Difference in the usage of request, request. Form, and request. querystring

Request. Form: obtain the data submitted in post mode.

Request. querystring: Get the parameters in the address bar (data submitted in get mode ).

Request: contains the preceding two methods (obtain the data submitted by the get method first), which are searched in querystring, form, and servervariable.

Sometimes different results are obtained. If you only need data in form, but use request instead of request. form, the program will also search in querystring and servervariable. If an item with the same name exists, different results are obtained.
