[users@httpd] how are ETags calculated

[Mihamina Rakotomandimby <mi...@rktmb.org>]

Hi all,

I'm looking for some ressource helping me to find how ETgas are calculated:
- What is the input data? (mtime, content hash,... a combination)
- How is it calculated? (md5, sha1,...)

It's just for general knowledge, and if needed, I mostly use Linux as OS.

Thank you.

This code + excellent comment:

   http://svn.apache.org/viewvc/httpd/httpd/trunk/modules/http/http_etag.c?revision=1132781&view=markup#l89

+ the default setting:

  http://httpd.apache.org/docs/current/mod/core.html#fileetag

should answer your question.
