What I tend to do in this instance is keep all but config options in an
external js file.
The at the top of my jsp (applicable to ASP as well) page I have a Global
Config oject
var ApplicationConfig = {
sessionId : <c:out value="${sessionId}" default:'null'/>,
otherValue : <c:out value="${otherValue}" default:'null'/>,
}
Then in my sepearte JS file I can use these via ApplicationConfig.sessionId.
It permits dynamic variables while keeping most of the Javascript off the page.

Pick your poison:
- Use inline JS if you want dynamic variables
- Lose the dynamic variables if you want external JS
Your IIS server sees as request for ".js" (and ".css" and ".html" etc
etc) and passes it right back to the client as *plain text*, there is
no ASP processing applied to it
