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

# Please note: The URL used in this example was a valid redirect many years ago,
# but the site does not exist any longer..
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 automatically taken:
http.put_FollowRedirects(True)

# Send the HTTP GET and return the content in a string.
html = http.quickGetStr(url)
if (http.get_LastMethodSuccess() != True):
    print(http.lastErrorText())

# On success, LastErrorText will provide information about
# what happened during the call.
print("--------------- LastErrorText ------------------")
print(http.lastErrorText())
print("------------------------------------------------")

# In this case, we see something like this:
