Difference between GET and POST

Ch- 6 DWD

Difference between GET and POST

Sr. No	GET	POST
1	GET request is sent via the URL string (appended to the URI with a question-mark as separator), which is visible.	POST request is encapsulated in the body of the HTTP request and can't be seen.
2	GET request goes via URL, so it has a limitation for its length. It can't be more than 255 characters long.	POST request becomes a part of the body of the HTTP request and there is no size limitation.
3	GET request is comparatively faster as it's relatively simpler to create a GET request.	The time spent in the encapsulation of the POST request in the HTTP body is saved in this case.
4	Only ASCII characters allowed. GET request is sent via URL string and as we all know that URL can be text-only, so GET can carry only text data.	No restrictions. Binary data is also allowed. POST has no such restriction and it can carry both text as well as binary data.
5	GET is less secure compared to POST because data sent is part of the URL. Never use GET when sending passwords or other sensitive information!	POST is a little safer than GET because the parameters are not stored in browser history or in web server logs
6	Data is visible to everyone in the URL.	Data is not displayed in the URL.
