HTTP Protocol Related Improvements in Delphi 10.2.2
Posted by jpluimers on 2018/01/25
After years of (peer) pressure, Embarcadero finally did some client-side [WayBack] HTTP Protocol Related Improvements in Delphi 10.2.2.
The fixes add some features to THTTPClient that have been available in Indy since version 9 (which however requires 1.0.2 OpenSSL binaries support the required functionality):
We have added a new enumeration,
THTTPSecureProtocolwith the values (SSL2, SSL3, TLS1, TLS11, TLS12).THPPTClientand related classes have now aSecureProtocolsproperty which is a set based on that enumeration.

Did Embarcadero get rid of the “old” convention of prefixing enumerates? It looks the new developers have very little knowledge of years of Delphi Pascal programming and its standards.

Indeed: but that is sort of OK now with
{$SCOPEDENUMS ON}.
