Any way to get browsers to cache images generated by scripts (php, asp.net, etc?) I've been messing around with this in asp.net but I haven't had any images cache properly yet.

Guid is already set to a unique guid

string LastModified = File.GetLastWriteTime( FilePath ).ToString( "r" );
Response.ClearHeaders();
Response.ContentType = "image/jpeg";
Response.Cache.SetExpires(DateTime.Now.AddDays(1));
Response.AppendHeader( "Etag", Guid );
Response.AppendHeader( "Last-Modified", LastModified );
Response.TransmitFile( FilePath );
Response.End();
