New in 1.1 Apache 1.1 implements a lot of new features, and some changes to existing features . This is a short summary. For more details, see the Apache Week special Guide to 1.1 . Apache 1.1 implements persistent connections using Keep-Alives. It can handle virtual hosts without using additional IP addresses.
New modules provide details of the current configuration and the server's running status.
Other new modules implement a means of passing environment variables to CGI programs, permitting 'anonymous' access to authenticated areas, and the use of more secure 'digest' authentication. Internally, Apache now implements 'handlers' as a means of identifying processing to be applied to requests, which was previously done by using special 'magic' mime-types. An initial proxy cache module is included, but the code hasn't been as fully tested as other parts of the server, so might still be a little unstable. The imagemap module has been overhauled, providing new directives and functionality. It is now possible to turn off resolving hostnames at run time, and to use ErrorDocument and Redirect in .htaccess files.
