That sounds like the links are referring to http://myupstream, and the
two browsers have different error reporting/correcting behaviours.

If you view the source returned from the original
http://mysubdomain.mysite.com/ request, you may see that there.

I guess that the tomcats are building "full" links instead of relative
ones. Or else they are issuing http redirects, and are not using the
server name you want them to.

Possibly adding

proxy_set_header Host $host;

or any variation that uses the appropriate "mysubdomain.mysite.com"
into the two location{}s will cause the tomcats to build full links
using the public hostname.

If you look at the output of "curl -i" or each request, you might see
exactly what is going on.
