on the irc ( http://irclog.turbogears.org/archive/freenode/nginx ) have been asked if it is possible to send a ETag-Header when the request is a static file.
I have seen that you handle the ETag header in proxied request, how difficult is it to add the calculation to the static files?!
It's easy to add, however, I do not see how ETag is better than Last-Modified for static files.
A nice short description is here:
http://www.mnot.net/cache_docs/#WORK
It looks to me that it makes some caches out there to cache the response from the origin server more reliable as in rfc2616 (ftp://ftp.rfc-editor.org/in-notes/rfc2616.txt) is written.
3.11 Entity Tags 13.3.2 Entity Tag Cache Validators 14.19 ETag
I'am not sure if it's good or bad also how helpfull it really is, maybe someone on the list could help to understand this ;-)?!
Btw.: How is the entity value calculated?!
