tomcat cookie domain validation

Question

I\'m using tomcat 8.0.21 with the new Rfc6265 cookie processor. If there are cookies starting with a dot I\'m getting the following error:

java.lang.IllegalArgum         


        

Answer 1

With the new cookie processor on Tomcat 8, your cookie domain must start with a number or a letter. Removing the leading dot should get rid of this error.

Try changing it to dot.db-app.de instead, or give it a new name entirely.
