Request and Response objects

The application of client Request and server Response details in ASP is implemented through the ASP built-in Request and Response object.
· Request object: provides all the information provided by the client when the client requests a page or transmits a form. This includes the HTTP variables that can indicate the browser and the user, and the cookies stored in the browser under this domain name, the value of any HTML control in the <FORM> section of the string or page appended to the URL as the query string. It also provides authorized access using Secure Socket Layer (SSL) or other encrypted communication protocols and attributes that help you manage connections.
· Response object: used to access the Response information created by the server and returned to the client concurrently. Provide HTTP variables for the script, specify the functions of the server and server, information about the content sent back to the browser, and any new cookies that will be stored in the browser for this domain. It also provides a series of methods to create output, such as the ubiquitous Response. Write method.
