Good day, I'm trying to use different proxies for different threads (a proxy per thread), but it doesn't seem to work. According to Microsoft KB http://support.microsoft.com/kb/226473 : "Note INTERNET_OPTION_PROXY does not permanently change the settings. It does this for the current process only when a NULL handle is used." And it seems to work for different processes (I'm using InternetSetOption with C# like this: [code] public void ChangeIEProxy(string strProxy) { const int INTERNET_OPTION_PROXY = 38; const int INTERNET_OPEN_TYPE_PROXY = 3; Struct_INTERNET_PROXY_INFO struct_IPI; // Filling in structure struct_IPI.dwAccessType = INTERNET_OPEN_TYPE_PROXY; struct_IPI.proxy = Marshal.StringToHGlobalAnsi(strProxy); struct_IPI.proxyBypass = Marshal.StringToHGlobalAnsi("local"); // Allocating memory IntPtr intptrStruct = Marshal.AllocCoTaskMem(Marshal.SizeOf(struct_IPI)); // Converting structure to IntPtr Marshal.StructureToPtr(struct_IPI, intptrStruct, true); bool iReturn = InternetSetOption(IntPtr.Zero, INTERNET_OPTION_PROXY, intptrStruct, Marshal.SizeOf(struct_IPI)); } [/code] My question: how can I use multiple proxies with multiple threads? Thank you. Mures
