Question: Web Apllication shows login screen after logged in when i click back button in browser.

I am using spring framework. Is there any Solution for this?

Answer: 
Use:

```
_tfopen(argv[2], TEXT("r")); 

```

Do not use:

```
_tfopen(argv[2], L"r");

```

The second one will give compilation error if the macro `UNICODE` is not defined, that is, when `TCHAR` is just `char`, not `wchar_t`.
Use `_tfopen(argv[2], TEXT("r"));` 

or `_tfopen(argv[2], L"r");` if TCHAR is WCHAR.
