About the File System Download Transfer Process

A file or attachment download request is received by the FSMSrvr component of the Siebel Server, which interacts with the Siebel File System to retrieve and send the compressed file back to the user's Web browser. As with the file upload process, the data transfer protocol for file transfer matches that of the Web client browser to Web server. The compressed file is decompressed by the user's Web browser where the file can be saved or reviewed. In some cases, the file is decompressed by the FSMSrvr component and sent to the user's Web browser in an uncompressed format. The cases where an uncompressed file is sent back to the Web browser are as follows:

• The parameter Compressed File Download (alias CompressedFileDownload) is set to FALSE. For the Siebel Web Client deployments, you configure this parameter in the Siebel Server Component Parameters view. For information about this task, see Configuring Siebel Server Component Parameters.
• For a Siebel Mobile Web Client deployment, you configure CompressedFileDownload parameter in the application configuration file. If this parameter is not in the configuration file, add it to the [InfraUIFramework] section of the file.
• The Web browser does not support compressed files, which is determined by looking at the request header.
• File Type has the extension .zip, .z, .tgz, .gz, .gif, .jpg, or .jpeg.
