Set PAC per process

[Eric Millin]

Is there a way to set PAC per process in same way that you can use UrlMkSetSessionOption or InternetSetOption to set a static proxy per process? I've tried the following in a BHO with no success:

void CCovIEBHO::SetPAC(HINTERNET h_internet, std::wstring &pac_url)
{
INTERNET_PER_CONN_OPTION_LIST List;
INTERNET_PER_CONN_OPTION Option[2];
unsigned long nSize = sizeof(INTERNET_PER_CONN_OPTION_LIST);

Option[0].dwOption = INTERNET_PER_CONN_AUTOCONFIG_URL;
Option[0].Value.pszValue = (LPWSTR)pac_url.c_str();

Option[1].dwOption = INTERNET_PER_CONN_AUTODISCOVERY_FLAGS;
Option[1].Value.dwValue = AUTO_PROXY_FLAG_DONT_CACHE_PROXY_RESULT;

List.dwSize = sizeof(INTERNET_PER_CONN_OPTION_LIST);
List.pszConnection = NULL;
List.dwOptionCount = ARRAYSIZE(Option);
List.dwOptionError = 0;
List.pOptions = Option;

if(!InternetSetOption(h_internet, INTERNET_OPTION_PER_CONNECTION_OPTION, &List, nSize))
printf("InternetSetOption failed! (%d)\n", GetLastError());
}
