I want to know what is .do extension in web pages. Is it a standard extension, or, if it's not, can we change the extension (like client-login.php
to client-login.do
and still run as PHP)?
Thanks.
.do comes from the Struts framework. See this question: Why do Java webapps use .do extension? Where did it come from? Also you can change what your urls look like using mod_rewrite (on Apache).
