<?php highlight_file(__FILE__); ?>
The page can be viewed in browser as given below.
The firebug says that they send two request for the file "no-file".
I just removed the first script-tag. That time, they are sending only one request for the "no-file"
why are they sending two request for a 404 file?
NB: There is no file with the name "no-file" in my system and the "empty.js" is an empty file.
