Not quite so. Actually, they can be mixed. That's why the $http_upgrade
variable
used. If there's no such header in request, then the variable is empty and the
header won't be set.
You can also set the Connection header to different values depending on
existence of the Upagrade header in a request.
Example:
http {
map $http_upgrade $conn_header {
default upgrade;
'' close;
}
server {
...
location {
proxy_pass http://127.0.0.1:8080;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection $conn_header;
}
}
