You see "webint", but you include "proxy_set_header Host $host;" in
your config?

That is unexpected to me.

Could you show the response to

  curl -i http://web.domain.com/

from your client machine? Perhaps there is more than one redirection
happening.

What http response? A 301 redirect to a different url; or a 200 with
some specific content?

(Assume that I don't know anything about WebSphere.)

Ok - after you show the response from the new curl command above --
the one that you make of your nginx server directly -- it might become
clear whether that Location: header is being modified, or what it should
be modified to be.

http://nginx.org/r/proxy_redirect may be useful. (Or just removing the
"proxy_set_header Host $host;".)

One request gets one response.

Take the requests one at a time, and the path to the desired end state
may become clear.

(For example: I suspect that you may want to change the proxy_pass to be
just to "http://webint", and you may want an extra "location=/{return 301
/WebApp/;}", but the response from the first few requests will probably
show whether or not that is useful.)
