All examples i found of Scrapy talk about how to crawl a single page, pages with the same url schema or all the pages of a website. I need to crawl series of pages A, B, C where in A you got the link to B and so on.. For example the website structure is:
A
----> B
---------> C
D
E
I need to crawl all the C pages, but to get link to C i need to crawl before A and B. Any hints?
