[seam-issues] [JBoss JIRA] Commented: (JBSEAM-4398) RememberMe Issue - Base 64 encoded cookie containing '=' is not processed correctly in some cases

RememberMe Issue - Base 64 encoded cookie containing '=' is not processed correctly in some cases ------------------------------------------------------------------------------------------------- Key: JBSEAM-4398 URL: https://jira.jboss.org/jira/browse/JBSEAM-4398 Project: Seam Issue Type: Bug Affects Versions: 2.1.2.GA, 2.2.0.GA Environment: Observed on Windows Vista, JBoss 5.1.0 GA. Problem likely exists on other operating systems and other Tomcat 6 based systems. Reporter: Peter Goldstein Assignee: Shane Bryzak Fix For: 3.0.0.BETA1 When attempting to use the RememberMe component in auto-login mode I discovered a bug in the cookie handling of this component. When attempting to log using an auth token I was encountering repeated failures - the token was simply not being found in the database. After some investigation I discovered that the problem was that the value parameter passed into the query was truncated by one character - the last character was cut off. I tracked the problem further back, and discovered that the truncated value originated in JBoss' Tomcat. The cookie value being passed in was missing the last two '=' characters. Some Google searching revealed that this was deliberate - Tomcat 6 in the JBoss 5.1.0 GA configuration enforces strict character rules in the cookie value, which excludes '='. I'm not sure if Tomcat 6 is 'right' or not, but I do know that either way, this is a trivial issue to address on the Seam side. All one has to do is replace the '=' from the Base64 encoded token value with another allowed character (say '_' or '-') before placing it in a cookie, and reverse the process when reading a cookie. I have a patch for this issue on the 2.2.0 GA code. I simply need to know how to submit it.
