738 | * The Java code here will retrieve the page at the given url. If the response code is

739 | * a redirect, it will get the redirect url so that wget may be called with the proper url.
|
---|
740 | * This preprocessing of the URL is necessary because:
|

741 | * Wget does not behave the way the browser does when faced with urls of the form
|
---|
742 | * http://www.englishhistory.net/tudor/citizens and if that page does not exist.

743 | * The directory listing with a slash at the end (http://www.englishhistory.net/tudor/citizens/)
|
---|
744 | * does exist, however. In order to prevent wget from assuming that the root URL
|
---|
745 | * to traverse is http://www.englishhistory.net/tudor/ instead of the intended
|
---|
746 | * http://www.englishhistory.net/tudor/citizens/, we need give wget the redirect location
|
---|
747 | * that's returned when we initially make a request for http://www.englishhistory.net/tudor/citizens
|
---|
748 | * The proper url is sent back in the Location header, allowing us to bypass wget's
|
---|
749 | * unexpected behaviour.
|
---|
750 | * This method ensures that urls like http://www.nzdl.org/niupepa also continue to work:
|
---|
751 | * there is no http://www.nzdl.org/niupepa/ page, because this url actually redirects to an
|
---|
752 | * entirely different URL.
|
