Hi Difference between ASP and ASP.Net:- In ASP, ASP engine executes server-side code, which is always through an interpreter (JScript or VBScript). When a traditional ASP page is requested, the text of that page is parsed linearly. All content that is not server-side script is rendered as is back to the response. All server-side script in the page is first run through the appropriate interpreter (JScript or VBScript), the output of which is then rendered back to the response. This architecture affects the efficiency of page rendering in several ways. First, interpreting the server-side script on the fly.As a side effect, one common optimization for ASP applications is to move a lot of server-side script into precompiled COM components to improve response times. A second efficiency concern is that intermingling server-side evaluation blocks with static HTML is less efficient than evaluating a single server-side script block, because the interpreter has to be invoked over and over again. Thus, to improve efficiency of rendering, many ASP developers resort to large blocks of server-side script, replacing static HTML elements with Response.Write() invocations instead. Finally, this ASP model actually allows different blocks of script within a page to be written in different script languages. While this may be appealing in some ways, it also degrades performance by requiring that a particular page load both scripting engines to process a request, which takes more time and memory than using just one language. But in ASP.NET, In contrast, ASP.NET pages are always compiled into .NET classes housed within assemblies. This class includes all of the server-side code and the static HTML, so once a page is accessed for the first time (or any page within a particular directory is accessed), subsequent rendering of that page is serviced by executing compiled code. This eliminates all the inefficiencies of the scripting model of traditional ASP. There is no longer any performance difference between compiled components and server-side code embedded within a page they are now both compiled components. There is also no performance difference between interspersing server-side code blocks among static HTML elements, and writing large blocks of server-side code and using Response.Write() for static HTML content. Also, because the .aspx file is parsed into a single code file and compiled, it is not possible to use multiple server-side languages within a single .aspx file. New Page Directives In ASP you must place all directives on the first line of a page within the same delimiting block. For example: But in ASP.NET, you are now required to place the Language directive with a Page directive, as follows: You can have as many lines of directives as you need. Directives may be located anywhere in your .apsx file but standard practice is to place them at the beginning of the file. Several new directives have been added in ASP.NET.

Hi Vineet, Differences: 1.Process Isolation ASP is run under the inetinfo.exe(IIS) process space and hence susceptible to application crashes as a result the IIS needs to be stopped or restarted. ASP is related to the process isolation setting in IIS. But, ASP.Net The ASP.NET worker process is a distinct worker process, aspnet_wp.exe, separate from inetinfo.exe ( IIS process), and the process model in ASP.NET is unrelated to process isolation settings in IIS. Note :- IIS is still the entry point to a ASP.NET application 2.Non-MS Platform Support Classical ASP had no mechanism of running itself on non- Microsoft technology platforms like the 'The Apache Web Server' But, ASP.NET ASP.NET could be run on non-Microsoft Platforms also. Cassini is a sample Web server produced by Microsoft which, among other projects, has been used to host ASP.NET with Apache . 3.Multi Language Support in WebPage In ASP only two languages were available for scripting VBScript and Jscript/Javascript. But in ASP.NET We are no longer constrained to the two scripting languages available in traditional ASP: Any fully compliant .NET language can now be used with ASP.NET, including C# and VB.NET. Thanks.
