How to get URL from Crawled instead of Scraped from in Portia spider deployment?

Question

I am deploying a Portia spider in scrapyd. While deploying I am passing URLs for every link parsing

Example: The URL(say URL_1) crawled by the spider is http://www.example.com/query1 and the URL(say URL_2) I am passing is http://www.example.com/query2 to extract content.

My spider extracted the content from URL_2 and stored it into respective items. This is fine.

I am having the [URL] item and URL_2 stored in the item, but what I want is URL_1 to be stored in the [URL] item.

Any Solution?
