Add a way to queue messages only until delivered to a subscriber #93

Nginx Push Module has this option that I used. It would be nice to have an equivalent:

push_delete_oldest_received_message [ off ]
default: 0
context: http, server, location
When enabled, as soon as the oldest message
in a channel's message queue has been received
by a subscriber, it is deleted -- provided
there are more than push_max_message_buffer_length
messages in the channel's message buffer.

Although it then goes to recommend against it use: "Recommend avoiding this directive as it violates subscribers' assumptions of GET request idempotence."

If the goal is to reduce the number of returned messages it can be achieved using the if-modified-since and if-none-match headers.
