What is Get and Post request in Asp.net?

GET method:

This method appends form data to page request URL with key value pairs called as query string.

E.g.: http://www.c-sharpcorner.com/home.htm?key1=value1&key2=value2 \

• Page request URL and the form data information (query string) are separated by the ? Character.
• Get method is restricted to send up to 1024 characters only.
• Never use Get method to send sensitive information like password, login information to web server.
• Form data support only ASCII characters.Cannot used to send binary information like word document, text file and image data to server.
• We can access query string in ASP.NET using Request.QueryString["key1"]

Post Method:

• Data transfer through HTTP headers so using secure HTTP protocol we can make sure that data is secured.
• No restriction on sending data size via Post and also we can send binary data or ASCII information using POST method.
