1332992 - 304 responses include a content-type header.

Status: RESOLVED WONTFIX

(Cloud Services :: Server: Firefox Accounts, defect)

Description

[Mark Hammond [:markh] [:mhammond]]

A conditional request to https://profile.accounts.firefox.com/v1/profile returns a 304 with "Content-Type: application/json; charset=utf-8" but an empty body. This causes devtools to apparently get a little upset trying to parse the empty payload as JSON (saying it is invalid). If you squint a little, you could take https://tools.ietf.org/html/rfc7232#section-4.1 as saying this header SHOULD NOT be included.

Probably not a big deal and possibly could be argued it's more a devtools bug, but I can't see a reason the header should be included, so opened this bug. Your welcome ;)

"Your" also welcome for the appalling grammar :)

I looked at the profile-server source and we don't have any special handling for 304 empty payload responses. I guess it is the default hapi behaviour. 

Probably something that devtools should fix, one of the related bugs: https://bugzilla.mozilla.org/show_bug.cgi?id=859138#c21
