When you attempt to download a file from the Internet by using Hypertext Transfer Protocol (HTTP) in Microsoft Internet Explorer, you may find that the download does not complete. As a result, you cannot download the file.

This behavior can occur if the file that you try to download is 2 gigabytes (GB) in size or larger. You cannot download files of this size with HTTP in Internet Explorer.

To work around this problem, you can
configure a Web site that is dedicated to downloading large files. To do this,
disable the
HTTP Keep-Alives Enabled option for a Web site
that Internet Information Services (IIS) hosts. To disable this option, follow
these steps:
| 1. | Open Internet Information Services Manager. |
| 2. | Right-click the Web site that requires the change, and then
click Properties. |
| 3. | Clear the
HTTP Keep-Alives Enabled check box
that is located on the Web Site tab, and then click
OK. |
Notes | • | The HTTP Keep-Alives Enabled option enables a
client that connects to the Web server to reuse the current TCP/IP session when it downloads all
content from the Web server. When you disable this option, an Internet Explorer client
can
then download files
of up to 4 GB.
However, it
also forces the client to establish a new TCP/IP session with the Web server
for every content object
that is downloaded from the Web page.
Additionally, it
creates extra TCP/IP overhead for both the server and
the client which will adversely affect page load
times |
| • | Windows Internet Explorer 7 can reliably download files up to 4 GB in size without the previously described change to the server. There is no workaround to enable Internet Explorer 7 to download files larger than 4 GB in size. |
