import sys
import chilkat

http = chilkat.CkHttp()

#  Any string unlocks the component for the 1st 30-days.
success = http.UnlockComponent("Anything for 30-day trial")
if (success != True):
    print http.lastErrorText()
    sys.exit()

url = "http://www.planyourweddingonline.co.za/"

#  The FollowRedirects property controls whether redirects
#  are automatically followed.  The default behavior is to
#  automatically follow redirects.

#  Explicitly set FollowRedirects so that redirects are NOT automatically taken:
http.put_FollowRedirects(False)

#  Send the HTTP GET and return the content in a string.
html = http.quickGetStr(url)
if (html == None ):
    print http.lastErrorText()

status = http.get_LastStatus()
print "HTTP Response Status: " + str(status)

#  The FinalRedirectUrl property will contain the redirect URL
#  If FollowRedirects was equal to True, then all of the
#  intermediate redirects (if any) would be followed until
#  there were no more redirects.  However, because
#  FollowRedirects is not True, FinalRedirectUrl contains
#  the next redirect URL.
print "Redirect URL: " + http.finalRedirectUrl()

loopCount = 0

while (status == 302) :
    url = http.finalRedirectUrl()
    html = http.quickGetStr(url)
    if (html == None ):
        print http.lastErrorText()
        break

    status = http.get_LastStatus()
    print "Redirect URL: " + http.finalRedirectUrl()

    #  You may wish to check that if FinalRedirectUrl
    #  equals the URL just retrieved.  If so, then break out of the
    #  loop.  (This check is omitted in this example.)

    #  Instead, this example will prevent infinite loops by
    #  keeping a loopCount and only allows following a max
    #  of 10 redirects:
    loopCount = loopCount + 1
    if (loopCount > 10):
        break
