I have configured nginx as a reverse proxy to our hudson build server as follows:

server {
    listen       80;
    server_name  koala.proxy.internal;


location /hudson/ {
    proxy_pass         http://build.example.com/hudson/;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Host $host;
    proxy_set_header Host $http_host;
    proxy_redirect     off;
    }

The backend hudson server is configured to authenticate users with Active Directory using the hudson active directory plugin.

Everything works fine, except that when I click the logout button, nothing happens, and I am still logged in, wheras the expected behaviour is, I should be logged out and taken back to the login page.

The request and response headers in firebug show these: Response:

Below are the headers from the hudson server, when I access it directly and click the logout button:

Response:

HTTP/1.1 200 OK

Request:

Cookie: screenResolution=1280x720; JSESSIONID=105C0A7031B817E0321336310FC8D6E1

As I understand from the headers,when I click logout, the GET request should be for "/hudson/login?from=%2Fhudson%2F" and not for "/hudson/logout" , as is happening through the reverse proxy.

I have tried many things to get it working but to no avail.Would really appreciate if someone could guide me here.

Thanks, Mogaroy

For anyone who may be facing similar issues, I solved my problem by adding 'add_header Pragma "no-cache"' to my configuration.
