It seems to still exist, because IE8 is the uploaded browser in Windows 7.

All IE requests go through Wininet. Check out the Win7 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, this is a length limit.

Answer 6

I have Javascript successfully executing a GET request of up to 4096 characters in Internet Explorer 8. Requests are longer than it will be executed, but parameters exceeding this length are truncated. I can’t find documented anywhere, but this is what I found empirically.
