ASPX
editASPX is a text file format used as web-form pages in Microsoft .NET environment. In programming jargon, the ASPX file contains only static HTML code where the developer places all the required form fields and text content for the web page. The dynamic code that involves request and response from the server are placed in html page with a tag or block <% -- dynamic code -- %> which is similar to other web development technologies such as ASP, JSP etc.
When projects are developed with Microsoft .NET technology, the form files or web pages with html code are renamed into ASPX format with dynamic code inserted inside the tag. When a client requests information from the server, for instance, checking the ticket price from a travel agent, the ASPX page with text content and form fields gets information from the client and passes on the information to the server. With the help of the dynamic code inside the tag, the client gets the response or the information (ticket price) requested from the server.
The ASPX and other resource files are placed in Microsoft’s IIS Server. When a client requests information, the .NET framework parses and compiles the file into a .NET class and sends the response. Unlike other web development technologies, that compiles every time when responding the client, the ASPX files are compiled only for the first time when accessed and are re-used to reduce response time.
