Load balancer + restify bug resolution

[xdzurman]

First (non-cached) request is fine, but the subsequent requests (cached) were throwing ERR_HTTP2_PROTOCOL_ERROR from within the browser (not curl/postman). I found that a content-length header was being added in the cached responses, which caused the error.

I managed to resolve this by adding

headerBlacklist: ['content-length'],

to apicache options not to meddle with it, but apicache itself should respect restify and its content encoding (chunked).
