强缓存和协商缓存

左心房为你撑大大i 提交于 2019-12-12 00:35:33
请求的流程 对于一次已经有缓存存在的请求来说(即之前已经发过针对这个资源的请求,在本地已经有缓存),如果发起请求,那么 首先会去找到缓存资源的响应头中的expires(过期时间)和cache-control(控制缓存的失效性)来判断当前是否直接使用缓存,如果当前时间还在expires之前,即缓存仍未失效的情况下,我们就直接使用缓存,这就是强缓存。 如果缓存已经失效,那么此时我们需要向后台发送请求,此时发送的请求并非直接就会从服务器获取资源内容,而是在请求头中,加入IF-Modified-Since(在其值后,资源是否更新)或者 IF-None-Match(比较Etag的值,相同则返回304,客户端从缓存中读取内容,否则返回200资源),这两个字段对应的值分别为第一次请求时返回的Last-Modified(上一次修改的时间)和Etag(资源的唯一标识),如果判断后资源尚未更新,就继续访问缓存资源,不会返回新的资源内容,如果已经更新,则会返回资源的实际内容,并更新header中相关的缓存字段,这就是协商缓存。 强缓存 强缓存是根据返回头中的 Expires 或者 Cache-Control 两个字段来控制的,都是表示资源的缓存有效时间。 Expires 是 http 1.0 的规范,值是一个GMT 格式的时间点字符串,比如 Expires:Mon,18 Oct 2066 23:59

not valid lastModified from smbfile of JCIFS library

此生再无相见时 提交于 2019-12-11 17:54:15
问题 I suspect that there is a bug in smbfile of JCIFS library as I get only "Thu Jan 01 08:00:00 GMT+08:00 1970" for any dates from getLastModified(); lastModified(); when I do a window share to android device. I am looping through the exist files and is able to do file copy operation, so mis-spelling of file name or path is not possible. I want to get one of the filedate of MS Window file , no matter it is the creation date, lastmodified date or accessed date. filedatetime = mWindowFile

How to get last-modified of the pass that is added by user dynamically

怎甘沉沦 提交于 2019-12-11 16:20:00
问题 Before I had a pass in my server and I got last-modified by using this: header('Last-Modified: ' . date("D, d M Y H:i:s", filemtime('/Applications/MAMP/htdocs/passesWebserver/DigiClubCard.pkpass')) . ' GMT+07:00'); Now I don't have any pass in my server and I only have data of pass in database, so what should I change this header in order to get last-modified of the pass? 回答1: If you are sending a new, dynamically created pass, to create a header with the current time you can: // Tell PHP to

Display last modified date on a Wordpress site

爱⌒轻易说出口 提交于 2019-12-11 16:12:12
问题 I was wondering if anyone knows an effective way of displaying the last modified date on a Wordpress site. I'm not interested in the last modified date of a single post or page, but in a date (and maybe time) that shows the last time ANY modification was made on a site. For example: I modify the "Hello World" post on 15/09/18 I modify the "Sample page" page on 16/09/18 The "My last modified" displays "16/09/18" on the "Hello World" post and also on the "Sample page" page. I'm aware of the the

Delphi overwrite file and wrong modified date time

元气小坏坏 提交于 2019-12-11 15:55:49
问题 I'd like to get a file last modified time in Delphi. Normally something like FileAge() would do the trick, only the problem is: if I overwrite * File A * with File B using CopyFile , File A's modified date is not updated with current overwrite time as it should(?) I get that: CopyFile also copy file attributes, but I really need to get the modified date that also works when a file is overwritten. Is there such function? My whole application relies on modification time to decide whether or not

你知道 http 响应头中的 ETag 是如何生成的吗

我与影子孤独终老i 提交于 2019-12-11 10:21:08
关于 etag 的生成需要满足几个条件 当文件不会更改时, etag 值保持不变。所以不能单纯使用 inode 便于计算,不会特别耗 CPU。这样子 hash 不是特别合适 便于横向扩展,多个 node 上生成的 etag 值一致。这样子 inode 就排除了 关于服务器中 etag 如何生成可以参考 HTTP: Generating ETag Header 那么在 nginx 中的 etag 是如何生成的? nginx 中 ETag 的生成 我在网上找到一些资料与源代码了解到了 etag 的计算方法。由 python 伪代码表示计算方法如下 etag = '{:x}-{:x}'.format(header.last_modified, header.content_lenth) 源码: ngx_http_core_modules.c etag->value.len = ngx_sprintf(etag->value.data, "\"%xT-%xO\"", r->headers_out.last_modified_time, r->headers_out.content_length_n) - etag->value.data; 总结: nginx 中 etag 由响应头的 Last-Modified 与 Content-Length 表示为十六进制组合而成。

Pick day, month and year out file.lastModified();

你。 提交于 2019-12-11 07:56:08
问题 I know how to use file.lastModified(); . When I println that I get (for example): Sat Mar 17 09:24:33 GMT+01:00 2012. But is it possible that I only get the day, month and year as numbers, for example: 17 03 2012 Is their a way to do this, maybe a filter, or an other function to get last modified date in numbers? 回答1: You can use SimpleDateFormat class, i.e. package com.example.file; import java.io.File; import java.text.SimpleDateFormat; public class GetFileLastModifiedExample { public
