New submission from sicarius noidea <sicarius....@gmail.com>:
Hey,
BadStatusLine triggered when protocol version is in lowercase.
I've encountered a server that answers "Http/1.0 404 Not Found\r\n" instead of
"HTTP/1.0 404 Not Found\r\n"
## Expected Result
Requests understanding the status line.
## Actual Result
Requests is closing the connection.
## Reproduction Steps
### Setup a server that answers the line above
bash: ```while 1;do echo "Http/1.0 404 Not Found\r\n" | sudo nc -lnvp 80;
done```
### get the server
```python
import requests
req = req = requests.get("http://127.0.0.1/";, verify=False, allow_redir=False )
```
## problem location
Look at line 287 of http/client.py
the word "HTTP" should be matched in lowercase too.
```python
if not version.startswith("HTTP/"):```
Regards.
