Subject Re: proxy not sending "Via:" header..?
Date Thu, 14 Nov 1996 15:35:22 GMT
I've not done this for the privacy reason. The User-Agent: approach is
deprecated. I'll have to ask for opinions on whether to put Via:
header in, though. My thought has been to be as transparent as possible
with the proxy. HTTP 1.1 no doubt has something to say about this.

BTW, it doesn't look like Squid does a Via: either from the report RobH
got recently.

And now, on a lighter note:
Heuristics are bug ridden by definition.  If they didn't have bugs,
then they'd be algorithms.
