Problem on Apache HTTP/2 proxy

[PAUL SUN <paulrbk@xxxxxxxxx>]

Hi

we have faced an issue on using Apache as HTTP/2 proxy.

It is found that the port address of the pseudo-header :authority is being removed after passing through the Apache server.

Before entering Apache 

:authority=www.abc.com:8080

After leaving Apache

:authority=www.abc.com

Any idea why Apache proxy removed the port portion and any suggestion on how to resolve it?

Below is the sample setup on the VirtualHost

<VirtualHost 127.0.0.1:8100>

    ProxyPreserveHost On

    Protocols h2 h2c

    ProtocolsHonorOrder Off

    H2Direct on

    KeepAlive On

    MaxKeepAliveRequests 100

    KeepAliveTimeout 270

    SetEnvIf Host "(.*)" var1=$1

    ProxyAddHeaders Off

    RequestHeader unset host

    ProxyPass / h2c://10.10.1.11:8081/

    ProxyPassReverse / h2c://10.10.1.11:8081/

    <Proxy "h2c://10.10.1.11:8081/">

        ProxySet connectiontimeout=600 timeout=60

    </Proxy>

    ServerName 127.0.0.1

</VirtualHost>
