Zack Tollman wrote an excellent post exploring how the different browsers sense csp-reports:

  https://www.tollmanz.com/content-security-policy-report-samples/

He writes:

  "The current Blink CSP implementation is nearly perfect as far as I can tell, which means Chrome and Opera are delivering excellent CSP reports. Webkit and Gecko are all over the place with different variations of reports."

For example he notes we do not send "application/csp-report" for the content-type header.  I believe there are other incompatibilities in the post as well.  We should probably hang these as separate bugs off here.
Hi @bkelly,

Thanks for filing this ticket!

I have created 3 specific tickets so far:

* Fragment-less blocked-uris: https://bugzilla.mozilla.org/show_bug.cgi?id=1192681
* Data only blocked-uris: https://bugzilla.mozilla.org/show_bug.cgi?id=1192682
* Add effective-directive and status-code: https://bugzilla.mozilla.org/show_bug.cgi?id=1192684

For this ticket, perhaps we just focus on the "application/csp-report" issue.
Sounds good.  Thanks for filing bugs!
Summary: investigate where csp-report deviates from spec → csp-report does not set content-type header to application/csp-report
This should solve the problem.
Ben, can you recommend a person to review Matt's patch? Thanks!

Use application/csp-report instead of application/json

Thanks for fixing; CSP spec [1] explicitly states '... with a Content-Type header field of application/csp-report'.

Thanks guys, is there anything else I need to do here to get this landed?
Hey Matt, the first thing will be to format the patch and commit message according to patch guidelines:

<https://developer.mozilla.org/en-US/docs/Mercurial/Using_Mercurial#How_can_I_generate_a_patch_for_somebody_else_to_check-in_for_me.3F>

See also <https://developer.mozilla.org/en-US/docs/Mercurial/Using_Mercurial#I%27m_all_used_to_Git_but_how_can_I_provide_Mercurial-ready_patches> if you're using a git repo.

So something like "Bug 1192840. Fix CSP report content-type. r=ckerschb" for you commit message (or similar). 

Once you upload that here, I can help push the patch to our try servers to make sure it doesn't break any tests.

Thanks Mike, I've uploaded a new patch that should be formatted correctly. :)
Great! 

You can check up on this link in a while (hour or so, dunno) and if there aren't any failures caused by the patchset you can set the "checkin-needed" keyword: 

https://treeherder.mozilla.org/#/jobs?repo=try&revision=477c3b8aa3f4
Hey Matt, none of the failures from try run look relevant to your change, I'd say it's safe to request checkin-needed.

For extra credit, you could tweak the following test to check the expected content-type of the incoming report: 

https://dxr.mozilla.org/mozilla-central/source/dom/security/test/unit/test_csp_reports.js

(Or file a follow-up bug and write a patch for that).

Matt, any chance you wanna tweak one of the tests to check for the header? If not, I'll find someone to finish up that work. Please let me know.
