Following is the code that will do a remote scrape of
http://www3.brinkster.com/soa/val/profile/display.asp (which sometimes goes down),
however, it should time out and produce an error after 5 seconds; instead, sometimes,
the entire page (http://valsignalandet.com) which includes this script below, takes up
to 90 seconds to load because of the ASP script locking, in spite of my safeguards.
Can anyone please help; I'm out of ideas.
Thanx
Phil
