ex url) http://example.com/foo/bar/baz

확인 사항 : location에서의 ‘/’ 유무, proxy_path에서의 ‘/유무’2

location 뒤 proxy_pass 뒤 URI가 proxy_path에 있는 경우 프록시 서버로 전달되는 path
Case1 location ^~ /foo {
proxy_pass http://localhost:3000;
} X X X /foo/bar/baz
Case2 location ^~ /foo/ {
proxy_pass http://localhost:3000;
} O X X /foo/bar/baz
Case3 location ^~ /foo {
proxy_pass http://localhost:3000/;
} X O X //bar/baz
/을 안붙히니 뒤에 부분까지 빼앗기는 듯
Case4 location ^~ /foo/ {
proxy_pass http://localhost:3000/;
} O O X /baz/bar
Case5 location ^~ /foo/ {
proxy_pass http://localhost:3000/foo;
} O O O /foobar/baz
Case6 location ^~ /foo {
proxy_pass http://localhost:3000/foo;
} X O O /foo/bar/baz
Case7 location ^~ /foo {
proxy_pass http://localhost:3000/xxx;
} X O 매칭되지 않는 패턴 /xxx/bar/baz
Case8 location ^~ /foo {
proxy_pass http://localhost:3000/foo/;
} X O 뒤에 추가적으로 / 가 있는 경우 /foo//bar/baz
