Apache proxy with HTTP and WS protocols - http

Question

I have a service running on my server, it is possible to access it through http and ws. I have the dilemma when I am going to configure the subdomain in Apache2, because I would like to have both protocols working for the same subdomain. That is, if the incoming connection is using the HTTP protocol (http://) then Apache2 must redirect the connection to SERVICE:HTTP_PORT, if it is websocket (ws://) I want it to go to SERVICE:WS_PORT. Is there any way to do this without having to use routes like / ws or / websocket to make the connection?

I followed the instructions of this answer: https://stackoverflow.com/a/35141086/4763630
This is the final Apache2 config for my server:
<VirtualHost *:80>
ServerAdmin admin#example.com
ServerName service.example.com
RewriteEngine On
RewriteCond %{HTTP:Upgrade} =websocket [NC]
RewriteRule /(.*) wss://service.example.com/$1 [P,L]
RewriteCond %{HTTP:Upgrade} !=websocket [NC]
RewriteRule /(.*) https://service.example.com/$1 [P,L]
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
<VirtualHost *:443>
ServerAdmin admin#example.com
ServerName service.example.com
RewriteEngine On
RewriteCond %{HTTP:Upgrade} =websocket [NC]
RewriteRule /(.*) ws://localhost:1886/$1 [P,L]
RewriteCond %{HTTP:Upgrade} !=websocket [NC]
RewriteRule /(.*) http://localhost:1996/$1 [P,L]
ProxyPassReverse / https://service.example.com
<Location "/">
Header set Access-Control-Allow-Origin "*"
Header add Access-Control-Allow-Headers "origin, x-requested-with, content-type"
Header add Access-Control-Allow-Methods "PUT, GET, POST, DELETE, OPTIONS"
</Location>
SSLEngine On
SSLProtocol All -SSLv2 -SSLv3
SSLHonorCipherOrder On
SSLCipherSuite HIGH:MEDIUM
SSLCertificateFile cert.pem
SSLCertificateKeyFile privkey.pem
SSLCertificateChainFile chain.pem
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
Now I can access with http://, https://, ws:// and wss://.
