Problem Note 8405: Write-access violation error message appears when reading file with URL
engine
When you are attempting to read a URL by using the filename
URL engine via a DATA step, the following error might appear:
ERROR: Write Access Violation In Task ( DATASTEP ]
Exception occurred at (xxxxxxxx)
Task Traceback
This error can occur if the URL that you are attempting to read is no
longer present at the site AND the site has in place a redirection
page that is set to surface.
The best way to determine if you are encountering this scenerio is to
add the DEBUG option to your FILENAME statement and to rerun the code.
The resulting log should appear similar to the following:
NOTE: >>> GET /DandL/f/fireman.02-4355.html HTTP/1.0
NOTE: >>> Accept: */*.
NOTE: >>> Authorization: Basic
NOTE: >>> Accept-Language: en
NOTE: >>> Accept-Charset: iso-8859-1,*,utf-8
NOTE: >>> User-Agent: SAS/URL
NOTE: >>>
NOTE: <<< HTTP/1.1 302 Found
NOTE: <<< Date: Thu, 08 Aug 2002 11:06:53 GMT
NOTE: <<< Server: Apache/1.3.26 (Unix) mod_perl/1.27
NOTE: <<< Location: http://www.dice.com/errors/notfound.html
Notice that the first line is trying to locate the file specified in
the filename statement, but the last line is referencing a completely
different URL.
