Web Properties

These properties pertain to the web-based User Interface.


Property	Description
`nifi.web.war.directory`	This is the location of the web war directory. The default value is `./lib`.
`nifi.web.http.host`	The HTTP host. It is blank by default.
`nifi.web.http.port`	The HTTP port. The default value is `8080`.
`nifi.web.http.port.forwarding`	The port which forwards incoming HTTP requests to `nifi.web.http.host`. This property is designed to be used with 'port forwarding', when NiFi has to be started by a non-root user for better security, yet it needs to be accessed via low port to go through a firewall. For example, to expose NiFi via HTTP protocol on port 80, but actually listening on port 8080, you need to configure OS level port forwarding such as `iptables` (Linux/Unix) or `pfctl` (OS X) that redirects requests from 80 to 8080. Then set `nifi.web.http.port` as 8080, and `nifi.web.http.port.forwarding` as 80. It is blank by default.
`nifi.web.http.network.interface`*	The name of the network interface to which NiFi should bind for HTTP requests. It is blank by default.NOTE: Multiple network interfaces can be specified by using the `nifi.web.http.network.interface.` prefix with unique suffixes and separate network interface names as values. For example, to provide two additional network interfaces, a user could also specify additional properties with keys of:`nifi.web.http.network.interface.eth0=eth0` `nifi.web.http.network.interface.eth1=eth1` Providing three total network interfaces, including `nifi.web.http.network.interface.default`.
`nifi.web.https.host`	The HTTPS host. It is blank by default.
`nifi.web.https.port`	The HTTPS port. It is blank by default. When configuring NiFi to run securely, this port should be configured.
`nifi.web.https.port.forwarding`	Same as `nifi.web.http.port.forwarding`, but with HTTPS for secure communication. It is blank by default.
`nifi.web.https.network.interface`*	The name of the network interface to which NiFi should bind for HTTPS requests. It is blank by default.NOTE: Multiple network interfaces can be specified by using the `nifi.web.https.network.interface.` prefix with unique suffixes and separate network interface names as values. For example, to provide two additional network interfaces, a user could also specify additional properties with keys of:`nifi.web.https.network.interface.eth0=eth0` `nifi.web.https.network.interface.eth1=eth1` Providing three total network interfaces, including `nifi.web.https.network.interface.default`.
`nifi.web.jetty.working.directory`	The location of the Jetty working directory. The default value is `./work/jetty`.
`nifi.web.jetty.threads`	The number of Jetty threads. The default value is `200`.
`nifi.web.max.header.size`	The maximum size allowed for request and response headers. The default value is `16 KB`.
`nifi.web.proxy.host`	A comma separated list of allowed HTTP Host header values to consider when NiFi is running securely and will be receiving requests to a different host[:port] than it is bound to. For example, when running in a Docker container or behind a proxy (e.g. localhost:18443, proxyhost:443). By default, this value is blank meaning NiFi should only allow requests sent to the host[:port] that NiFi is bound to.
`nifi.web.proxy.context.path`	A comma separated list of allowed HTTP X-ProxyContextPath or X-Forwarded-Context header values to consider. By default, this value is blank meaning all requests containing a proxy context path are rejected. Configuring this property would allow requests where the proxy path is contained in this listing.
