How to enable View Current Requests in IIS

View Current Request in IIS enables to displays the current running requests in a worker process. Several fields provide data to investigate performance issues; for example, the URL, Client IP, Pipeline Module State and Module Name, and the Time Elapsed for a request.

Here is how it can be done. 

1. To enable the View Current Requests action in the Worked Processes feature, the Request Monitor feature must be enabled. The following steps are typical among later Windows operating systems:
1. Open the Server Manager.
2. Select Roles and locate the Web Server (IIS) role.
3. Click Add Role Services .
4. Locate the Health and Diagnostics section then select Request Monitor .
5. Click Next and complete the wizard.
2. Once enabled, open IIS Manager and select the Web server.
3. In the Web Server Home Features view, go to the IIS section and select and open the Worker Processes feature.
4. Select the Desired worker process then, in the Actions pane, click View Current Requests (or right-click on the Worker Process and select View Current Requests 

Hope this helps 😀!!

How to View Running Web Requests in IIS

When website performance suddenly becomes worse, there may be many potential causes. Gathering information about the current requests being handled by the worker process can help to identify issues impacting performance.

The Internet Information Services (IIS) Manager provides a server-level Worker Processes feature that manages "a list of worker processes running in application pools on a Web server." The information provided includes the Application Pool Name, Process ID, State of the process, CPU percentage, Private Bytes, and Virtual Bytes

Additionally, if enabled, the View Current Requests action is available. The View Current Requests displays the current running requests in a worker process. Several fields provide data to investigate performance issues; for example, the URL, Client IP, Pipeline Module State and Module Name, and the Time Elapsed for a request.

Although, this may also show a bunch of web requests that are queued up and not directly lead you to the root cause.

One of the first things you should do is see which web requests are currently executing. This may help you identify a specific URL that is causing the problem.

Via the IIS User Interface

Via the IIS management console, you can view the running worker processes. You can view which IIS application pool is causing high CPU and view the currently running web requests.

After selecting “Worker Processes” from the main IIS menu, you can see the currently 

running IIS worker processes.

If you double-click on a worker process, you can see all of the currently executing requests.

Here’s an example from one of our servers. You can see that each request is in different parts of the ASP.NET pipeline and currently executing different HTTP modules.

Difference between HTTP.SYS and WAS in IIS

HTTP.SYS (Hypertext Transfer Protocol Stack) is the kernel level components of IIS. All client request comes from client hit the HTTP.Sys of Kernel level. HTTP.SYS then makes a queue for each and every request for each and individual application pool based on the request.

Whenever we create any application pool IIS automatically registers the pool with HTTP.SYS to identify the particular during request processing.

WAS(Windows Activation Service) is a new feature of IIS, that allows all the features of the Windows Communication Framework stack, like non-HTTP channels and other stuff.

IIS is the web server that hosts the services that are activated via WAS.

WAS - is the new process activation mechanism that ships with IIS 7.0. WAS builds on the existing IIS 6.0 but is more powerful because it provides support for other protocols besides HTTP, such as TCP and Named Pipes.

For more details, go through IIS architecture

405 - HTTP verb used to access this page is not allowed

We get the above error when we use PUT verb when we access RESTFUL web services.

For this to work, The web site had to continue to enable WebDAV, but the web application needed to turn it off in order to support PUT and DELETE in its REST API.

Below are the approaches I followed to solve my problem.

Procedure 1:

1. In the IIS Manager, select the application that needs to support PUT.  
2. In the Features View, find WebDAV Authoring Rules.  Double-click it, or select Open Feature from the context menu (right-click).
3. In the Actions pane, find and click on WebDAV Settings....
4. In the WebDAV Settings, find Request Filtering Behavior, and under that, find Allow Verb Filtering.  Set Allow Verb Filtering to False.
5. In the Actions pane, click Apply.

Procedure 2:

1. Go to IIS Manager.
2. Click on your app.
3. Go to "Handler Mappings".
4. In the feature list, double click on "WebDAV".

5. Click on "Request Restrictions".
6. In the tab "Verbs" select "All verbs" .

7. Press OK.

Hope this helps!

C#: How to Get Machine name of the webserver

Here is how you can do using C#,

Response.Write("machinename " +System.Environment.MachineName +"<BR>" )

This gives you name computer where your webserver is located.

If you need with the domain name here is how you can achieve using the following code snippet:

You need to import following namespace to use this,

using System.Net; 

public static string GetServerMachineName()
{            
    string domainName = System.Net.NetworkInformation.IPGlobalProperties.GetIPGlobalProperties().DomainName;
    string hostName = Dns.GetHostName();
    string sysdn = "";
    if (!hostName.Contains(domainName))
        sysdn = hostName + "." + domainName;
    else
        sysdn = hostName;

    return sysdn;
}

Happy Coding

How to add MIME types in Web.config on hosted Servers, Go Daddy, IIS 7 etc.

Ever wanted to add a custom mime type to your Web server?  I ran into this issue the other day when I tried to serve up .otf files related to fonts on my Web server and  I got this error: 404.3 error - mime type missing!

Thankfully, adding mime types is easier than ever thanks to the all-new distributed configuration option, which allows for IIS7 configuration to be stored in web.config files, along with asp.net configuration, to be deployed with your content. 

I'll show how easy it is to add mime types to your Web server.  This method will work on any IIS7 web server, and it will be ignored on all non-IIS7 web servers, so it should be safe to do no matter the type of application or content.  Since the <staticContent> section is delegated by default, the configuration snippets below should 'just work' on all IIS7 Web sites. 

1. Open or edit the web.config in your site home directory.
2. Add the following section in configuration section under web server.

<system.webServer>   
    <staticContent>
      <mimeMap fileExtension=".otf" mimeType="font/otf" />
    </staticContent>
</system.webServer>

This works even on Go Daddy hosted server also. You can add as many file times you want allow in this static content section.  For example these few MIME types you can add if you want on your Web server

<mimeMap fileExtension=".m4v" mimeType="video/m4v" />
<mimeMap fileExtension=".ogg" mimeType="audio/ogg" />
<mimeMap fileExtension=".oga" mimeType="audio/ogg" />
<mimeMap fileExtension=".ogv" mimeType="video/ogg" />
<mimeMap fileExtension=".webm" mimeType="video/webm"/>
<!-- For silverlight applicaitons -->
<mimeMap fileExtension=".xaml" mimeType="application/xaml+xml" />
<mimeMap fileExtension=".xap" mimeType="application/x-silverlight-app" />
<mimeMap fileExtension=".xbap" mimeType="application/x-ms-xbap" />

Hope this helps

What is a MIME type?

There are times when you would want the IIS web server to serve a file that has an extension that it does not recognize. That is, a file whose MIME type has not been defined. In such a case, IIS would return http error code, 404.3 as shown below.

HTTP Error 404.3 – Not Found
Description: The page you are requesting cannot be served because of the Multipurpose Internet Mail Extensions (MIME) map policy that is configured on the Web server. The page you requested has a file name extension that is not recognized, and therefore is not allowed.

MIME stands for Multi-purpose Internet Mail Extensions. MIME types form a standard way of classifying file types on the Internet. Internet programs such as Web servers and browsers all have a list of MIME types, so that they can transfer files of the same type in the same way, no matter what operating system they are working in.

A MIME type has two parts: a type and a subtype. They are separated by a slash (/). For example, the MIME type for Microsoft Word files is application and the subtype is msword. Together, the complete MIME type is application/msword.

Here is the list of available MIME types that you can add and configure on IIS

Hope this is useful.

List of MIME Types with Content types

There are times when you would want the IIS web server to serve a file that has an extension that it does not recognize. That is, a file whose mime type has not been defined. In such a case, IIS would return http error code, 404.3. For the web server to serve the file with that new extension, you need to create a mapping between that extension and the MIME type.

Internet Information Services (IIS) 7.5 Express

Microsoft has released final version of it’s so called lighter version of IIS 7.5 called as “IIS 7.5 Express” which makes developers to utilize the features of IIS 7.5 in Windows XP and above Operating system environments. IIS 7.5 Express is a simple and self-contained version of IIS 7.5 that is optimized for developers. IIS 7.5 Express enhances your ability to develop and test web applications on Windows by combining the power of IIS 7.5 with the convenience of a lightweight web server like the ASP.NET Development Server (also known as Cassini). IIS 7.5 Express is included with Microsoft Web Matrix, an integrated suite of tools designed to make developing web applications on Windows simple and seamless. IIS 7.5 Express can also be used with Visual Studio 2010 as a powerful alternative to Cassini. The benefits of using IIS 7.5 Express include:

• The same web server that runs on your production server is now available on your development computer.
• Most tasks can be done without the need for administrative privileges.
• IIS 7.5 Express runs on Windows XP and all later versions of Windows.
• Many users can work independently on the same computer.

Download: IIS 7.5 Express Final

"LM/W3SVC/1/root/webapplication" already exists. Please choose a different alias.

This is the very common error that any web programmer can face when we web share a folder.The solution is to remove the virtual directory entry from the IIS window. But what if the entry does not exist in the IIS window. This situation comes when you delete/move the folder from the c:\inetpub\wwwroot folder before deleting its virtual directory. So the solution is to remove the virtual directory entry from the IIS.

Here is the Procedure to remove virtual directory entry from the IIS database?

Here are the 3 ways how we can do this.

1. Use following command

Syntax
iisweb /delete WebSite [WebSite...][/s Computer [/u[Domain\]User/p Password]]

You can get more help on this from here.

2. Recreate the folder with the same name in the c:\inetpub\wwwroot and then restart the IIS (use iisreset.exe). You will see the virtual directory with the same name in the IIS window, now remove the virtual directory from IIS.

3. Use the following command by opening the command prompt.
c:\inetpub\wwwroot\cscript adsutil.vbs DELETE "W3SVC\1\root\"

For more information on adsutil.vbs.

Hope this helps.
