The idea of this line and the conditional behind it is to retrieve the auth method name. Sometimes this will be just the name keyword (for example: 'NTLM'), but sometimes this will be followed by some optional data (for ex. 'Basic realm="Some site"'). The `indexOf()` will return the index of the space in the latter case, in which the additional data along with the space needs to be removed. This is of cource not needed for the first case.

I assume a short comment above the mentioned line would be sufficient?

Since I have Kerberos configured the original code would only try Negotiate and because it failed it would retry it endlessly. With this patch authentication correctly falls back to NTLM or Basic (if NTLM fails too).
