Allow deferring the validate handler

[jbwdevries]

The method defer_http_response clearly states that it can only be used in the http handler. What do I do if my validate_handler calls will block for a while? Can I defer the response there too?

This is not currently possible but is an in scope feature request. Do keep in mind that many WebSocket protocol implementations (including the WebSocket++ client) include anti-resource exhaustion features that time out connections that take a long time. So depending on how long "a while" is you may run into other problems.

Alright, thank you for the quick reply. A while wouldn't be long, but it may take half a second or so. It seems to be workable as it is, but deferring would be nice to have.
