What is the impact of CORS on web performance?
CORS, or Cross-Origin Resource Sharing, can affect web performance by introducing additional latency due to preflight requests.
Can you explain what preflight requests are?
Preflight requests are HTTP OPTIONS requests sent before the actual request to check if the CORS protocol is understood.
How do preflight requests affect loading times?
They can increase loading times because they add an extra round trip to the server before the actual request is made.
Are there ways to minimize the impact of CORS on performance?
Yes, optimizing server responses and using simple requests can help reduce the impact of CORS on performance.
