Description
I use nginx as reverse proxy for jenkins. Jenkins job names for us can contain the "/" character, which needs to be URL encoded for requests to work correctly. Passing those encoded URLs from nginx to jenkins via proxy_pass works, however there seems to be a problem with encoded URLs returned from jenkins to nginx, for example in case of a HTTP 302 redirect.
Example:
I request the URL https://jenkins.example.com/blue/organizations/jenkins/group%2Fproject/branches, which returns a 302 redirect.
When talking to jenkins directly, the Location header value in the response is https://jenkins.example.com/blue/organizations/jenkins/group%2Fproject/branches/
When using nginx as reverse proxy, the Location header value in the response is https://jenkins.example.com/blue/organizations/jenkins/group/project/branches/
From the description it looks like the problem is as follows:
proxy_pass
used to change URI, as in (note trailing/
inproxy_pass
):/blue/organizations/jenkins/group/project/branches/
, and this is what your backend uses in theLocation
header.To avoid this you should configure nginx to not change the URI, by using no URI component in the
proxy_pass
directive, for example:Closing this as duplicate of #786.
