- 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. Windows Internet Explorer 8 can reliably download files over 4 GB in size without the previously described change to the server.
