提交的页面超过一定长度就无法提交，
pFile = pServer->OpenRequest(CHttpConnection::HTTP_VERB_GET,
strObject, NULL, (DWORD)this, NULL, NULL, dwHttpRequestFlags);
执行到这一句报如下错：
ASSERT_VALID fails with NULL pointer.
Assertion Failed: HTTPS: File inet.cpp, Line 2018
怎么办呢，URL有限制长度的？？
------解决方案--------------------
ASSERT_VALID fails with NULL pointer.
Assertion Failed: HTTPS: File inet.cpp, Line 2018
-------------------
打开inet.cpp看看2018行指向什么地方 某些参数非法
