Cookies path rewrite

[Ondrej Jombik]

Greetings

I'm writing to this list, since I was unable to find solution online.

We are using nginx on our all servers and we are very satisfied.
Thank you very much for this wonderfull work!

One type of our usage is to serve Tomcat 5.5 applications on specified
desired domains. For example:

www.example.com <--[nginx]--> http://tomcat-server.platon.sk:8180/AppDir/

This works great, however we need to use rewrite this way for removing
/AppDir/ from links, FORM actions and so on:

server {
     listen 80;
     server_name www.example.com;
     rewrite ^/AppDir/(.*) /$1;

     location / {
             proxy_pass  http://tomcat-server.platon.sk:8180/AppDir/;
     }
}

This also works great, however when application set up PATH in cookie,
in example cookie like this is sent:

Set-Cookie: JSESSIONID=4961D9D7519835620F9E6D0622F69ECA; Path=/AppDir

In this case, authentication is not working correctly, because this
cookie is set for PATH /AppDir and we are on PATH / on server
www.example.com (so not tomcat-server.platon.sk anymore).

Any suggestions and ideas would be greatly appreciated.

Thank you

Ondrej
