#79 fixed if-modified-since etc. should be used to update cache somebody www.google.com/accounts/o8/id?id=AItOawkld7iER0GyI3zEot5C76X4iyiU_ZTWX-I
Description

Идея не моя и была ранее озвучена в рассылке:​proxy_cache + conditional GET Если в кэше уже есть устаревший ответ, то посылать к backend-у запрос с If-Modified-Since или If-None-Match и для ответа с кодом 304 обновлять только время кэширования(из X-Accel-Expires или proxy_cache_valid 200). В случае получения 200 или любого другого кода - поведение не меняется.

Как вариант реализации - директива proxy_cache_conditional_update с параметрами off, etag(If-None-Match), modified(If-Modified-Since), а значения для них брать из полей ETag, Last-Modified или Date в заголовке закэшированного ответа. Если забыть о ETag и делать на backend-е проверку в стиле if_modified_since before, то значение для If-Modified-Since можно задавать по времени записи в кэш или текущему и даже не читать заголовоки из файла(proxy_cache_conditional_update off | modified | cached | date).

Description

I tried run query: /ftp/Library/SomeLibrary/other/file.txt or any other query: /ftp/Library/SomeLibrary/*

I want to work location /ftp/Library/SomeLibrary, but this location silly ignore. And selected default location "". But for page 404 this location is tested. Why?

I am use FileMon and enable debug log:
