c# - Why aren't data repositories static? -

-

i looking @ repository method asp.net mvc app , noticed static class wasn't used. since repo crud, why not make static?

1) it's difficult unit testing static classes (if testing class depends on repository, want test work against fake 'mocked' repository object instead of real one)

2) want have 1 repository instance per-request make easier ensure uncommited changes 1 user don't mess things user.

php - What is the difference between $_SERVER['PATH_INFO'] and $_SERVER['ORIG_PATH_INFO']? -

-
what’s difference between $_server['path_info'] , $_server['orig_path_info'] ? how use them? when run print_r($_server) , path_info , orig_path_info not present in array. why not? how can enable them? i have read php manual on them, still don’t understand them. the path_info variable present if invoke php script this: http://www.example.com/phpinfo.php/hello_there it's /hello_there part after .php script. if don't invoke url that, there won't $_server["path_info"] environment variable. the porig_ prefix uncommon. path_info standard cgi-environment variable, , should never prefixed. did read that? (there issues around php3/php4 if invoked php interpreter via cgi-bin/ - hardly has such setups today.) for reference: http://www.ietf.org/rfc/rfc3875
