in section 6 - “Basic System Design and Algorithm” you mentioned that:
If multiple users enter the same URL, they can get the same shortened URL, which is not acceptable.
But why this is not acceptable? It is not a security service but a convenience service. What is a big deal in having the same short url for the same long url regardless of who created this?
Thank you for your posting your query. The author of this course will soon get back to you.
Hi Viacheslav,
There can be a lot of things that the creator would like to do with their short URL e.g., counting how many people clicked a short URL or ad campaign managements like I will create two short URLs and share them in separate ads for Google and Facebook to see how different Ads are behaving.
Hope this answers your question.
