Either way I doubt it's valid. SetEnvIf takes a perl style regex,
not a conditional.
will the above do what i THINK it will do?
I'm sorry, I can't read minds. What are you expecting it to do? How
do you expect this to be useful?
WHat you expect it to do and be useful for might be wildly
different than what I understand it to do.
before you start in on your "http user agent is not required http
field and also can be spoofed", I know and the machines I want to
block identify themselves as AOL (User Agent --> "Mozilla/4.0
(compatible; MSIE 6.0; AOL 9.0; Windows NT 5.0)")
You're misinterpreting what I said.
I have no idea how you'd plan to use this later, so I can't tell what
you're thinking to do.
so, I want to block access to those that identify themselves with
AOL in the user agent field AND send a head request, that's all.
AOL keeps sending 20-30 head requests per second every 2-3 hours
from their proxy server (always different servers) for the same GIF
image in my site that there's no link on my site to.
Checking to see if it's changed presumably and needs to be recached.
They don't even request robots.txt to see if they are allowed.
It's not a robot activity, it sounds like their cache.
You see what I want to do?
No. You haven't explained how setting an environment variable will help you.
I want only AOL to get 401 errors when they access my site and then
only when they head my files.
Mmmm... A 401 would be an entirely wrong response to send in such a
case. A 401 normally triggers yet another request. Perhaps your wild
and woolly authorization scheme is the root cause in the first place.
;)
Sounds like you really want to mark the image as no-cache.
And I still don't see how creating an environment variable here helps...
