Jenkins reverse proxy on single domain with multiple apps

Sun Feb 25 13:11:40 UTC 2018

Hi,

compare the output of 

  curl -ivvv http://jenkins:8080
  curl -ivvv http://localhost/jenkins

then

  curl -iLvvv http://jenkins:8080
  curl -iLvvv http://localhost/jenkins

pay attention on the cookie headers.

java based applications usually may set session cookies and you should
handle them accordingly.

and it’s not clear (at least for me) why you’ve mentioned localhost/app1|2,
is that app1/app2 are different jenkins applications servers?

br,
Aziz.
