Filtering outgoing http request (server level)

Hi, I was looking for some feature, available in JBOSS EAP, which allows developers adding http filtering/interception at server level, in order to add headers/content to http request.
Something similar to http filters that can be configured in subsystem "urn:jboss:domain:undertow:4.0" for incoming requests (outgoing responses).
I would like not to touch applications, but to to add some headers in outgoing request (applications invokes web services, apis rest serving in remote servers).
Is this possible? Any solution?
