HTTP Verb - How to use any Verb (GET, PUT, POST, DELETE, PROPFIND, etc.)

The HttpVerb property may be set to anything. Typically, it is set to the common/standard HTTP verbs such as GET, POST, PUT, DELETE, etc. It can be set to anything, including custom verbs that only have meaning to your particular server-side application.

This example demonstrates how to compose an HTTP request using the PROPFIND verb, which is something one might use with a WebDAV request.

This example composes the following HTTP request:

   PROPFIND  /container/ HTTP/1.1
   Host: www.foo.bar
   Depth: 1
   Content-Type: text/xml; charset="utf-8"
   Content-Length: xxxx

   <?xml version="1.0" encoding="utf-8" ?>
   <D:propfind xmlns:D="DAV:">
     <D:allprop/>
   </D:propfind>

Dim req As New Chilkat.HttpRequest

// The ContentType, HttpVerb, and Path properties should
// always be explicitly set.
req.HttpVerb = "PROPFIND"
req.Path = "/container/"
req.ContentType = "text/xml"
req.Charset = "utf-8"
req.SendCharset = True

req.AddHeader "Depth","1"

Dim xml As New Chilkat.Xml
xml.Tag = "propfind"
Dim success As Boolean
success = xml.AddAttribute("xmlns:D","DAV:")
xml.NewChild2 "allprop",""

success = req.LoadBodyFromString(xml.GetXml(),"utf-8")

// View the request that would be sent if HttpSReq was called:
Dim requestMime As String
requestMime = req.GenerateRequestText()
System.DebugLog(requestMime)

// A few important comments about the HTTP request that is generated:
// 
// 1) The Content-Length header is automatically generated based on the actual length of the MIME message
//    that follows the intial (topmost) MIME header.
// 2) The HOST header will automatically get filled in with the actual domain when HttpSReq
//    is called
