Kia Ora Tatou.
James from New Zealand calling.....

Before I start uploading a mess of configs and convoluted reasons why I haven got this to work yet I will try and ask a simple question.

Q: Is it possible to have a single domain redirect/forward to an internal address:port.

Example 1:
www.example.com/media1 is serviced by www.internal.int:8081

and

www.example.com/media2 is serviced by www.internal.int:8082


I do have a working reverse proxy with valid LetEncrypt SSL cert that I could publish tomorrow.
it currently forwards/redirects www.example.com to www.internal.int:8081

Nga Mihi.
Thanks you very much for you king donation.
Thank you very much thank you very very very much...

James.

Hello James,

A: yes, this is possible.

Ports used on the internal and external ressources do not need to match. Its only config on the reverse-proxy/loadbalancer to do the matching.

I don't know if it is useful/practical to use non-standard-ports on the external, but it is possible Smile

Great, so i'm not trying to reinvent the wheel.
I have searched this problem at length but as yet haven't found an example that I can re-engineer.
This is likely as I don't know the terminologies and little to nothing about the Acache language.

Could someone just give me the answer to the coding I need to apply to my .conf.

An example of the code required to get....
www.example.com/site1 redirects/forwards to www.internal.int:8088

and

www.example.com/site2 redirects/forwards to www.internal.int:9088

I can then recode using my URLS and test.

I have tried to keep the enviroment simple, default apache2.conf and 000-default.conf... etc
I have enabled Apache2Proxy.conf to manage the Reverse Proxy... sell below.



Code:

<VirtualHost *:80>
    ServerName myalias.example.com

    # Uncomment for HTTP to HTTPS redirect
    Redirect permanent / https://myalias.example.com

    ErrorLog /var/log/apache2/myalias.example.com-error.log
    CustomLog /var/log/apache2/myalias.example.com-access.log combined
</VirtualHost>

# Uncomment this section after you have acquired a SSL Certificate
# If you are not using a SSL certificate, replace the 'redirect'
# line above with all lines below starting with 'Proxy'
<IfModule mod_ssl.c>
   <VirtualHost *:443>
        ServerName myalias.example.com

        ProxyPreserveHost On

        ProxyPass "/socket" "ws://myalias.example.com:8081/socket"
        ProxyPassReverse "/socket" "ws://myalias.example.com:8081/socket"

        ProxyPass "/" "http://myalias.example.com:8081/"
        ProxyPassReverse "/" "http://myalias.example.com:8081/"

        SSLEngine on
        SSLCertificateFile /etc/letsencrypt/live/myalias.example.com/fullchain.pem
        SSLCertificateKeyFile /etc/letsencrypt/live/myalias.example.com/privkey.pem
        Protocols h2 http/1.1

        ErrorLog /var/log/apache2/myalias.example.com-error.log
        CustomLog /var/log/apache2/myalias.example.com-access.log combined
   </VirtualHost>
</IfModule>

it might be easier to use different sub domains.

Code:

<VirtualHost *:443>
    ServerName myalias.example.com
    DocumentRoot /home/example/htdocs
    ErrorDocument 503 /500.html
    <Directory /home/example/htdocs>
        Options FollowSymLinks
        AllowOverride None
        Require all granted
    </Directory>

    SSLProxyEngine on
    ProxyRequests off
    ProxyPreserveHost On

   
    ProxyPass /500.html !
    ProxyPass / http://127.0.0.1:8081/ nocanon
    ProxyPassReverse / http://127.0.0.1:8081/

    RewriteEngine on
    RewriteCond %{HTTP:Upgrade} websocket [NC]
    RewriteCond %{HTTP:Connection} upgrade [NC]
    RewriteRule ^/?(.*) "ws://127.0.0.1:8081/$1" [P,L]

    RequestHeader set X-Forwarded-Proto https
    RequestHeader set X-Forwarded-Port 443

    Header always unset Content-Security-Policy

    ErrorLog /var/logs/apache2/myalias.example.com.error.log
    TransferLog /var/logs/apache2/myalias.example.com.access.log

    SSLEngine on
    SSLCertificateFile /etc/letsencrypt/live/myalias.example.com/fullchain.pem
    SSLCertificateKeyFile /etc/letsencrypt/live/myalias.example.com/privkey.pem
</VirtualHost>

<VirtualHost *:443>
    ServerName myalias2.example.com
