[jbossseam-issues] [JBoss JIRA] Commented: (JBSEAM-3018) Tomcat appending jsessionid to URLs breaks page fragment cache

    [ http://jira.jboss.com/jira/browse/JBSEAM-3018?page=comments#action_12413489 ] 

Christian Bauer commented on JBSEAM-3018:
-----------------------------------------

When a GET hits the server with no session cookie or id, Tomcat creates a new session and sets the cookie:

Set-Cookie: JSESSIONID=2978A7FABFF3DB35BE622290E1294CDE; Path=/

It then also encodes all URLs on a page with jsessionid. Without further proof, this seems to be required because Tomcat, at this point, does not know if the browser supports cookies. So the next GET (with both cookie and URL parameter) is required to decide if cookies are OK or not.

The only solution would be to globally disable URL rewriting and force usage of cookies. You can not disable URL rewriting in Tomcat. It seems to be hardcoded. All workarounds I've found so far are not acceptable (filters that parse HTML, etc).

> Tomcat/JSF encodes URLs and, even if cookies are enabled, sometimes appends a JSESSIONID parameter. If you request a page fragment, your session id is encoded into the rendered URLs. If I then later retrieve that fragment from the cache, I get your session. This is a critical issue, I'll look for a workaround, if that's not possible, we need to document it.
