# QueryStringConfigProperty

Information about a query string condition.

The query string component of a URI starts after the first '?' character and is terminated by either a '#' character or the end of the URI. A typical query string contains key/value pairs separated by '&' characters. The allowed characters are specified by RFC 3986. Any character can be percentage encoded.

## Example

```ts
// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import { aws_elasticloadbalancingv2 as elbv2 } from 'aws-cdk-lib';
const queryStringConfigProperty: elbv2.CfnListenerRule.QueryStringConfigProperty = {
  values: [{
    key: 'key',
    value: 'value',
  }],
};
```

## Properties

- `values`: [IResolvable](/cdk/api/v2/docs/aws-cdk-lib.IResolvable.html) | [IResolvable](/cdk/api/v2/docs/aws-cdk-lib.IResolvable.html) | [CfnListenerRule.QueryStringKeyValueProperty](/cdk/api/v2/docs/aws-cdk-lib.aws_elasticloadbalancingv2.CfnListenerRule.QueryStringKeyValueProperty.html)[] — The key/value pairs or values to find in the query string.

  The maximum length of each string is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character). To search for a literal '*' or '?' character in a query string, you must escape these characters in `Values` using a '\' character.

  If you specify multiple key/value pairs or values, the condition is satisfied if one of them is found in the query string.
