问题
Just wondering which programming languages is used on the web pages with the extension ".do"
回答1:
According to FileInfo, the file extension is for Java Servlets.
回答2:
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.
回答3:
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.
回答4:
.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.
