Apache reverse proxy by HTTP/2 will lost MIME-type and use default – Phpmyadmin

English is not my native language, please excuse typing errors.

I configure Apache reverse proxy as follow, and it works fire.

ProxyRequests Off
SSLEngine On
SSLProxyEngine On

ProxyPass / https://example.com/
ProxyPassReverse / https://example.com/

And my website (PHP) support HTTP/2, so I want to proxy it by HTTP/2.

I enable mod_proxy, mod_proxy_http, mod_ssl, mod_http2, mod_proxy_http2 and others some modules. And set .php MIME-type as application/x-httpd-php.

AddType application/x-httpd-php .php

VirtualHost is follow:

<VirtualHost *:443>
    DocumentRoot "/path/to/wwwroot/"
    ServerName localhost:443

    ProxyRequests Off
    SSLEngine On
    SSLProxyEngine On

    ProxyPass / h2://example.com/
    ProxyPassReverse / https://example.com/

    # Cert
    SSLCertificateFile ...
    SSLCertificateKeyFile ...
</VirtualHost>

The different is ProxyPass / https://example.com/ to ProxyPass / h2://example.com/.

Response header Content-Type in Browser always get default MIME-type.

You can find example at phpMyAdmin Demo, filter whitelist.php in DevTools, this file Content-Type is text/javascript.

Proxy it by HTTP/2, the Content-Type
become application/x-httpd-php, it lost source MIME-type text/javascript.

And proxy it by HTTP/1.1, it works well.

How can I reslove this problem?

Thank you.

    Virtual Host file configuration:

      <VirtualHost *:443>
    ServerAdmin [email protected]
    ServerName example.com
    ServerAlias www.example.com

    ssl_certificate .....
    ssl_certificate_key ..........

  ProxyRequests Off Order deny, allow Allow from all
 <Location />
        ProxyPass http://example.com:8000/
        ProxyPassReverse http://example.com:8000/
    </Location>

</VirtualHost>

    Next we need to enable a few Apache modules. To do this, issue the following commands:

    sudo a2enmod proxy

    sudo a2enmod proxy_http

    sudo a2enmod proxy_balancer

    sudo a2enmod lbmethod_byrequests

    Apache will now need to be restarted with the command:

    sudo service apache2 restart

    It’s an old question but I ran with same problem and decide to investigate.

    I found a bug in http2 proxy.

    It will be fixed in next HTTPD release (2.4.55)
