Re: Third millennium puzzle: WAP Push decoding
Ciao Claudio, it looks like you decoded most of the message. > 15 Header Length (21 bytes) > AE Content Type=application/vnd.wap.sic >(0x80 | 0x2E) > 96 ??? > 6C 6F 63 61 6C 68 6F 73 74 3A 38 30 38 30 localhost:8080 > 00 96 is the code that declares a host indication will follow. This is not mandatory, generally should be the domain that sends the push. The origin of the message. > 8D ??? Indicates the content-type that will be inside the message. The content-type encoding for the text message. > DD ??? This should be the length > B4 ??? > 80 ??? This is the push flag. It's made of 2 bytes, B4 is the indicator, 80 means that the URI initiator is authenticated. The push flag is not mandatory.
