Hi ammad,


The reason for that is that the browser has NOT been given any information that the data being received is NOT plain text or HTML.

You would need to issue a content-type header to tell the browser that the data is NOT understandable and ask the user to download it.

In PHP this would be ...

<?php
header('Content-type: application/octet-stream');
...
?>

You need to do something similar.

But that is only have the answer.

IE will sometimes use the extension of the filename and use that as a type. WHich is a pain.

Try issueing the header() (Not sure what the Java mechanism is).

You will normally also need to issue the header() before ANY other output.

Regards,

Richard Quadling.

You have to use:

response.setContentType ( "application/octet-stream" ) ; // or whatever you want. For unknown, you can use application/x-stream
response.setHeader ( "Content-disposition", "attachement; filename=\"Filename.extension\"" ) ;

As a matter of fact, if you are using IE 5 - the 'e' is there. There was a bug ;-) which they corrected in SP 2 for IE 5. IE 6 accepts the correct spelling "attachment". Netscape seems to accept both I guess. Not sure what the target browser is in this case ;-) I guess we should try both.

Many people can make spelling mistakes with referer ;-) it still 'looks' as though it is correct.

One can actually use the "User-Agent" request header to check what the client browser is and accordingly use "attachement" for some special cases and use "attachment" as the default ;-)

Any reason for the B grade? You can ask for more clarification if you want.
