Re: manipulating http headers with rivet

This command will allow your users' browsers to do estimated download  
times:

         headers set "Content-Length" [file size $fileName]

FWIW, my implementations of Content-Disposition have the filename  
included inside filename="filenamehere.xyz" rather than just having  
the filename as the value of the Content-Disposition field

    Thank you Daniel, I had fixed the 'Content-Disposition' issue after 
I found a
working example in a PHP programming manual (and it wasn't an easy job
to find a manual that cleanly explains the headers programming). The
'Content-Length' header was already ok.

Yesterday I started to work on a page to be included in the documentation
that recaps the experience I made.
