|
|
|
+* This class implements a bridge for http://www.instructables.com, supporting
|
|
|
+* general feeds and feeds by category. Instructables doesn't support HTTPS as
|
|
|
+* of now (23.06.2018), so all connections are insecure!
|
|
|
+*
|
|
|
+* Remarks:
|
|
|
+* - For some reason it is very important to have the category URI end with a
|
|
|
+* slash, otherwise the site defaults to the main category (i.e. Technology)!
|
|
|
+* If you need to update the categories list, enable the 'listCategories'
|
|
|
+* function (see comments below) and run the bridge with format=Html (see page
|
|
|
+* source)
