.NET in js include file

Question

Can I get print data in my .js files before sending them to the client? I want to be able to print the session id into a variable to use in getting around the flash cookie bug. Here's my code:

//Add our custom post-params
                var auth = "<% = If(Request.Cookies(FormsAuthentication.FormsCookieName) Is Nothing, String.Empty, Request.Cookies(FormsAuthentication.FormsCookieName).Value) %>";
                var ASPSESSID = "<%= Session.SessionID %>";

                this.setPostParams({
                    ASPSESSID: ASPSESSID,
                    AUTHID: auth
                });

That shows up exactly the same way in my js file. I want the server to process the code!

I think you want to use immediate if. Like:

var auth = "<% = iif(Request...
