I have run into a strage cookie processing bug with tomcat 5.5.17 bundled with JBoss-4.0.4.GA. Basically, if the cookie is in xml format and is set on the browser, the cookie is set just fine with double quotes properly esacped etc. But, when this cookie is sent back to the server, the cookie value gets mangled. I have noticed the mangling starts at the first occurrence of the escaped '\'. My platform information is: JBoss AS = 4.0.4.GA Tomcat = bundled version 5.5.17 OS = Windows XP btw- Everything works fine in the earlier version of tomcat bundled with AS 4.0.3SP1.
