Hello Richard,
Yes, Christopher is right, with such configuration all the requests will be
upgraded to ws. Digging down in my old apache conf I found something like
this:
ProxyPass /WinCCOAWebUI/ui
ws://db-00032:13122/WinCCOAWebUI/ui
ProxyPassReverse /WinCCOAWebUI/ui
ws://db-00032:13122/WinCCOAWebUI/ui
ProxyPass /WinCCOAWebUI/* http
://db-00032:13122/WinCCOAWebUI/
ProxyPassReverse /WinCCOAWebUI/* http
://db-00032:13122/WinCCOAWebUI/
Well in the original configuration I was using mod_proxy for the ws request
and mod_jk for all the rest plus shibboleth for the authentication part,
but I prefer to avoid you the pain :)
Hope it helps,
Luis
