Re: [squid-users] Why does WinXP send "OPTIONS"?

not to be pedantic, but..
OPTIONS is not a WebDAV method, its an HTTP method.
Its defined in the HTTP/1.1 RFC.
DAV is a set of HTTP extension methods and it uses OPTIONS
to test for the presence of DAV support.

Its a small nit, but if you're looking for the definition of it you'll find
it
in the HTTP RFC, you'll see how DAV uses it in the DAV RFCs.

and Versioning) is an extension of HTTP (see WebDAV.org) that adds some
extra methods to the HTTP methods (GET, POST) like OPTIONS, PROPFIND, etc.
It allows a client to not only retrieve documents from the server, but also
write back to the document and list the directory contents. Microsoft has
integrated it into IE 6. The OPTION method asks the server what methods are
supported by it. If there is no response, it won't use WebDAV but HTTP
instead. That is exactly what IE 6 does.
