Download Image Component issue.

joe_pat

Hi ,

We have developed a dynamic java component component which will get the transitioned image from mediabin. And we will have a link "Download here" that allow users to download images. It works fine regarding from functionality point of view.

Now problem is like this ....

When the user clicks on the link the image is opened in the browser and the user gets confused to save the file .So, we want to "Force save-as dialog to download ". I planed to use javascript .But problem it works fine with only IE.

So the alternate option i found is to use server side script to set the Content-disposition: header, which tells the browser that regardless of the file's content type, the proper treatment is to save it to disk. And set the content-type to application/octet-stream or application/x-download.

Options are like this i can either use Perl/CGI or jsp. I am not sure which one will works better .

My Question is like this .Can we call a Perl/CGI or jsp when i users clicks on that link?

If it is Perl where do i keep the script ? If it is jsp where should i place the jsp file on the server?

My image path is generated dynamically so i have to pass the path as parameter to the scripts..

Am i going in a right direction ...

Here is the sample Perl code i want to use .

use CGI;
my $q = CGI->new;
open(my $DLFILE, '<', "path/to/your/filename");
print $q->header(-type => 'application/x-download',
-attachment => 'filename',
'Content-length' => -s "path/to/your/filename",
);

binmode $DLFILE;
print while <$DLFILE>;
undef ($DLFILE);


Thanks in advance..
