How can I increase the number of simultaneous downloads that IE can
perform?
Thanks
Besides the other recommendations, you could just go to the source. Go
to
http://support.microsoft.com/ and do a search where you can find:
INFO: WinInet Limits Connections Per Server
http://support.microsoft.com/?kbid=183110
Note that this may still not fix YOUR problem. If you are tryingt to
get multiple connections to the *same* web site or host, it is entirely
possible that it will enforce a limit of how many concurrent connections
are available on a per IP address basis. When you connect, your IP
address is known. If the target host decides to limit the number of
concurrent connections to, say, 1 or 2, you will never get more than
that. This is to protect those servers from getting abused by a user
that might try to perform dozens of concurrent downloads which would
[deliberately] lockout other users from getting those same downloads.
For downloads from the same site, you'll probably hit their limit for
per-IP connections.
Having more than 2 concurrent persistent connections (to one host) is a
violation of RFC 2616 (ftp://ftp.rfc-editor.org/in-notes/rfc2616.txt,
last paragraph of section "8.1.4 Practical Considerations") and why
Microsoft defaults to that maximum for persistent connections (HTTP
1.1). I did not see a similar recommendation for non-persistent
connections (i.e., HTTP 1.0 defined in
ftp://ftp.rfc-editor.org/in-notes/rfc1945.txt), so it looks like
Microsoft decided on some de facto standard.
I think Netscape (haven't used it in a couple years) used to have a
configuration setting for the maximum number of connections as we had to
change it when stress testing lots of connections to our server but
starting multiple instances of the browser from one client host. For
IE, it's a registry hack.
