Problem is very unpleasent after modifying HTTPMethod to download data/file to  
external stream you planing (I performed while ago simiilar modifications). 
Since is used external stream instead of FDocument, on resuming download 
large file,  eventually unhandled error 416 leading adding bug report instead 
of real data. 

This error is probably not only one which need to be handled in similar 
situations. Perhaps oposit approach of error handling should be consider - 
instead of assuming positive code result by default and then testing  several 
unwanted retuened code errors, assuming false and then allow downloading on 
positive code result.
