How to handle dynamic URLs while crawling online stores?
If you parsing some product pages, usually these URLs have some kind of product id.
Find the pattern to extract product id from URLs, and use it to filter already visited URLs.
I am crawling online stores for price comparison. Mot of the stores are using dynamic URLs heavily. This is causing my crawler to spend lot of time on every online stores. Even though most of them have only 5-6k unique products, they have unique URLs >= 300k. Any idea how to get around this.
Thanks in advance!
