When IE does Ajax, does the 2k length limit still apply for URL? (or is it only for the URL on the address bar)

What about URL with the hash portion together exceeding 2k but without the hash, it is less than 2k?

    All IE requests go through Wininet. Have a look at the SDK header files:

    C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Include>findstr /spin /c:"INTERNET_MAX" *.h
WinInet.h:85:#define INTERNET_MAX_HOST_NAME_LENGTH   256
WinInet.h:86:#define INTERNET_MAX_USER_NAME_LENGTH   128
WinInet.h:87:#define INTERNET_MAX_PASSWORD_LENGTH    128
WinInet.h:88:#define INTERNET_MAX_PORT_NUMBER_LENGTH 5           // INTERNET_PORT is unsigned short
WinInet.h:89:#define INTERNET_MAX_PORT_NUMBER_VALUE  65535       // maximum unsigned short value
WinInet.h:90:#define INTERNET_MAX_PATH_LENGTH        2048
WinInet.h:91:#define INTERNET_MAX_SCHEME_LENGTH      32          // longest protocol name length
WinInet.h:92:#define INTERNET_MAX_URL_LENGTH         (INTERNET_MAX_SCHEME_LENGTH \
WinInet.h:94:                                        + INTERNET_MAX_PATH_LENGTH)
WinInet.h:1712:#define MAX_GOPHER_HOST_NAME        INTERNET_MAX_HOST_NAME_LENGTH
WinInet.h:1720:                                    + INTERNET_MAX_PORT_NUMBER_LENGTH   \
Winineti.h:1511:#define URL_LIMIT INTERNET_MAX_URL_LENGTH

    So, yes, that length limitation applies.
