pipeline Mode Or Not?

May 3, 2010

Is it possible to check if our code is executing in Integrated Pipeline Mode or not?

There are some ASP.NET class properties that only work in Integrated Pipeline Mode, and I want to avoid raising an exception if there is a way to test if our code is executing in that environment or not.

IIS7 Integrated Pipeline Mode Slower Than Classic?

Sep 20, 2010

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.

HttpHandlers / Modules :: Trying To Write An HttpModule That Will Work In IIS7 With Integrated Pipeline Mode AppPool?

Jan 2, 2011

am trying to write an HttpModule that will work in IIS7 with integrated pipeline mode AppPool. Within this module I need to access Session variables and to be able to capture the Session Start and End events. I have found a couple of articles on this topic that indicate the need to modify the behavior of the HttpHandler in PostAcquireRequestState to force the Session for the context to be initialized. The article I am using as a template is posted here:[URL]In my case I am getting the following error:

[NullReferenceException: Object reference not set to an instance of an object.] System.Web.PipelineModuleStepContainer.GetEventCount(RequestNotification notification, Boolean isPostEvent) +30 System.Web.PipelineStepManager.ResumeSteps(Exception error) +1112
System.Web.HttpApplication.BeginProcessRequestNotification(HttpContext context, AsyncCallback cb) +113 System.Web.HttpRuntime.ProcessRequestNotificationPrivate(IIS7WorkerRequest wr, HttpContext context) +616

I believe that this error implies a problem with attempting to attach an event handler multiple times. I am aware that the modules Init function can be called more than once and have set a static initialization flag which ensures that I will only ever attach the event handler once.In the most condensed form my code is as follows:

public class HttpModule : IHttpModule, IRequiresSessionState

IIS Configuration :: HTTP Error 500.23 Setting Detected That Does Not Apply In Integrated Managed Pipeline Mode

May 7, 2015

I am trying to export crystal report to pdf inĀ, though the code is working well on localhost but on server I get error

HTTP Error 500.23 - Internal Server ErrorAn ASP.Net setting detected that does not apply in Integrated managed pipeline mode.

The crystal report is showing abnormal behaviors.I am using a CrystalReportViewer on which i have set the CrystalReportSource1 using the viewer Tasks.

The code on page load is :-

DataSet ds = new DataSet();
string sql = "select * from Test";
OleDbDataAdapter da = new OleDbDataAdapter(sql, cn);


During the troubleshooting i encountered another unusual issue, where i tried a new crystal report with just simple report. That simple crystal report is not showing data & the toolbar images are not rendered. I googled on this but didn't found conclusive thing.

Visual Studio :: Debugging Global.asax Code In Integrated Mode?

Feb 21, 2011

migrating my ASP.NET project from IIS 6 to IIS 7.5 I came across an issue with the Managed Pipeline Mode set to 'Integrated'.I have a Global.asax file in my web root to initialize some objects, gather data etc., however I am not able to hit breakpoints in the associated code-behind file (VS 2008). The code is executing very well (as I can tell from Eventlog), but I want to step into all that initializing there and need to have the debugger attached properly.Everything is working as expected in Classic pipeline mode. Since I'd like to benefit from Integrated Mode features in the future I wonder if I have to give up the ability to debug my Application start and error events...

Get Custom Error Pages Working For Classic ASP With IIS 7 Integrated Pipeline?

Oct 6, 2010

I'm working on a website with legacy Classic ASP pages (being converted to ASP.NET on an as needed basis) and new ASP.NET pages. Use of IIS 7 Integrated Pipeline has been very helpful with our configuration. For example, we were able to get forms authentication working auto-magically with the classic ASP pages simply by configuring the appropriate sections of the web.config file (i.e. no changes were required to the Classic ASP pages, for more info see this).

A colleague of mine believes that custom error pages, as specified in the web.config <customErrors> section, should also be auto-magically applied to the classic ASP pages, but for our website it only works for the ASP.NET pages. Nor have I been able to find any information describing the capability of applying custom error pages to Classic ASP with the IIS 7 integrated pipeline. Is it possible to apply custom error pages to Classic ASP pages per a web.config for an website running under IIS7 with integrated pipeline? If so, how?

.net - IIS7 Integrated Pipeline: Interaction Between MaxConcurrentRequestsPerCPU And RequestsQueueLimit Settings?

Jan 19, 2011

Firstly there's a great overview of the IIS7 HTTP request lifecycle and various settings that affect performance here:

ASP.NET Thread Usage on IIS 7.0 and 6.0

Very specifically though, in dotNet 4 the defaults for maxConcurrentRequestsPerCPU and requestsQueueLimit are set to 5000. E.g. equivalent to: (in aspnet.config):[code]....

Seems to me that on a multi-CPU/core server the requestQueueLimit here will always be invoked well berfore the 'perCPU' limit. Thus, if a max of 5000 requests per CPU is what you actually want then I would expect that the requestQueueLimit needs to be increased to 5000 * CPUCount or just disabled altogether.

Is my interpretation correct? If so can I disable requestQueueLimit? (set it to zero?). The documentation on this setting doesn't appear to address this question (so maybe I'm missing something or misreading?)

** side note from the above article: The requestQueueLimit is poorly named. It actually limits the maximum number of requests that can be serviced by ASP.NET concurrently. This includes both requests that are queued and requests that are executing. If the "Requests Current" performance counter exceeds requestQueueLimit, new incoming requests will be rejected with a 503 status code)

Change The .NET Version On The Control Panel From Ver. 2.0 To Ver. "2.0 Integrated Pipeline" All The Ajax Controls Disappear From The Page

Apr 23, 2010

Development environment: VS2008, Win XP

Iam working on a web form that incorporate ListView control with Ajax RoundCornerExtender.On my machine everything works fine, and looks okay. After uploading the page to the host server the ListView Item DIV with the round corners looks broken, I contacted the host server support and they asked me to check for version issues, I reinstalled the Ajax Control Toolkit as well as the .Net Framework 3.5 but still no change. When I change the ASP.NET version on the control panel from ver. 2.0 to ver. "2.0 Integrated pipeline" (they say its ver. 3.5) all the Ajax controls disapear from the page.

One more thing I noticed, when the ASP.NET ver. on control panel is set to "2.0 Integrated pipeline" (3.5) and I execute the following -


I get ver. 2.0.50727.4200 which is ASP.NET 2.0, why things looks okay on my machine and look different on host server ?

Get The Exact Raw URL In IIS 7.0 Integrated Mode .NET 4.0

Nov 1, 2010

After some changes in web.config now IIS allows characters like ":" in URL but it makes some modifications. For example:

http://localhost/a///b => http://localhost/a/b (remove all slashes but one)
http://localhost/a => http://localhost/a/b (changes backslash with slash)
I want URL string from within a HttpHandler (I use Request.RawUrl) as it is without any change.

May 19, 2010

Our code relies on checking the Context.User.Identity value in the Global.asax Application AuthenticateRequest(...) method to retrieve some information about the logged in user. This works fine in classic mode but when I flip IIS to use the Integrated Pipeline "Context.User" comes back as null, but only intermittently.I have < authentication mode="Windows"> and only Windows Auth enabled in the Virtual Directory.

C# - How To Programatically Detect If Application Is Running In IIS 7.0 Integrated Mode From Within .NET Page

Generally we should have control of our AppPools and be able to force the Managed Pipeline Mode. In my case I don't have control and would like to implement the code behind code a little differently based on the Managed Pipeline Mode (Integrated vs Classic). I just don't know how to detect this. Is there a simple way to do it from within the code behind page?

SQL Reporting :: ReportViewer Control Version 8.0 Compatible With Integrated Mode Of IIS 7?

Dec 7, 2010

Ultimately, we need to know if version 8.0 of the .net Sql ReportViewer control is compatible with IIS7 running in Integrated Pipeline Mode.Regardless of the countless forum posts and articles we've read and suggestions we've tried, we've been unable to get this combination to work.

We're in the process of upgrading our websites. We're having trouble with using the 8.0 version of the ReportViewer control with IIS 7 in Integrated mode. Below is a summary of our previous setup and what we're attempting to upgrade/change to.

Our previous setup:IIS 7 Classic Pipeline Mode.Net Framework 3.5 ReportViewer 8.0 Local Mode (control used within websites - no separate Sql Reporting Server)

Attempting to upgrade to IIS 7 Integrated Pipeline Mode.Net Framework 4.0 ReportViewer 8.0 Local Mode - NO CHANGE

Our sites are all working fine except for the use of the ReportViewer control. We're not ready to upgrade our reports to version 10.0 so we wanted to continue using version 8.0.

Since we're now using the Integrated pipeline mode of IIS7, we changed our root level web.config files of our websites to contain the handler for the report viewer in the system.webServer/handlers section instead of the system.web/httpHandlers section.We're receiving the following error when attempting to access a page that contains the ReportViewer control,

Microsoft.Reporting.WebForms.ReportViewerHandlerNotRegisteredException: The Report Viewer Web Control HTTP Handler has not been registered in the application's web.config file. Add <add verb="*" path="Reserved.ReportViewerWebControl.axd" type


Microsoft.ReportViewer.WebForms, Version=, Culture=neutral,

PublicKeyToken=b03f5f7f11d50a3a" /> to the system.web/httpHandlers section of the web.config file.We can't add the handler to the system.web/httpHandlers section of the web.config file since we're running in IIS7 Integrated Pipeline Mode.

We've tried both manually modifying the web.config file to include the handler in the system.webServer/handlers section as well as adding it via IIS. Both methods produce the same result.So, is version 8.0 of the ReportViewer control not compatible with IIS7 in Integrated Pipeline Mode? If it is compatible, what are we doing wrong? If it is not compatible, is version 9.0 of the ReportViewer control compatible?Here are the pertinent sections of our web.config files:

HttpContext.Current Doesn't Exist In IIS7 Integrated Mode?

Sep 16, 2010

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" ?>

HttpHandlers / Modules :: HttpModule Broken After Migration To IIS7 (integrated Mode)?

Jul 27, 2010

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"/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.

Web Forms :: Breakpoints Are Not Executing When Run In Debug Mode?

When I run debug and click the button it never picks up on the break point. What's up? Is there something about image buttons that I'm not aware of?

Example of one image button and click button sub:



Update: I've just now noticed that whenever I put a breakpoint anywhere in this project and run debug, it never executes the breakpoint at all. Do I need reinstall Visual Studio?

Visual Studio :: System.TypeInitializationException When Executing A 4.0 Web Application In Debug Mode?

Feb 11, 2011


There are plenty other similar static methods defined within the class.

When does it fail: ONLY when the solution is compiled in 'DEBUG' mode. Everything works fine in 'RELEASE' mode.

What have I already tried:

1. Including a static constructor inside 'Utility' class - FAILED

2. Marking 'Utility' class with 'static' keyword: FAILED

3. Changing platform target from 'Any CPU' to 'x64': FAILED

As highlighted above, the issue is really not with VerifyPassword() method per se. Rather it is with the instantiation of 'Utility' type. That's why an exception is thrown from the constructor. Since 'VerifyPassword' is it is the first static method called, it appears in the stack. Just for the sake of proving that, I removed the call to VerifyPassword and returned 'true' instead. That way I was able to login to the application (no password verification), but failed at a later stage where I had called the Utility class on another method, namely Utility.ValidateSKUAdjustment(txtCurentMonthM1.Text).
