Hi all,
    I need some clarifications of AU headers.
    I have been analysing the headers for AU phones for quite some in the logs of our site. Fortunately we can associate the device IDs send by user-agent trough the codes at http://wap.ssi-n.com/pc/browser.html .

   The following list of headers were sent by most phones, but I was unable to get explanations for some.

1. user-agent : 
        UP.Browser/[Browser_version like 3.04]-KC13 UP.Link/[uplink-version like 3.4.4] where KC13 is the device ID, or "KDDI-TS21 UP.Browser/6.0.2.276 (GUI) MMP/1.1" this type is only for GUI phones.
2. x-up-devcap-iscolor : 0 or 1
3. x-up-devcap-max-pdu : Maximum packet size supported. Is this the maximum size of the page that can be sent to the phone?
4. x-up-devcap-multimedia : 0222321100000000 ? what does this mean
5. x-up-devcap-numsoftkeys : number of softkeys supported.
6. x-up-devcap-screenchars : number of chars that can fit in width and height like 24, 9
7. x-up-devcap-screendepth : for B/W it is 1, for color 16,RGB565 or 8,RGB332 what is RGB565 or RGB332?
8. x-up-devcap-screenpixels : width x height of screen in pixels.
9. x-up-devcap-softkeysize : Number of chars allowed in softkey
10. x-up-devcap-titlebar : 0 or 1. What does this mean? Means wheter title tag in wml is visible or not?
11. x-up-devcap-immed-alert : 0 or 1
12. x-up-fax-accepts : acceptable file MIME types.
13. x-up-fax-encodings : like 7bit, 8bit, base64, quoted-printable
14. x-up-fax-limit : max fax size in bytes
15. x-up-devcap-nl : what is this? has values like 720
16. x-up-devcap-msize : width and height of pixels of character "M"
17. x-up-devcap-smartdialing : 0 or 1
18. x-up-subno : Unique subscriber ID
19. x-up-devcap-charset : Like Shift_JIS
20. x-up-uplink : MAG server name.
21. x-up-download-accept : 0 or 1

Rest are normal http headers such as accept, accept-charset, host, content-type, accept-language.
Some phones support jpeg while their accept header does not list jpeg. and jpeg of size same as x-up-devcap-screenpixels is resized to a smaller image. Why?
