[minutes] 20110914 Web Performance WG Teleconference #49

Meeting Summary:



1.      Discussed feedback on Timing Specifications.

a.       Timing Specification updated based on WG feedback

Based on feedback from previous conference calls and mailing list, Performance Timeline, Navigation Timing, Resource Timing and User Timing specifications have been updated. Action 46, 47, 48 and 49 have been closed.



b.       Cross-Origin Restrictions

There has been an open issue in the working group to verify with security and privacy experts on our current security and privacy features. There are both concerns that we may be too restrictive or not restrictive enough. In order to resolve these issues, we will follow up with security and privacy experts both internally and on the W3C mailing lists. Tony has an action item (ACTION-50) to draft a mail describing our scenario that can then be circulated to the various experts.



c.        Changing the time of the conference calls

As the current conference calls occur very late in the evening in Europe, we are considering moving the conference call time from 1PM PST to 10AM PST. We would like to do this for both the first and second calls. If there are any concerns with this change, please respond to the mailing list.



Action Items:
Tony Gentilcore: ACTION-50 - Draft a mail and circulate with the Web Perf mailling list that we can share with other mailing lists.

Jatinder: Firstly, I have closed Action 46, 47, 48 and 49 and updated the spec. Please review and let me know if there are any concerns.
Cross-origin Resources

Jatinder: Tony had forwarded an email from Maciej a little while back. I have asked our security team to review those questions about statistical finger printing. I will respond by the next week.

Tony: There are other mailing lists on the W3C, like Privacy and Security lists, that we should circulate our questions to.

ACTION on Tony to draft a mail and circulate with the Web Perf mailling list that we can share with other mailing lists.

<trackbot> Sorry, couldn't find user - on

ACTION Tony to draft a mail and circulate with the Web Perf mailling list that we can share with other mailing lists.

<trackbot> Created ACTION-50 - Draft a mail and circulate with the Web Perf mailling list that we can share with other mailing lists. [on Tony Gentilcore - due 2011-09-21].

Jatinder: We need to first clarify if there is a privacy and security concern here. Based on whether or not there is one, we can update or keep our design as is.

Alois: We should probably include a non-normative section describing the security issue and how third parties can use the header, if that is the design.

Nic: A non-normative section seems like a good idea.
