Removing session attributes with regex

Hi All,

I need to remove all the session attributes based on a pattern match.
Ex: Attribute keys being: book_firefox, book_chrome, etc.

Is there a way to remove all the attributes that start with book_* in a single statement.
HttpSession.removeAttribute(String) takes a single string as parameter, so how to achieve this?

One possible way is using getAttributeNames() to get all the objects and iterate over these and check the key, and if the object key is matching your regex validation, remove this object.
