Java – how to get HttpServletRequest in HttpSessionListener?

How do I access request headers from sessionlistener?

I need to set a timeout when creating the current session The timeout needs to change according to the header in HttpServletRequest I already have a sessionlister (implementing httpsessionlister) to record the creation and destruction of new sessions. It seems to be the most reasonable place to set timeout

I tried the following, but it always sets CTX to null

FacesContext ctx = FacesContext.getCurrentInstance();

Solution

HttpSessionListener does not have access to the request because it is called to notify session destruction when there is no request

Therefore, filters or servlets are a better place to check requests and specify session timeouts
