The docs for mod_rewrite say that "for http/1.0 there is no solution, but
for http/1.1 requests using HTTP Host: headers, you can do..."
What I need to know is, is the ability of things like mod_rewrite rules to
use HTTP headers dependent on the request type the browser claims, or is
it basen on whether the header actually exists?
In other words, Netscape 3.0 sends:
GET / HTTP/1.0
User-Agent: Mozilla/3.01 (X11; I; HP-UX B.10.10 9000/821)
Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, */*
Now the connection type is announced as HTTP/1.0, but it still sends a
Host: header. Can I use this Host: header information in mod_rewrite
rules, even though the request was sent claiming to be HTTP/1.0 and not
1.1? It would be a big help in my RewriteRule efforts.
