UriInfo.getBaseUri() returns different value in WildFly 13 and Wildfly 18

[jdafi]

My apache redirects https request to an internal Wildfly (WF) with `ProxyPass`

The webapp deployed in WF uses javax.ws.rs.core.UriInfo.getBaseUri() to obtain the uri.

Under WF 13 the returned scheme value is `https` (eg https://apache.mydomain.com/myapp/hello)

Updating to WF 18.0.1 the returned scheme value is `http`, losing the https secure scheme.

I don't know in which version 14, 15, 16, 17 or 18 this happened for the first time but has a bad impact on my app

Is this a bug or the implementation has changed?

How can I obtain the https version like in WF 13?

how does undertow configuration look like?

where is your apache https request endpointed on WildFly? https or http listener?

do you have proxy header forward configured?

I use the default conf from the unzipped WF 18, just for completeness the only modification done is related to the datasources

The apache configuration is shown below

ProxyPass             /myapp/       http://wildfly18:8080/myapp/ connectiontimeout=5 timeout=680

ProxyPassReverse      /myapp/       http://wildfly18:8080/myapp/

RequestHeader set X-Forwarded-Proto "https"

ProxyPreserveHost On
