# ASP Request Object

The ASP Request object is used to get information from the user.

## QueryString Collection Examples

Send query information when a user clicks on a link
This example demonstrates how to send some extra query information to a page within a link, and retrieve that information on the destination page (which is, in this example, the same page).

A QueryString collection in its simplest use
This example demonstrates how the QueryString collection retrieves the values from a form. The form uses the GET method, which means that the information sent is visible to everybody (in the address field). The GET method also limits the amount of information that can be sent.

How to use information from forms
This example demonstrates how to use the values retrieved from a form. We use the QueryString collection. The form uses the get method.

More information from a form
This example demonstrates what the QueryString contains if several input fields have the same name. It shows how to separate input fields with equal names from each other. It also shows how to use the Count keyword to count the "name" property. The form uses the get method.

## Form Collection Examples

A form collection in its simplest use
This example demonstrates how the Form collection retrieves the values from a form. The form uses the POST method, which means that the information sent is invisible to others, and it has no limits (you can send a large amount of information).

How to use information from forms
This example demonstrates how to use the values retrieved from a form. We use the Form collection. The form uses the post method.

More information from a form
This example demonstrates what the Form collection contains if several input fields have the same name. It shows how to separate input fields with equal names from each other. It also shows how to use the Count keyword to count the "name" property. The form uses the post method.

A form with radio buttons
This example demonstrates how to interact with the user through radio buttons, with the Form collection. The form uses the post method.

A form with checkboxes
This example demonstrates how to interact with the user through checkboxes, with the Form collection. The form uses the post method.

## Other Examples

Get the server variables
This example demonstrates how to find out the visitors (yours) browser type, IP address, and more with the ServerVariables collection.

Create a welcome cookie
This example demonstrates how to create a Welcome Cookie with the Cookies Collection.

Find the total number of bytes the user sent
This example demonstrates how to use the TotalBytes property to find out the total number of bytes the user sent in the Request object.

## Request Object

When a browser asks for a page from a server, it is called a request. The ASP Request object is used to get information from the user. Its collections, properties, and methods are described below:

### Collections

Collection | Description
--- | ---
ClientCertificate | Contains all the field values stored in the client certificate
Cookies | Contains all the cookie values sent in a HTTP request
Form | Contains all the form (input) values from a form that uses the post method
QueryString | Contains all the variable values in a HTTP query string
ServerVariables | Contains all the server variable values

### Properties

Property | Description
--- | ---
TotalBytes | Returns the total number of bytes the client sent in the body of the request

### Methods

Method | Description
--- | ---
BinaryRead | Retrieves the data sent to the server from the client as part of a post request and stores it in a safe array
