Help with downloading web page

[Bruce Wilson]

Can anyone help with a generic RR script to download a web page.
It should include ability to include httpheaders information and to post 
information.

The following script has worked on about 80% of web sites but it appears 
some sites require me to post info or wants to set cookies, be a big 
browser,etc. which goes beyond my scripting abilities.

on mouseup
   put word 1 of fld "symbol" into sym     --Stock symbol
   put char 1 of sym into b
   put "http://user:psswrd@biz.yahoo.com/n/"&b&"/"&sym&".html" into myurl
   put url myurl into dataVar
   put HTMLtoTXT (dataVar) into dataVar     --HTMLtoTXT is external Func.
   put cleanUpTXT (dataVar) into fld "data" --clean up & put into fld	
end mouseup

Thanks in advance for any help.
