* version of that remote include will be used, and the ircd will still boot

* your network. Previously, servers would be unable to boot or rehash when
|
|
* the webserver was down, which would be a big problem (often unacceptable).
|
|
* The latest version of fetched urls are cached in the cache/ directory as
|
|
* cache/<md5 hash of url>.
|
|
* Obviously, if there's no 'latest version' and an url fails, the ircd will
|
|
* still not be able to boot. This would be the case if you added or changed
|
|
* the path of a remote include and it's trying to fetch it for the first time.
