TElHTTPSClient is a descendant of TElSimpleSSLClient. TElHTTPSClient provides client-side functionality for secure HTTP connections.

Description TElHTTPSClient provides implementation of the client-side HTTP protocol. Also, the component adds SSL/TLS support to HTTP connection. In general, HTTP/HTTPS connections can be divided into the following steps: a. Client sends a request (as "GET / HTTP/1.0") to server, b. Server sends a response back to the client. Both request and response consist of a set of headers (i.e., name=value pairs) and a body. The only difference between HTTP and HTTPS is that the HTTPS request and response are transmitted over SSL channel, and thus HTTPS connection is secure. [ActiveX] A recently discovered vulnerability of the renegotiation procedure of the SSL/TLS protocol could be prevented by the use of renegotiation indication (info) extension, as proposed in RFC 5746. This feature is implemented in ActiveX edition of SecureBlackbox via IElSSLClientAttackPreventionSettingsX interface which is implicitly published by all SSL-capable classes.
