How to get list of all active HttpModules in ASP.NET?

Here is a quick tips to get the list of all active HTTPModules at runtime. We can get the list of all HttpModules from the web.config or from machine.config file. But, what we need to do if we want to get the list of all active HttpModules during runtime? Yes. We can easily get the details with the help of HttpApplication and HttpModuleCollection Class. If we quickly recall the IIS Process Request [One detailed Article], when a request reaches to worker Process from client browser, First of all Worker process is responsible to start and HttpRuntime by loading ISAPI filter. After that HttpRuntime load an HttpApplication object with the help of HttpApplicationFactory class. Each and every request should pass through the corresponding HTTPModule to reach to HTTPHandler, this list of module are configured by the HTTPApplication. Below is the code snippet by which we can get the list of active HttpModules.

//Get Application Instance from Current Content
HttpApplication httpApps = HttpContext.Current.ApplicationInstance;
//Get List of modules in module collections
HttpModuleCollection httpModuleCollections = httpApps.Modules;
Response.Write("Total Number Active HttpModule : " + httpModuleCollections.Count.ToString() + "
");
Response.Write("List of Active Modules" + "
");
foreach (string activeModule inttpModuleCollections.AllKeys)
{
Response.Write(activeModule + "
");
}

“CompressionEnabled” Session in ASP.NET 4.0

CSS Friendly Menu Control in ASP.NET 4.0

CodeProject
It is very much easier to apply CSS when we have ul,li elements as the HTML content. If we look into ASP.NET Menu Control till Version 3.5, its render as Table-TR-TD Tag. Though Table/Tr/Td is quite useful to display tabular data but sometime creates a big problem when we need to do more work with CSS. To overcome this problem we generally used CSS Friendly adapter to render the ASP.NET Control in ul/li mode.

ASP.NET 4.0 makes the things easier for web developer by providing "RenderingMode" properties. Here we can specify RenderMode of a ASP.NET Menu control. Which define the what will be the HTML Render Content Type. Bydefault mode is "List" which means control will be render as ul/li.

ViewState Control in ASP.NET 4.0

CodeProject
View State is one of the most important and useful client side state management mechanisms. It can store the page value at the time of post back (Sending and Receiving information from Server) of your page. ASP.NET pages provide the View State property as a built-in structure for automatically storing values between multiple requests for the same page.

we generally used “EnableViewState” Properties for both Page Level and Server Control Level to maintain the view state. Till ASP.NET 3.5 Version, Page Level view state control treat as highest priorities. Which means If we set EnableViewState= “False” in page level that will automatically derived by all the server side control. In that case if we set “EnableViewState=”True”” for any server side control will treat as false, as we have defined them “False” in Page Level.Here is one complete article on ASP.NET 2.0/3.5 View State , which may helpful for you

Now, let’s have a look into the changes in ViewState Control in ASP.NET 4.0. There is a massive change in View State Control in ASP.NET 4.0 which is very much helpful for developer also. Asp.net 4.0 added a new property to Page object and server controls called ViewStateMode.

Beginner’s Guide: How IIS Process ASP.NET Request

IIS (Internet Information Server) is one of the most powerful web servers from Microsoft that is used to host your ASP.NET Web application. IIS has it's own ASP.NET Process Engine  to handle the ASP.NET request. So, when a request comes from client to server, IIS takes that request and  process it and send response back to clients

When client request for some information from a web server, request first reaches to HTTP.SYS of IIS. HTTP.SYS then send the request to respective  Application Pool. Application Pool then forward the request to worker process to load the ISAPI Extension which will create an HTTPRuntime Object to Process the request via HTTPModule and HTTPHanlder. After that the ASP.NET Page LifeCycle events starts.

ASP.NET 4.0 Features - MetaDescription and MetaKeywords

ASP.NET 4.0, came up with two new properties inside Page Class, those are MetaDescription and MetaKeyWord. This has been introduce because of make web application Search Engine Friendly. Search Engine looks for Meta tag of our web page to get the details of page contents. In ASP.NET 4.0, we can add these two properties with Page class in Code behind or in Page Directives.
If you want to find out the definition of these two properties, Right Click on Page Class and Click on Goto Definition. This will show you the Meta data information of Page Class as shown in below picture

If we set MetaDescription and MetaKeywords either from Code behind or using Page Directive in aspx page, both will be render as “meta” tag in html code.
The main objective of MetaKeywords and MetaDescription proerties to make your web application SEO friendly. In ASP.NET 2.0, HtmlMeta used to do the same, but in ASP.NET 4.0 make these thing  very simple as we can easily add using Page Class.

My New Article : Exploring Caching : Using Caching Application Enterprise Library 4.1

Enterprise Library caching application Block provides ready to use Caching Framework. This  can be used in various application like

* ASP.NET Web application
* Windows Forms
* Console
* Windows Service
* Enterprise Services
* Web service
Implementing caching using Caching Application Block improve the performance of application as well as reduces the development time and cost. This Application blocks provides all kinds of function like adding, removing, managing expiration of cache.
As caching application block is predefined set of code and that are defined in a framework for that we need install Enterprise Library 4.1 First then we need  to add some reference in to our application. These are Microsoft.Practices.EnterpriseLibrary.Caching.dll and Microsoft.Practices.EnterpriseLibrary.common.dll.

I have published one complete article on Codeproject.com which describe how to use Enterprise Caching Application Block 4.1 . Here is my complete article

Excellent Debugging Features in Visual Studio 2010 Beta 2

The Visual Studio 2010 IDE is simply great and came up with many new features within it. I have found one of the great and innovative features in Debugging style in VS 2010 Professional Beta 2 that is Pin/Unpin Object/Variable Inspect or Data Tip.

while debugging in visual studio we generally used mouse over on the object or variable to inspect the current value. This shows the current data items hold by the inspected object. But this is for limited time, as long as long the mouse is pointed to that object those value will be available. But in Visual Studio 2010 Beta 2, there is a great feature to pin and unpin this inspected value. We can pin as many of any object and there sub object value also. Please have a look into below picture.
Apart from that there are many features like Drag and Drop Tip, Add Comments on tip etc. Here is my one complete article on CodeProject. Please have a look
