How to open external URL that requires certificate

[Heath Aiken]

I'm just learning Node.js / node-webkit, and have whipped up a little node-webkit application that I intend to use as a 'control center' for opening and controlling various company sites / applications.

One of these sites requires a client certificate. When I open the site in IE, Chrome, etc. a dialog pops up asking me to select / verify the proper certificate (which was previously installed via IE). I am not an expert on certificates, so if this is obvious, please bear with me: Is there a way way to set a flag or a path to the certificate in the options for that window?

This stuff is a little bit over my head, and I may be looking at it the wrong way. Anyone else run into a similar issue?
