HTTPHandler and HTTPModule in ASP.NET

If you want to implement pre-processing logic before a request hits the IIS resources. For instance you would like to apply security mechanism, URL rewriting, filter something in the request, etc. ASP.NET has provided two types of interception HttpModule and HttpHandler .   The web server examines the file name extension of the requested file, and determines which ISAPI extension should handle the request. Then the request is passed to the appropriate ISAPI extension.  For Example When an .aspx page is requested it is passed to ASP.Net page handler. Then Application domain is created and after that different ASP.Net objects like Httpcontext, HttpRequest, HttpResponse. HTTPModule: -    It's just like a filter. The Modules are called before and after the handler executes . -    HTTP Modules are objects which also participate the pipeline but they work before and after the HTTP Handler does its job, and produce additional serv...

Connected and disconnected architecture in ADO.Net with Example

Connected Architecture of ADO.NET The architecture of ADO.net, in which connection must be opened to access the data retrieved from database is called as connected architecture. Connected architecture was built on the classes connection, command, datareader and transaction.  Connected architecture is when you constantly make trips to the database for any CRUD (Create, Read, Update and Delete) operation you wish to do. This creates more traffic to the database but is normally much faster as you should be doing smaller transactions. Disconnected Architecture in ADO.NET The architecture of ADO.net in which data retrieved from database can be accessed even when connection to database was closed is called as disconnected architecture. Disconnected architecture of ADO.net was built on classes connection, dataadapter, commandbuilder and dataset and dataview. Disconnected architecture is a method of retrieving a r...

What is the Difference between Overriding and overloading?

Overloading is defining functions that have similar signatures, yet have different parameters.  Overriding is only pertinent to derived classes, where the parent class has defined a method and the derived class wishes to override that function. Overriding Overloading Methods name and signatures must be same. Having same method name with different Signatures . Overriding is the concept of runtime polymorphism Overloading is the concept of compile time polymorphism When a function of base class is re-defined in the derived class called as Overriding Two functions having same name and return type, but with different type and/or number of arguments is called as Overloading It needs inheritance. It doesn't need inheritance. Method should have same data type. Method can have different data types Method should be public. ...
