Static Resources...

I’m trying to get a bunch of XLS and PDFs uploaded...

Regarding the "Extensions"... is this supposed to be a single value? Or can you give it multiple values? Does it have to be comma-delimited?

I think it has to be either .pdf either .xls, so when you resource is generated it will have this path: www.yoursite.com/alias.pdf
I am not sure if the extension needs the . or not.

Exactly.... the label there really needs to be more clear. Should it include the dot? Can you use commas to separate multiple extensions (e.g. ".jpg, .jpeg")?

I am puzzled on why you want to use multiple extensions?
A resource can be either jpeg or jpg; it can’t be both at the same time

Maybe I don’t... I was just thinking of efficient ways to map a content/mime-type to multiple extensions. Maybe there’s not a good use case for needing multiple extensions as far as the MODx manager is concerned.
