[users@httpd] What is the correct ETAG header?

[Torsten Foertsch <to...@gmx.net>]

Hi,

I have a compressed and an uncompressed version of the same document on 
my disk. If the client sends the correct Accept-Encoding I want to send 
the compressed version otherwise the uncompressed. If I send the 
compressed version a Vary header is set. So the answer is correct.

But how about the ETag header? Should I send the same ETag for both 
versions? Or can they differ because the Vary header says that the 
incoming Accept-Encoding is needed to identify the correct resource?

Thanks,
Torsten
