问题
I have a link being generated that looks like so:
<a target="_blank" title="Test" href="file:///c:/test.xls">Test</a>
This link is inside an iframe.
When I click on it (in any major browser), nothing happens. Fiddler records no traffic. Pasting the URL into the nav bar works fine - the file download box comes up, and I can download the file no problem.
I've tried every variant of the URL structure (correct and incorrect, colons, slashes, backslashes, etc.) that I can think of.
I'm certain that it's some kind of security restriction, but I can't for the life of me find out what it is or how to get around it. I'm feeling pretty foolish at this point. Any simple explanations?

Sorry, if you are pulling this page off of a server (acessing it as http://), the security settings won't let you link to local content (acess links as file://). I've had this same problem accessing shared .doc files in a wiki. Never came up with a good solution.

Try a colon instead of a pipe ;)
