    #### ThrottleByUserIdRule
    This rule limits the concurrent connections of a user. For example, if a user opens multiple browser tabs or logs in using different devices, you can use this rule to restrict the number of concurrent connections for that user.

    #### ThrottleByJwtSignatureRule
    This rule limits the concurrent connections of the same token to prevent malicious users from reusing tokens to establish infinite connections, which can exhaust connection quota.
 
-   **Note:** It's not guaranteed by default that tokens generated by the SDK are different each time. Though each token contains a timestamp, this timestamp might be the same if vast tokens are generated within seconds. To avoid identical tokens, insert a random claim into the token claims.  Refer to [Configure access token](#configure-access-token).

    #### ThrottleByJwtCustomClaimRule
 
    More advanced, connections could be grouped into different groups according to custom claim. Connections with the same claim are aggregated to do the check. For example, you could add a *ThrottleByJwtCustomClaimRule* to allow 5 concurrent connections with custom claim key "freeUser".
 
-   **Key point**: The rule applies to all claims with a certain claim name. The connection count aggregation is on the same claim (including claim name and claim value). The *ThrottleByUserIdRule* is a special case of this rule, applying to all connections with the userIdentity claim.
