Why are there fewer encoding requirements for POST requests compared to GET requests?
POST places data in the body which can accept binary data, reducing the need for encoding
What is a limitation of URL length for GET requests?
Generally, a URL’s length should be kept to below 2,000 characters, limiting data transmission
What is a common use case for POST requests in web applications?
Submitting login forms
