Re: [PATCH v3 0/1] MR7323: wininet: Treat Expires value "-1" the same as "0"

[Yongjie Yao (＠yaoyongjie)]

In fact, some HTTP server will send "Expires: -1" in HTTP response header.

You are right, HTTP spec is that invalid value, include "0". 

I add a test to test_http_connection() that would send "Expires: -1" in response header, I get the error log:

```
0024:err:wininet:HTTP_ParseDateAsAsctime unexpected weekday L"-1"
0024:err:wininet:HTTP_ParseDate unexpected date format L"-1"
```

Maybe we should just treat "Expires: -1" as an invalid date format and ignore it.
