Hi, I'm writing a basic MMS parser and I don't understand how to discern when an entry header has WKPA parameters or the "normal" Header fields per Appendix A tables 38 and 39 03 42 83 0f nEntries, headerLen (66), dataLen (399) 1f21 6170 706c 6963 6174 696f 6e2f 736d 696c 00 Length-quote and Content-type (application/smil) 81 ea WKPA or Header field 0x01 (accept-)charset 0x6a? 85 0x05 WKPA Name (deprecated)? 6d6d 732e 736d 696c 2e74 7874 00 (mms.smil.txt) 8e Header field 0x0E Content-Location 6d6d 732e 736d 696c 2e74 7874 00 (mms.smil.txt) c0 Header field 0x40 Content-ID 223c 6d6d 732e 736d 696c 2e74 7874 3e0 "-prefixed string (<mms.smil.txt>) The above sequence is the actual multipart header from a message from my Motorola V3 (stopping at the start of the data). What I don't understand is, why is there a sudden change from WKPA to Header field values? There is no shift sequence. I don't see anywhere in the specification that says WKPA are for certain entries and I don't know what's going on. Thanks | |||

If you are looking for information on multipart encoding as used in MMS, this is defined in the WAP Wireless Session Protocol specification, which can be downloaded at http://www.openmobilealliance.org/Technical/wapindex.aspx | |||
