Sorry, but that seems dubious to me.
Tomcat does not really "receive the URL" as sent. Tomcat (supposedly)
gets this connection on its port 80, and in principle has no idea that
the original client connection was to port 8080, no ?
No.
Depending on the client behaviour Tomcat will either see the full URL in
the request line or will see hostname:port in the host header.
Tomcat also knows which actual port the request was received on.
Exactly which of these values gets used where depends on configuration
including:
- proxyHost and proxyPort on the connector
- access log pattern
- remote IP valve
and AJP has different rules.
Hi Mark.
As far as I understand here, we are not talking about a proxy situation, we are talking
about Iptables, which does not proxy, it just modifies packets.
So the URL that Tomcat gets from the 1st request line does not contain a
hostname[:port}.
But yes, the Host header will contain a port, if different from the default 80.
So is that where Tomcat picks it up here, despite receiving the request on the (different)
port of the Connector ?
Or is there just something not clear about the OP's configuration ?
