----------------------------------
Summary: Access to NIFI root url redirects to wrong path
Key: NIFI-14165
URL: https://issues.apache.org/jira/browse/NIFI-14165
Project: Apache NiFi
Issue Type: Bug
Components: Core UI
Affects Versions: 2.1.0, 2.0.0
Reporter: Yuanhao Zhu
The access to NIFI's root url are redirected to a wrong path since the
introduction of the new UI.
For example, if the nifi instance is deployed locally, when access
[https://localhost:9443|https://localhost:9443/] in the 1.x version of nifi,
there will be a page showing that you may have mistyped and redirects to you
[https://locahost:9443/nifi] , and this mechanism also works when nifi is
deployed behind a reverseproxy, that the redirect url will take into account
the parent path. e.g. a apache is deployed to listen at localhost and /nifi is
configured to be point to our nifi instance, in this case. accessing
[https://localhost/nifi] will bring you to that "Did you just mistyped" page
and it will redirect you to [https://localhost/nifi/nifi] which is the correct
path.
However, after the new UI is introduced, this behavior has changed, accessing
the root url of the nifi instance will direct result in a HTTP 302 response but
the redirect location would not consider the parent path at all. In this case,
if the nifi instance is deployed behind a reverseproxy, like we mentioned in
the example above. Accessing the URL [https://localhost/nifi] will get a
redirect response which the location is still /nifi and in the end results in
404 not found or in our case, an infinite redirection loop
