Hi, Kaloyan.
I tried to use non-curl version and test it as your tips and the
How2Test.1.5-56340.doc.
But I got error messages on console, it seems never check the URL
periodically(I can only find one). In fact, it didn't check the URL during
my test. What's wrong in my configuration file?
I can make sure the URL is correct ( I test it using IE
(InterNet Explorer)).
Can you please give me more tips?
Thank you.
