I'm thinking about stroring my .js files on a windows server, but actually using and implementing them on pages on a Linux server.

The reason I'm thinking along these lines is because I'd like to dynamically create the .js files from data in xml files using ASP.

My question is, To what extent are there going to be time and performance penalties taking this approach? How can I start to assess the pros and cons of calling .js files on another server and how much will it slow page rendering?
