Filter access to response object [was Re: domain-wide sessioncookies?]
On Mon, 24 Mar 2003 14:10:59 -0800 (PST), Craig R. McClanahan [EMAIL PROTECTED] said: Sharing a session across virtual hosts violates the Servlet spec (Section 7.3 - HttpSession objects must be scoped at the application (or servlet context) level and Section 3.6 - Servlet contexts can not be shared across virtual hosts), so you should not really be surprised to find the logic for setting up a session cookie be hard coded in the manner you describe. Okay, you're right, that violates the spec. So please forget I asked (grin). Instead, what is now troubling me is that it seems that Tomcat adds HTTP headers to the response object *after* all filters have been applied. AFAICT, the spec does not explictly comment on this and so I'm assuming it is a detail left to the implementator. Here's my problem: - I have a single filter that essentially does: doFilter(...) do stuff to request object... chain.doFilter(..); do stuff to response object... } however, it seems that Tomcat adds response headers _after_ the filter, is there a reason for that? I'd like to manipulate *ALL* the headers in the response object with my filter... Adi - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Since Tomcat adds its last headers when the response is committed (because otherwise they would not be able to be added), why not just add a call to: response.flushBuffer(); before the line that says: do stuff to response object... ?

Maybe I wasn't clear -- I'd like to manipulate all the response headers at the point I say do stuff to response object... and if I call response.flushBuffer() right before that, I no longer can manipulate the headers in the response object (empirically verified under Tomcat 4.1.20).
