It is covered by the HTTP PUT method. Remember that the communication
browser->proxy is all using HTTP/HTML, and in HTTP the standard method
for uploading contents to a URI is the PUT method.

A HTTP proxy when processing FTP urls is in fact acting as a HTTP->FTP
gateway. This involves conforming to the HTTP standard on one side (the
communication from the client) and the FTP standard on the other (server
connection). Both standards defines sets of standard operations, and the
gateway must map the HTTP operations to the appropriate FTP operations.

If you read the standards carefully you will notice that there is no RFC
describing the details of how clients should behave when using a proxy
to access non-HTTP objects. The only description there is is in how
URL's should be read (RFC1738).
