I don't know if I'm writing in the correct list, but I couldn't find 
anyone else more specific.

I'd like to know how can i to open a .hlp file into the browser when click 
an  href linked to this file.

Some times files start to download an other times they are opened into the 
browser.

Anybody  can explain to me how i can drive this?

In each case it depends on the MIME types that have been set up in the 
client browser, and you can't change these from the Web. You can however 
change the content type that you are sending back to the browser, and you 
should be able to send the data back with a nonstandard or unknown type 
which should trigger the download box.
