Protect a specific php file

[voidandany]

It seems resolved, during my test I have downloaded the php file and my
browser put it in cache so every time the web server respond the browser
serve the file in cache.
It explain why it worked with IE (file not in cache) but not with
Chrome...

Sorry for losing your time and many thanks to you Francis for the time
you spent making test
