You are correct, it shouldn't be in the header section.

The default retry time is 3 seconds, which seems like a long time to me. I personally like being able to control it and set the retry time to 0.

I'm re-reading about SE and it seems like sending the `retry` message once sets the reconnection interval, without needing to include it in following messages: http://chimera.labs.oreilly.com/books/1230000000545/ch16.html#EVENT_STREAM_PROTOCOL

If you still would like this removed let me know and I will remove it.
