RE: [PHP] MSIE problem with binary file download over SSL

Are you using sessions? There is a "feature" in IE that'll mess up downloads over SSL when the session sends it's session.cache_limiter value. If it's set to "nocache" then the download does not work. Setting it to "none" or empty will allow you to do the file download. ---John W. Holmes...
