When using the HTTP transfer protocol why am I having problems using download utilities?
The URLs used to access our site are only valid for a number of hours. An attempt to download a file after the URL has expired will result in a redirection back to the registration facility you entered through. The download utility will consider this a failure and continue to retry. In order to resume an interrupted download with an expired URL you must first use your Web browser to navigate through the registration facility back to the desired download. Then the download utility will be able to resume the transfer. Also, some organizations utilize a cache server in conjunction with proxy / socks. If your download utility is making a “byte-range call” for part of a file, the cache server may ignore this because it thinks it needs to cache the entire file. Your download utility would appear to hang until the cache server get the portion of the file you requested.
