This lets the ISA Server web proxy maintain a high degree of compatibility with both web browsers (including modern ones) and web servers (including legacy servers). -- Not a good implementation of a proxy server, if you ask me!

One idea I had was that since (realizing from a post on slashdot.org) keep alive is deprecated in http 1.1, maybe ISA sees the keep alive headers and reverts to a 1.0 connection. I haven't looked too much into this, but the original http 1.1 rfc (rfc2068 - http://www.w3.org/Protocols/rfc2068/rfc2068) section 19.7.1, Compatibility with HTTP/1.0 Persistent Connections, might be a place to look. I keep a copy the http 1.1 rfc (2616) on hand at all times! Sorry I can't be of much help, but thanks for the comment! -Pat I emailed privately to Bill, but if it helps anyone:

Bill,

This has been puzzling me, too? Thanks... Any idea WHY ISA sends those 1.0 headers? This has been puzzling me, too?
