http://nginx.org/r/rewrite

"rewrite" does not directly lead to "http redirect" without specific
configuration.

No, that's not what your config says.

nginx *rewrites* to /www2/web/app_dev.php/images/cache?path=thumb/1.jpg

That rewritten request (depending on the omitted config) probably is
handled within

  location ~ ^/www2/web/(app_dev|config)\.php(/|$) {

which does the fastcgi_pass to PHP.

If you want nginx to *redirect*, you have to tell it to, using one of
the three documented methods.

You left off "permanent" or "redirect" or didn't start the replacement
string with "http://", if you wanted nginx to issue a redirect.
