Ok, it now work fine. I just make a little modification to the code with : response.setHeader(Content-Disposition,inline; filename=+archive); If i put attachment and not inline i can't manage to have the native contents embemded in my page for data such as images.

Re: How to specify a name for a content beeing served by s servlet
Cédric, You could write something like this, as we have done. /some-path/getbyidservice/93847572934/foo-filename.jpg We have done this in Perl, and will be attacking this in servlets 1st week February. This allows the browser to cache (if allowed by headers) and to have the extension/filename set as intended. If you want to encode more details in the request, i don't see why you cannot introduce delimiters into the id path element. -jason pyeron -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- - - - Jason Pyeron http://www.pyerotechnics.com - - Owner Lead Pyerotechnics Development, Inc. - - +1 410 808 6646 (c) 500 West University Parkway #1S - - +1 410 467 2266 (f) Baltimore, Maryland 21210-3253 - - - -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- This message is for the designated recipient only and may contain privileged, proprietary, or otherwise private information.

Re: How to specify a name for a content beeing served by s servlet
Yes, This is exactly what I did to send .csv files to the client with the correct name of the file rather than the called servlet as the default filename. Worked like a charm on both IE and Netscape.
