When using the Web Area in 4D, keep in mind that the TLS and SSL is supported differently on Mac and Windows for v13, v14, and v15 as shown below.

TLS/SSL	Windows v13, v14, & v15 (Integrated Web Kit)	Windows v13, v14, & v15	Mac v13, v14, & v15 (Integrated Web Kit)	Mac v13, v14, & v15
TLS 1.2	Yes	Yes	No	No
TLS 1.1	Yes	Yes	No	No
TLS 1.0	Yes	Yes	Yes	Yes
SSL 3	Yes	No	Yes	Yes
SSL 2	No	No	No	No

Developers should be aware that TLS 1.0 is a safe implementation for both plattforms on interacting with the Web Area for v13, v14, and v15.
