>create a "pdf icon" only when the
implementation of the external.png is
How do you want to detect whether an URL points to a
PDF-file (i. e. not
something that Internet Exlporer would executeable but is called
"something.pdf")

Hendrik,
as the subject says: I only propose to show an icon, I did not propose to scan file types
of something extern. If that file is internal i.e. linked via the [[media:filename.pdf]]
notation, then the server has potentially the chance to check the "magic" byte
of that file; if it is external, i.e. [
http://server/filename.pdf|othername], you can only
argue from the filename.pdf that it pretends to be "PDF" . If you see a security
problem, what does the (PDF.png vs. external.png ?) icon change in this respect ?
Nothing; but with my proposal you could even have ***two*** different PDF icons, a green
"secure" icon for internal (filetype scanned) [[media:filename.pdf]] files and a
red "insecure" alerting one ("extern; probably PDF") for the others.
This is just meant as an ad-hoc proposal to show you the positive possibilities of my
proposal.
Does this answer satisfy you ?
