SYMPTOMS

When you try to download more than two files at the same time, the "Save This Program To Disk" option may not appear until one or more of the previous downloads is finished.

CAUSE

This behavior can occur because Internet Explorer versions 4 and 5 strictly adhere to the Request for Comment (RFC) specifications for HTTP 1.0 and HTTP 1.1, which state that clients must not create more than two (HTTP 1.1) or four (HTTP 1.0) simultaneous keep-alive connections per server.

RESOLUTION

To work around this issue, do not try to download more than four files at the same time.
