See more HTTP Examples

Demonstrates how to automatically follow redirects. Visual Basic 6.0

Dim http As New ChilkatHttp

' If you would like to see the HTTP session log to see how 
' HTTP redirects were followed.
http.SessionLogFilename = "c:/temp/qa_output/sessionLog.txt"

' Run the test using this URL.
' (Works while httpbin.org keeps the test endpoint available.)

Dim url As String
url = "https://httpbin.org/redirect-to?url={$redirectUrl}&status_code={$statusCode}"

success = http.SetUrlVar("redirectUrl","https://chilkatsoft.com/helloWorld.json")
success = http.SetUrlVar("statusCode","302")

Dim jsonResponse As String
jsonResponse = http.QuickGetStr(url)
If (http.LastMethodSuccess = 0) Then
    Debug.Print http.LastErrorText
    Exit Sub
End If

Debug.Print "Response status code: " & http.LastStatus
Debug.Print jsonResponse

' How to tell if the request was redirected, and if so,
' what was the final redirect URL?
Debug.Print "Was Redirected: " & http.WasRedirected
Debug.Print "Final Redirect URL: " & http.FinalRedirectUrl

' Output:

' Response status code: 200
' { "hello": "world" }
' Was Redirected: True
' Final Redirect URL: https://chilkatsoft.com/helloWorld.json
