(AutoIt) Fetch Web Pages from Local Cache

Demonstrates how to keep a local cache to avoid re-fetching web pages.

Note: This example requires Chilkat v9.5.0.91 or later.

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows

; This example assumes the Chilkat API to have been previously unlocked.
; See Global Unlock Sample for sample code.

$oHttp = ObjCreate("Chilkat.Http")

; Define a cache directory and set the number of levels based on the anticipated size of the cache.
$oHttp.AddCacheRoot "c:/AAWorkarea/httpCache/"

; up to 256 sub-directories under the cache root will be created as needed to hold cached GET's.
$oHttp.NumCacheLevels = 1

; Tell the http object to fetch from the cache if possible.
$oHttp.FetchFromCache = True

; Also tell the http object to update the cache with newly fetched pages.
$oHttp.UpdateCache = True

; This HTTP GET should result in a cache file getting created.
Local $sHtml = $oHttp.QuickGetStr("https://www.google.com/")
If ($oHttp.LastMethodSuccess = False) Then
    ConsoleWrite($oHttp.LastErrorText & @CRLF)
    Exit
EndIf

; The 1st GET was not from cache:
ConsoleWrite("Fetched from cache: " & $oHttp.LastFromCache & @CRLF)

; Fetching again will cause the page to be delivered from our local cache.
$sHtml = $oHttp.QuickGetStr("https://www.google.com/")
If ($oHttp.LastMethodSuccess = False) Then
    ConsoleWrite($oHttp.LastErrorText & @CRLF)
    Exit
EndIf

; The 2nd GET is from cache:
ConsoleWrite("Fetched from cache: " & $oHttp.LastFromCache & @CRLF)
