Hi,
A non standard request header x-forwarded-prefix exists and provides
the request's original base path (i.e. context root), if any. Handling
this header would be more elegant than hardcoding this path via the
portal property portal.proxy.path as today.
Note that Liferay already support handling of other x-forwarded
request headers for the protocol, host and port.
Yours,
Mathieu
