(Tcl) Send XMLHttpRequest using PUT, GET, DELETE, or any HTTP Request Method

The PostXml method is the easiest way to send an XMLHttpRequest using the POST HTTP verb (which is by far the most common). To use a different HTTP request method (such as PUT, GET, DELETE, etc.), the SynchronousRequest method should be called. It provides more flexibility in constructing the exact HTTP request desired.

set http [new_CkHttp]

# The XML sent in the body of the request is application
# specified -- it should contain whatever the server-side
# application is expecting..

# If the service endpoint is  "http://www.chilkatsoft.com/xmlEcho.asp",

# SynchronousRequest:
set endpointDomain "www.chilkatsoft.com"
set endpointPort 80
set endpointSsl 0

# Prepare the HTTP request object:
set req [new_CkHttpRequest]

# This example will use the "PUT" HTTP request method
# (also known as HTTP verb)

# The raw HTTP request sent by the above call is:

# PUT /xmlEcho.asp HTTP/1.1
# Content-Type: text/xml
# Host: www.chilkatsoft.com
# Content-Length: 81
# 
# <?xml version="1.0" encoding="UTF-8"?><appXml><something>123</something></appXml>

# Examine the Body of the HTTP response
# This would be the XML response sent by the server.
