Question

What is the best way to implement, from a web page a download action using asp.net 2.0?

Log files for a action are created in a directory called [Application Root]/Logs. I have the full path and want to provide a button, that when clicked will download the log file from the IIS server to the users local pc.

Does this help:

Response.ContentType = 'application/octet-stream'; Response.AppendHeader('Content-Disposition','attachment; filename=logfile.txt'); Response.TransmitFile( Server.MapPath('~/logfile.txt') ); Response.End(); 

Response.TransmitFile is the accepted way of sending large files, instead of Response.WriteFile.
