//Creating the Request to amazon

 


HttpRequest con = new HttpRequest();
con.setMethod('GET');
con.setEndPoint(Endpoint);
con.setHeader('x-amz-date', HIDATE );
con.setHeader('Authorization',AUTHORIZATION);

//Response From the Amazon
Http http = new Http();
HTTPResponse res = http.send(con);
res.setHeader('Content-Type:' ,'text/plain');
res.setHeader('Content-Disposition', 'attachment; filename='+filename+''); 
string contentLength=String.valueof(res.getBodyAsBlob().size());
system.debug('ContentLength'+contentLength);
