    Unhappy File Transfer with JavaScript

    Hi,

    I am trying to use javascript to download a binary file when a button is clicked, using XMLHTTPRequest/HTTPRequest object.

    I searched google, but I couldn't find anything recognizable. Please let me know if you have any tutotials or sample code.

    PS: I did file code to read xml files using HTTPRequest object; just am not sure how to implement that for binary file and have the browse prompt the user to save the file.

    Thanks,
    -Spell

    You can not prompt save with the XMLHttpRequest object.

    Set a hidden iframe to the file source and the browser should prompt save automatically. (that is if the borwser is set up not to handle that type of file)

    Thanks....is iframe support available in IE and Mozilla/FireFox? I thought iframe is being removed from the XHTML Specification?
