[jboss-jira] [JBoss JIRA] (WFLY-2259) JSESSIONID in URL should be lowercase

JSESSIONID in URL should be lowercase ------------------------------------- Key: WFLY-2259 URL: https://issues.jboss.org/browse/WFLY-2259 Project: WildFly Issue Type: Bug Security Level: Public(Everyone can see) Components: Web (Undertow) Affects Versions: 8.0.0.Beta1 Reporter: Christian Kaltepoth Assignee: Stuart Douglas Fix For: 8.0.0.CR1 I know this looks like a very minor thing, but this was causing trouble for me in some integration tests, so I think I should bring it up here. Wildfly appends *{{JSESSIONID}}* instead of *{{jsessionid}}* to the URL when encoding the session id (uppercase instead of lowercase). IMHO the spec requires it to be lowercase. From Servlet 3.1 spec: {quote} *7.1.3 URL Rewriting* The session ID must be encoded as a path parameter in the URL string. The name of the parameter must be jsessionid. Here is an example of a URL containing encoded path information: {code}http://www.myserver.com/catalog/index.html;jsessionid=1234{code} {quote}
