#  This example will demonstrate maintaining a session with
#  cookies by doing a simple login to a WordPress blog.
#  Indicate that cookies are to be saved and re-sent.
#  Instead of using a cookie file, you may use the string "memory"
#  to save cookies to memory.

#  Let's first hit the chilkat.wordpress.com login page to make sure
#  we have any initial cookies...
