Version 1.2.1 of XOM, the XML parsing Java library written by Elliotte Rusty Harold is released.

To force HTTP download of a dynamically generated content, I usually set the HTTP header Content-Type to application/octet-stream. This forces the browser to display the Save dialog box. But this has the limitation of sending the wrong content-type even when we know the correct one. Recently I discovered another HTTP header which solves this problem. This is the Content-Disposition header. This can take following two vales:

1. inline: This will render the content inline in the browser.
2. attachment: This will force the browser to display the Save dialog.

When generating dynamic content, it is also recommended to specify proper filename. This file name can also be specified as a parameter to Content-Disposition header. An example:

Content-Disposition: attachment;filename=document.pdf

 
Content-Disposition is covered in RFC 2183.
