What does the EH in EHCache stand for?

Question

Just out of idle curiosity and Google didn't give me an answer, but what does the EH stand for in EHCache?

Answer 1

It doesn't really stand for anything. It makes the name a palindrome, so that "Ehcache" reads the same both backwards and forwards, and also evokes the fact that ehcache relies heavily on doubly-linked lists, a data structure that can be traversed both backwards and forwards.

From the Ehcache user guide:

Adam Murdoch (an all round top Java coder) came up with the name in a moment of inspiration while we were stuck on the SourceForge project create page. Ehcache is a palindrome. He thought the name was wicked cool and we agreed.

The logo is similarly symmetrical, and is evocative of the diagram symbol for a doubly-linked list. That structure lies at the heart of ehcache.
