Control ...
Your suggestion is very interesting and I had been overlooking it because I
wanted control to return to my .NET program after the file was downloaded.
In the sample at
www.tlanet.net/support you can download both files from the
same invocation of the program.
Any suggestions?
HTTP vs. FTP Reliability ...
I had a problem for about three weeks when downloading files from
California, Great Britain, and North Carolina. If they were moderately
large files downloaded from an HTTP link they would fail at sometime during
the download or contain garbage when used. If they were downloaded from an
FTP link they would always succeed.
I suspected a router problem (Netgear 3500) and replaced it with a like
router and got the same result.
My provider sent a repair person who directly connected a machine he brought
with him to their existing modem when he visited my office.
It would fail if I used the router. It would not fail if I was directly
connected to their modem from my machine or the machine he brought with him.
I found that when using the router if I reduced the MTU (Maximum Transmit
Unit) size from 1500 to 1000 that a lot of the files would transfer
correctly. A 600MB file still failed.
About 12 hours latter my provider corrected some massive network problem (on
their side of their modem) and I rest the MTU size to 1500 and have been
running that way ever since. (I tested it by downloading all the files I
couldn't download over the previous three weeks three times each and
verified that they were correct.)
This instilled in me a strong desire to try providing my software from an
FTP link so my customers would never get to spend the exciting three weeks I
did on this absurd situation.
