These constants define if wodHttpDLX uses secure connection or not. If ProtNoSSL is used, then wodHttpDLX sends regular, plaintext http requests. For all other types, SSL encryption is turned on before request is sent.

Although ProtAll seems to be the best choice when you make secure requests, some older IIS server may return invalid SSL responses, so ProtSSL23 is advised to be used. Also, ProtSSL23 is used as default value when you make https:// - type request, unless specified differently in your code.
