Hi, >But I have 2 questions: >1. Where are these header values defined I've not beeen able to find a >good source.
See the HTTP protocol RFC itself for common headers like referrer. Other servers and routers may add custom headers along the way. Your app and other apps can also use custom headers if they wish. >2.

Does referer only apply when hyperlink from another page ? Some browsers, including IE, are known to have bugs regarding the referrer header. Sometimes it's null or not included in the request at all. So your app, if it uses the referrer header, must be tolerant of these bugs. What about a history.go(-1) alternative to the referrer header?
