Serving a modified file

[cadbilbao]

Hi!

I'm using Tomcat 3.2.3.

Into my '$TOMCAT_HOME/webapps/ROOT/' directory, I've got 'myfile',
and I want users get a modified version of it.

I mean. 'myfile' is a plain-text file, and I want to remove the
first line, so users can not visualize it. Besides, I want to
add an extension, so I try to serve 'myfile.txt'.

What must I do?

+ Must I create a EJB?
+ Must I create a /temp/myfile.txt?

Regards,
