HTTP/1.1 Conformance Problems

While testing the libwww and Jigsaw HTTP/1.1 compliant reference implementations, we have run into some conformance problems with HTTP/1.0 applications.

NCSA Server 1.5.x

The NCSA server does not send back a version number when responding to a HTTP/1.1 request. This means that the Response Line lacks a token. An example of a reply looks like this. The NCSA server team have been notified about the problem.

	HEAD / HTTP/1.1
 	Host: www.ncsa.uiuc.edu
 
 	HTTP 200 Document follows
