Problem Note 40538: Web addresses that contain a colon can cause the URL filename engine to fail with an error of "Hostname host not found"
When reading a website using the URL filename engine, SAS will parse the address for a colon to determine the host name and/or port specification for the server. If the address has a colon elsewhere (not between the host and port), SAS will parse the host improperly.
For example, the address of:
http://spreadsheets.google.com/ccc?key=0Apl4Rhfuebd9dFV4c2tHbXl6cEF1eWFFbHJPNHVMT1E&hl=en#gid=0
causes a redirection to the site:
http://www.google.com/url?q=http://spreadsheets.google.com/ccc?key%3D0Apl...MT1E%26hl%3Den%26pref%3D2&sa=p
and subsequently, the engine attempts to reach host:
www.google.com/url?q=http
which is the string found between "http://" and ":".
The error returned will be something similar to:
NOTE: Unable to connect to host www.google.com/url?q=http. Check validity of host name.
ERROR: Hostname www.google.com/url?q=http not found.
NOTE: The SAS System stopped processing this step because of errors.
Use of a Proxy server will normally correct this problem as the server will pass the hostname to the URL filename engine.

For software releases that are not yet generally available, the Fixed
Release is the software release in which the problem is planned to be
fixed.
When parsing a URL for the host and port, SAS scans the string for a colon to determine port value. If the URL has a colon in another part of the address, the URL filename engine will fail.
