Hi Monks

I am using WWW::Mechanize module to extract hyperlinks and download a file from website

I have a small problem to identify the file name of the current page

$temp="https://www.ctslink.com/a/document.html?key=2988562";
$mech->get($temp);
$mech->save_content();
[download]

The above mentioned url is a pdf file link and url has only key value there is no extension or file name, my question is how do i extract the pdf file name? even i used $mech->title() to get title but it seems a null string only

Any Idea...
