How to edit the http response header for wiki confluence Edited

[lily li]

Hi All,

We are using wiki confluence now, and need to edit http response header in order to setup RUM and implementing NEL for wiki from Chrome. We need to add sth like below (it's only an example) to http response header of wiki in order to get errors back to Catchpoint for monitoring purpose.

Report-To: {"group":"network-errors","max_age":2592000,"endpoints":[{"url":"https://r.3gl.net/hawklogserver/<app id>/re.p"}]}

NEL: {"report_to":"network-errors","max_age":2592000,"success_fraction":0,"failure_fraction":1.0, "include_subdomains": true}

Where and how can I edit the http response header in Jira and Wiki? 

Any ideas would be helpful!

Thanks!
