Ah. I use nsWebBrowserPersist to download the file to disk. (I sent a code sample for that to this list about a month ago - I don't know if there's an archive or not.)

But the problem is that the zip is the GET RESPONSE from a servlet! I mean: function getZip(){ netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect"); var mGET = new XMLHttpRequest(); mGET.open("GET","/whatever.zip"); mGET.onload=function(){ if (mGET.status==200) { netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect"); // here goes the zip handle // here you have nsInputStream with the zip bytes // but how do you get the zip contents from the response nsInputStream? } else{ alert(""+mGET.status + " : " + mGET.statusText); } } mGET.send(null); } M.
