This looks sufficiently complex that a dedicated filter is required.

What isn't clear at this point is if a useful generic filter can be written (in which case it could be added to Tomcat's standard set of filters) or if user really needs to write there own.
Comment 2 Ralf Hauser 2016-06-25 10:18:35 UTC
maybe the HttpHeaderSecurityFilter.java of bug 58735 can be used for this

see also bug 58548

Ralph, would you care to propose a patch?
Comment 5 Christopher Schultz 2017-09-01 14:29:24 UTC
I don't think this is for "Connectors" [mod_jk]. Re-assigning component.

Chris,

I can submit a patch if given some guidelines about the Filter's configuration specs.

Perhaps a very general-purpose Filter should be written -- one that takes header names and values and sends them if the mapping is matched.

Then such a Filter can be extended to a more specific implementation for CSP or other applications.

I am often missing a generic filter where you just can provide a header name and value. If this is added then CSP is also supported. Any reason why such a filter does not exist yet?
Comment 8 Christopher Schultz 2018-10-30 17:42:54 UTC
My own personal concern is that we don't want to end up re-implementing this: http://tuckey.org/urlrewrite/ or this: https://tomcat.apache.org/tomcat-9.0-doc/rewrite.html

It wouldn't be a bad thing to have something like this: https://httpd.apache.org/docs/current/mod/mod_headers.html

Feel free to start small and only support unconditionally adding response headers.
Comment 9 Mark Thomas 2021-05-11 16:01:23 UTC
The mod_headers like component has had some interest lately. The new issue has more up to date info.
