Which programming language has extension .do

Just wondering whic开发者_StackOverflow中文版h programming languages is used on the web pages with the extension ".do"

According to FileInfo, the file extension is for Java Servlets.

Strictly speaking, you can't tell for sure just by looking at the extension. I can configure a web server to interpret *.do URLs as referring to PHP files or even executables and run it accordingly. In fact, *.do URLs may not even refer to files at all! It really does depend on how the server is configured.

That is typically not so much a programming language feature but a framework feature: apps developed with Apache Struts (see http://struts.apache.org/) typically use that extension.

.do extension is used to build a J2EE enterprise application using Struts and dao factory method that is latest technology framework to build EE applications. It is much faster and efficient than JSP and JSF.
