What does .action / .event at an end of a url mean?

Question

"https://www.evernote.com/Home.action"

Hi I was browsing Evernote and Mint.com and noticed that they both have .event / .action at the end of the url like above. What is the significance of it? How do you add something like that to an end of a url?

Answer 1

It means that the website is based on Struts2 framework by apache. Struts2 is a popular Java framework for creating Enterprise level java applications. All struts2 based sites have that ".action" ending URL.

This can be changed from the config file.
