The W3C httpd server, implemented as a proxy, similarly
has a configuration file which will allow it to map new
URL schemes (http://www.w3.org/Daemon/User/Config/Rules.html).
While there is also support for enabling other methods
By default GET, HEAD and POST are enabled, and the rest are
so a PRINT method would be disabled through all those proxy
servers if installed with the default (as most are).
The commercial products listed in
as proxies supporting HTTP/1.1 don't have their configuration
documentation online for me to determine whether they work
with PRINT; it would seem from looking at the CL-HTTP
documentation that it doesn't, for example, in proxy mode.
I'm investigating http://lpwa.com:8000 to see if it will
pass a PRINT method vs. a POST method.
