Ques:- What are Webhooks and how do they differ from APIs
Asked In :-
AnAr Solutions, Shipco IT, Trigent Software, Toxsl Technologies, Codiant Software Technologies, Solace Infotech, Born Commerce, iROID Technologies, Dhruvsoft Services, Infinity Labs LLP,
Right Answer:
Webhooks are user-defined HTTP callbacks that are triggered by specific events in a web application, allowing real-time data transfer. They differ from APIs in that APIs require a request to be made to receive data, while webhooks automatically send data when an event occurs without needing a request.

Ques:- What is CORS and how does it affect API development
Asked In :-
Object Frontier Software, Shipco IT, Walkover Web Solutions, Ziffity Solutions, Trigent Software, Addweb solutions, Codiant Software Technologies, LiteBreeze Infotech, QuickXpert Infotech, Startup - Navya Network,
Right Answer:
CORS, or Cross-Origin Resource Sharing, is a security feature implemented by web browsers that allows or restricts web applications from making requests to a domain different from the one that served the web page. It affects API development by requiring developers to configure their APIs to specify which origins are allowed to access their resources, ensuring that only trusted domains can interact with the API.

Ques:- Design and implement APIs for caching web pages.
Right Answer:
To design and implement APIs for caching web pages, follow these steps:
1. **Define API Endpoints**:
- `POST /cache` - To cache a new web page.
- `GET /cache/{url}` - To retrieve a cached web page.
- `DELETE /cache/{url}` - To remove a cached web page.
2. **Request Structure**:
- For `POST /cache`:
- Body: `{ "url": "http://example.com", "content": "<html>...</html>", "ttl": 3600 }`
- For `GET /cache/{url}`: No body, just the URL parameter.
- For `DELETE /cache/{url}`: No body, just the URL parameter.
3. **Caching Logic**:
- Use an in-memory store (like Redis) or a distributed cache for storing cached pages.
- Implement a TTL (Time-To-Live) mechanism to expire cached entries

Ques:- What is the race around condition? How can it be overcome?
Asked In :-
Recodem, Anlage Infotech (I), Sysco Software, Digital Core Technologies, improbable, macedon technologies, hugo technology limited,
Right Answer:
A race condition occurs when two or more processes or threads access shared data and try to change it at the same time, leading to unpredictable results. It can be overcome by using synchronization mechanisms such as locks, semaphores, or mutexes to ensure that only one process can access the shared resource at a time.
