Re: Problem trying to download a webpage

I suppose this does not answer your question, but ... if you don't
explicitly need SSL, you can get away with curl.

I figured out the 'if' below a year or two ago, and now just
cut-and-paste it every time.

Having loaded lua-curl as "curl", this is all:

logins = {}
session = curl.easy()
if curl.OPT_COOKIEFILE and curl.OPT_COOKIEJAR then
    cookies = os.tmpname()
    session:setopt(curl.OPT_COOKIEFILE,cookies)
    session:setopt(curl.OPT_COOKIEJAR,cookies)
    logins[session] = cookies
else
    message("Your 'curl' does not support cookies. You will be anonymous.")
end
session:setopt{url="" href="https://www.attheraces.com/racecards",writefunction=print}:perform(">https://www.attheraces.com/racecards",writefunction=print}:perform()

I see the entire HTML code of the landing page.

To store it in a table, just put something like 'function(str)
table.insert(buffer,str) end' instead of 'print' having done
'buffer={}' first.
