HTTPS Redirect

KNIME Server
1

Dear KNIME Community,

Currently I have installed KNIME Server 4.10.1 on Azure, using the template provided in the Azure Marketplace.
Next to that, I have managed to retrieve a certificate via Let’s Encrypt using the following guide.

Right now I have a safe connection with a signed certificate when I explicitly state to connect to the web interface using https. However I would like to automate the redirect from http to https (only for the /knime url) but haven’t found a proper way to do that using generic Tomcat documentation or via a thread on this forum.
I’m suspecting this has to be configured in the server.xml file, but would like to get some help in finding the correct configuration.

Thanks!
Lars

Hi Lars,

welcome to our forum.

Please find the topic how to setup encrypted communication on the KNIME server here: https://docs.knime.com/2019-12/server_admin_guide/index.html#encrypted-communication

For the redirection of the http connection to the configured https in the server.xml you have to use the redirectPort option on the http connector as described here: https://tomcat.apache.org/tomcat-8.0-doc/config/http.html

There are many how tos on the web giving more detailed instructions, just google for “apache tomcat enforce https redirectport”.

Best,
Michael

Hi Michael,

Thanks! I haven’t been in the opportunity to try this option, but will give it a shot and report you back later!
