jscript

I'm trying to provide a link to the attachment of a note through the client-side JScript. The standard MS-made Notes component does this through the following url:

[serverurl]/[appname]/Activities/Attachment/download.aspx?AttachmentType=5&AttachmentId={blahblahblah}&IsNotesTabAttachment=1&CRMWRPCToken=blahblahblah&CRMWRPCTokenTimeStamp=blahblahblah

The problem is that I don't know how to get the Token or TokenTimeStamp, so I'm receiving an Access Denied error ("form is no longer available, security precaution, etc").

The only other way I can think of doing this is through the OData endpoint, but that would at best get me a base64 string that I still would have translate into a filestream to give to the browser (all of which seems like it would take forever to implement/figure out).

I've found a few other posts that describe the same thing, but no one has answered them:
