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 |
