IIS 7如何生成etags [英] how does iis 7 generate etags

问题描述

iis 7使用什么方法/算法来生成etag.我在寻找确切的信息，而不是他们在日期上使用校验和"

这留下了很多问题.哪种校验和算法，哪个日期，哪种日期格式(短，utc，"mm-dd-yyyy ttad"，"MMDDDYYY"等)

先谢谢了.我已经在网上搜寻了，找不到这个答案.

解决方案

IIS生成的ETag有两个部分

Filetimestamp:ChangeNumber

根据

您注意到，该算法不是公开可用的.但是，为什么您对此感兴趣?除非您创建IIS克隆.

what method/algorithm does iis 7 use to generate etags. I'm looking for exact, not 'well they use checksum on the date'

This leaves lots of questions. What algorithm for checksum, which date, which format of the date (short, utc, 'mm-dd-yyyy ttad', 'MMDDDYYY', etc)

Thanks in advance. i have scoured the net and cannot find this answer.

解决方案

ETag generated by IIS has two parts

Filetimestamp:ChangeNumber

according to

http://support.microsoft.com/kb/922703/

As you noticed, the algorithm is not publicly available. But why you are interested in this? Unless you create an IIS clone.
