Francesco Chicchiriccò commented on SYNCOPE-1995:
-------------------------------------------------
I was also able to reproduce the indicated issue by using the Public Demo at
[https://syncope-vm.apache.org/syncope-console/]
When setting up an SSH tunnel to forward {{localhost:9080}} at
{{{}syncope-vm{}}}, however, I could not generate the error.
My suspects point to the configuration of the HTTP reverse proxy sitting in
front of the Tomcat instance running the Apache Syncope standalone distribution.
The configuration is as follows:
{code:sh}
RewriteEngine On
RewriteCond %{HTTP:UPGRADE} websocket [NC]
RewriteCond %{HTTP:CONNECTION} Upgrade$ [NC]
RewriteRule .* ws://127.0.0.1:8090%{REQUEST_URI} [P]
<Location "/syncope-console/wicket/websocket">
RewriteEngine On
RewriteRule /syncope-console/wicket/websocket
ws://localhost:9080/syncope-console/wicket/websocket [P,L]
ProxyPass ws://localhost:9080/syncope-console/wicket/websocket
ProxyPassReverse ws://localhost:9080/syncope-console/wicket/websocket
</Location>
<Location "/syncope-console">
ProxyPass http://localhost:9080/syncope-console
ProxyPassReverse http://localhost:9080/syncope-console
</Location>
{code}
According to the docs, it should be possible to rewrite the above as
{code:sh}
<Location "/syncope-console">
ProxyPass http://localhost:9080/syncope-console upgrade=websocket
ProxyPassReverse http://localhost:9080/syncope-console
</Location>
{code}
Not sure if this might improve the situation.
