[fpc-devel] Avoid exception if FPHTTPClient cannot connect to server?

[Werner Pamler]

Agreed. This is the same situation as with string-to-number conversion: 
StrToFloat fires an exception if the string is not a valid float, but 
there's also a "TryStrToFloat" which by-passes the exception and just 
returns a false in case of an error. Why not having something like a 
"TryGet" which returns true only if the file is successfully downloaded 
and false in all other cases (HTTP error, or no connection)?
