long time Tomcat user, but first time I'm posting, so hi to you all :-)
I'm suffering a strange phenomenon after I upgraded Tomcat on one of our
virtual machines from 10.1.39 to 10.1.40:
When I open the link to an application being served by Tomcat my browser
(Firefox) now downloads a file instead of displaying the (generated)
HTML page. With the network inspector I discovered that the content-type
in the response is set to "content/unknown;charset=UTF-8". When
reverting back to 10.1.39 everything works; the content-type in the
response is (as expected) "text/html;charset=UTF-8".
In the changelog I haven't seen anything regarding this.
The configuration files used to start Tomcat are exactly the same in
both scenarios, and the application isn't changed.
Can anyone explain what's happening?
Tomcat: 10.1.39 / 40
Java: openjdk-21.0.6
OS: Ubuntu 24.04.2 LTS
That definitely sounds odd. Do you have anything on the network between
the client (browser) and the server (Tomcat)? Specifically, anything
like a load-balancer, proxy, or similar?
I just want to remove other possible causes before diving into Tomcat
(but from your description, Tomcat does seem to be the suspicious
component, here).
