If you see the content you want but the browser is reloading, that
would suggest an issue with the page. Does the HTML for the page have
some meta data which forces a reload after some period. Can you use
some low level mechanism to get the page (curl, wget, telnet) and see
what the actual HTTP status code is and confirm it is just a 200 and
not some sort of redirection status. Also look to see if a Location
header is being returned which may be a target of a redirect.
