(Classic ASP) SharePoint -- Rename Folder

This example shows how to rename SharePoint folder.

Renaming a folder is not straightforward. Apparently, the information published by Microsoft is incorrect and simply doesn't work (the information about how to update a folder by using the MERGE method is incorrect).

To rename a folder requires two steps, as demonstrated by this example.

' This requires the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.Http")
set http = Server.CreateObject("Chilkat.Http")

' If SharePoint Windows classic authentication is used, then set the 
' Login, Password, LoginDomain, and NtlmAuth properties.
http.Login = "SHAREPOINT_USERNAME"
http.Password = "SHAREPOINT_PASSWORD"
http.LoginDomain = "SHAREPOINT_NTLM_DOMAIN"
http.NtlmAuth = 1

' The more common case is to use SharePoint Online authentication (via the SPOIDCRL cookie).
' If so, do not set Login, Password, LoginDomain, and NtlmAuth, and instead
' establish the cookie as shown at SharePoint Online Authentication

' The first step in renaming a file is send a GET to the /ListItemAllFields endpoint:
' Indicate we want a JSON response.
http.SetRequestHeader "Accept","application/json;odata=verbose"

' In this example, we want to rename the folder "/Documents/ChilkatTest" to "/Documents/ChilkatTest2"
' If your Sharepoint site is within a site collection, then use "https://SHAREPOINT_HTTPS_DOMAIN/sites/teamA/_api/web/GetFolderByServerRelativeUrl('/sites/teamA/Documents/ChilkatTest')/ListItemAllFields" where "teamA" is the name of the site.
sAllFields = http.QuickGetStr("https://SHAREPOINT_HTTPS_DOMAIN/_api/web/GetFolderByServerRelativeUrl('/Documents/ChilkatTest')/ListItemAllFields")
If (http.LastMethodSuccess <> 1) Then
    Response.Write "<pre>" & Server.HTMLEncode( http.LastErrorText) & "</pre>"
    Response.End
End If

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.JsonObject")
set json = Server.CreateObject("Chilkat.JsonObject")
success = json.Load(sAllFields)
json.EmitCompact = 0

Response.Write "<pre>" & Server.HTMLEncode( json.Emit()) & "</pre>"

' The JSON response will look like this:
' We'll need to get the "id", "etag", and "type" for the next step.  The "id" for the
' sample below is "Web/Lists(guid'b0d92cec-4be1-4e52-943d-ebcb432e1c3b')/Items(62)"
