|
|
* How it works: |
|
15
|
|
|
* - ask for data without auth |
|
16
|
|
|
* - server returns 401 with WWW-Authenticate header |
|
17
|
|
|
* - pass that data to this class to parse header |
|
18
|
|
|
* - fill auth query with data from this class and original query |
|
19
|
|
|
* - ask for data again |
