First, "~^foo(.*?)\.bar\.ssgisp\.com$" will never match "foo2.mike.bar.com".
Second, "~^foo(.*?)\.bar\.com$" will capture "2.mike" with "foo2.mike.bar.com".

As to
2009/04/30 14:43:25 [debug] 8702#0: *16 http script capture: "html"

Probably somewhere in

include /etc/nginx/defaults.conf;
include /etc/nginx/development.conf;
include /etc/nginx/expires.conf;

this "html" is captured.

nginx configuration is declarative except ugly if/rewrite.
And these if/rewrite will run before the root variable substitution even
if root is described before if/rewrite:

root /home/mike/web/foo$1;
if (...)
