|
This module is useful where you're only interested in whether the |
|
40
|
|
|
|
|
|
|
file referenced by a URL is present, and don't actually care about |
|
41
|
|
|
|
|
|
|
the contents. |
|
42
|
|
|
|
|
|
|
|
|
43
|
|
|
|
|
|
|
At the moment it just supports HTTP URLs, but I may add other |
|
44
|
|
|
|
|
|
|
schemes, if there's any demand / interest. |
