From crisis late 90's, ASP (Active Server Page) has been selected many programmers and developers to build web applications on the server using the Windows operating system. ASP has demonstrated its advantages to the programming model simpler procedures, efficiency of the COM object: ADO (ActiveX Data Object) - data processing, FSO (File System Object) - Working with system files ... and at the same time, the ASP also supports multiple languages: VBScript, JavaScript. It is these advantages, ASP has loved for a long time.
However, ASPs are still some outstanding problems such as ASP and HTML Code error, making the process very difficult to write code, expression and unclear presentation code, limiting the ability to reuse code. Besides, when deployed installations, due to be compiled before they can be easily lost source code. Also, there is no support ASP cache, not precompiled should somewhat limited on speed of execution. Sign the treatment process difficult ...
In early 2002, Microsoft introduced a technique quite new Web programming initially called ASP +, the official name of the latter is ASP.Net. With ASP.Net, not only does not require you to know HTML tags, web design, but it also supports object-oriented programming in the powerful process of building and developing Web applications.
ASP.Net is a programming techniques and develop web applications in the server (server-side) based on Microsoft's .Net Framework.
Most programmers who are new to the web began to learn the techniques of the Client (Client-side ), such as HTML, Java Script, CSS (Cascading Style Sheets). When a web browser requests a web page (the technical side of the site used by the client), the Web server to find the site requested by the client, and then sent to the customer. Customers get the results returned from the server and displayed on the screen.
ASP.Net programming techniques used in the server side is completely different, in the server side code (for example, the code in the ASP) will be compiled and executed in the Web server. After Server read, compile and execute, the results automatically converted to HTML / JavaScript / CSS and returned to the customer. All order processing is done in ASP.Net Server and technique called server-side programming.
