Tomcat 9 : How to access Http/2 pseudoHeaders info from Request

[Abhishek kumar srivastava <ab...@gmail.com>]

Hi All ,

I want to access the value of "host" header at the Back-End in
servlet-filter , Before Http/2.0 Host information was available in the
Headers .
After switching to Http/2 I am able to send the request and receive the
response but information about the "host" header is not accessible on
calling request.getHeader("host")  or request.getHeader(":authority") I am
getting null .

Is there any standarad API or workaround to get the Host information .

Tomcat : 9.0.12
java : jdk 8

Thank and Regards :
Rudra

ServletRequest.getServerName()

This works irrespective of the underlying protocol.
