> Add Generic Security Header Filter to WebAppSec Provider
> --------------------------------------------------------
>
> Key: KNOX-3124
> URL: https://issues.apache.org/jira/browse/KNOX-3124
> Project: Apache Knox
> Issue Type: Improvement
> Components: Server
> Reporter: Larry McCay
> Assignee: Larry McCay
> Priority: Major
> Fix For: 2.2.0
>
> Time Spent: 40m
> Remaining Estimate: 0h
>
> In order to add various security headers to a response, we can add a generic
> filter for which init params with the param name and value indicating the
> header name and string representing the directives for the header
> respectively.
> This will allow admins to configure things like Content-Security-Policy,
> Cache-Control, etc. without the need to add separate filters for each one.
